Chapter 239 Quick response
Jiang Miao in-depth discussion on the application prospects of bean silk materials and the layout planning of airship manufacturing during the meeting. After the meeting, he set off for Gongping Town with Qin Hanming.
In the south of Gongping Town, adjacent to Haifeng County, a vast open space has been leveled. Next to the open space are three knitting factories and a schoolbag factory, which have all gone bankrupt and were acquired by the company in March this year.
This factory covers an area of 276 mu, plus the adjacent 1,500 mu of vacant land, has been planned as a production base of the battery department.
Lei Bo, the head of the battery business department, has been stationed here recently. When he heard that the boss had arrived, he hurriedly sorted out his clothes and prepared to welcome him.
Plant entrance. "Boss, welcome to come and guide you." Lei Bo said respectfully.
"Manager Lei, thank you for your hard work." Jiang Miao patted his shoulder with a smile. "This is what I should do. Boss, Manager Qin, please, inside, there is a lot of dust outside, don't affect you two." Lei Bo said as he turned sideways.
Jiang Miao noticed the dust floating in the air, frowned, and ordered as he walked: "The construction party should add dust reduction facilities. Too much dust will not only affect the normal operation of the factory, but will also contribute to nearby residents. Causing troubles is not good for the company's image."
Lei Bo nodded repeatedly, like a chicken pecking at rice: "Okay, boss, I immediately urge the construction party to make rectifications and ensure that it is implemented as soon as possible."
The group did not go to the office building, but went straight to the production workshop .
After several months of contact, Lei Bo has already understood the boss's style, so he directly led Jiang Miao and others to the core area of the production workshop.
He did not take Jiang Miao to visit ordinary workshops such as processing soybean meal, but brought everyone to the sponge structure generation area - this is the largest area and the highest technical content in the entire battery factory.
Wearing protective clothing and protective helmets, after passing through the disinfection passage, everyone entered the sponge structure generation area.
As soon as you step into this area, what you see is the neatly arranged cultivation boxes and a large number of customized versions of LED red and blue lights. The entire space is full of a sense of technology and futuristic sense.
Lei Bo smiled and introduced to everyone: "Boss, Manager Qin, we have recently optimized the production process based on Mr. Lin's second-generation technology."
"How do you improve?" Jiang Miao really didn't pay attention to this matter. He has been doing breeding work and rubber grass planting tests these days.
Lei Bo took out his small notebook and found the recorded comparison data: "There are three breakthrough progress: First, reduce raw material consumption to two-thirds of the original, and reduce the production cycle by 50%; Second, the cycle life has reached 1,200 deep charging and discharging tests, and still maintains 92% capacity; third."
He deliberately paused for two seconds: "Modular design allows the risk of thermal runaway in extreme working conditions. Reduced by 67%. ”
Qin Hanming, who was standing by, made a rustling sound in his pen on his notebook. He raised his head and asked, "Manager Lei, where is the cost control?"
"This is the most surprising part!" Lei Bo raised his head and asked, "Manager Lei, where is the cost control?"
"This is the most surprising part!" Take out a relatively simple cost analysis chart: "Currently, the unit cost of battery cells has dropped by 14.3%, and the weight of the system integration is 23% lower than the previous generation - now each cubic energy storage unit contains a total weight of 1.58 tons, plus the increase in the number of cycles , the cost of kilowatt-hours has approached the critical point of 0.02 yuan. "
Where is the second-generation battery?"
Hearing Jiang Miao's question, Lei Bo quickly explained: "The second-generation battery is We are also producing products, mainly to supply some confidentiality institutions. "
For the improved second-generation sponge batteries, the official took action quickly after seeing the successful technology and half a month ago Hailufeng Company has placed an order to produce a batch of customized versions of high-performance batteries.
After all, the upper limit of battery storage per cubic meter of battery cells in the second generation battery has reached 600 kilowatt-hours, and the number of cycles has been greatly increased.
Although Hailufeng Company does not intend to launch second-generation batteries to the civil market immediately, it does not hinder the official order, because these high-performance second-generation sponge batteries have important uses in many key areas.
Jiang Miao walked slowly in the production workshop and asked slowly: "How much can the production capacity of the first-generation sponge batteries and the second-generation sponge batteries reach?"
Lei Bo replied according to the data he has mastered : "Currently, the first-generation product is 72,000 cubic meters per month, while the second-generation product is 5,000 cubic meters per month."
"When will the new factory be put into use?"
"The construction party said that the first phase of the project can be put into use in August; the second phase of the project will be around the end of this year; and the third phase of the project will be until April next year." Lei Bo continued to add:
"Everything The first phase is a 500-acre factory building, with the production capacity of each phase of the factory building being 100,000 to 200,000 cubic meters of battery cells per month; all the factories are completed, and the annual production of sponge battery cells can be achieved by 3.6 million to 7.2 million cubic meters. ”
This production capacity is almost enough.
Because not only Hailufeng Company is expanding production, but also the annual output of Jingneng Battery and Guodian Battery, which have also obtained technical authorization, is about the same scale.
After all, the core user of using sponge batteries at this stage is the energy storage industry, and the electric vehicle industry has not completely changed to the battery swap mode.
Future cars with basic advantages have been modified relatively quickly. It has been announced that they can fully adapt to the specifications of sponge batteries in August.
Even a certain car company with battery production capacity has announced that it has entered the track of battery swap cars in a low-key manner.
After inspecting the battery factory in Gongping Town, Jiang Miao went to the power dispatching center of Nandian in Shanmei.
Jiang Lincai, the person in charge of the dispatching center, greeted with a smile: "Mr. Jiang, we were a family five hundred years ago!"
Jiang Miao also nodded slightly: "Director Jiang, yours Did the experiment go smoothly? ”
"It went very smoothly, thanks to President Jiang for his strong support." Jiang Lincai replied with a smile.
South China Electric Power Group recently conducted a network disconnection test in Shantou and the United States, which is the experimental result of Jiang Miao's inquiry.
The reason for this test is to do pre-research work in order to reduce costs and increase efficiency in the future.
Then if we want to achieve the goal of 0.3 yuan per kilowatt-hour of electricity to household prices by 2030, the power grid must make plans to reduce costs and increase efficiency.
What does this cost-reduction and efficiency-enhancing plan have to do with network disconnection testing?
The most critical correlation is to test the establishment of an independent distributed micro grid, which is also the key point in solving the cost of the grid.
At present, the comprehensive cost of every kilowatt-hour of electricity sent to users by the power grid is about 0.5 yuan to 0.7 yuan.
The cost of each kilowatt-hour of electricity to the household is:
The power generation cost is 0.25 yuan to 0.35 yuan;
The power transmission and distribution cost is 0.15 yuan to 0.2 yuan; br>
Special funds are RMB 0.05 to RMB 0.08;
Taxes and fees are RMB 0.05 to RMB 0.07.
Because it has a cheap energy storage system, especially the improved sponge batteries and second-generation sponge batteries of Hailufeng Company, the power generation cost of photovoltaic and wind power can be reduced to about 0.04 yuan to 0.12 yuan per kilowatt-hour.
Therefore, the official timetable is that before 2030, the on-grid electricity price for wind power and photovoltaics is 0.1 yuan, which is to force these new energy companies to complete the transformation as soon as possible and strive to compress the power generation capacity below 0.1 yuan, so that they can obtain Spread profit.
At the same time, the official will also adjust special funds and taxes, which can be adjusted to 0.06 yuan in kilowatt-hours.
This means that the power grid also needs to cut off half of the cost in power transmission and distribution.
How to cut the cost of power transmission and distribution?
The key point is on the microgrid.
You should know that the cost of ultra-high voltage construction is more than 10 million yuan per kilometer. In some special areas, such as the Yangtze River cross-river cable, the cost per kilometer reaches about 100 million yuan.
And long-distance power transmission will increase as the distance increases, thereby increasing the power loss.
Some places have a small population. In order to ensure normal electricity use, the power grid still needs to lay lines, especially in many remote villages. To achieve power supply, the transmission and distribution cost will inevitably remain high.
This requires the construction of a microgrid to solve the power consumption in this countryside, directly using photovoltaic panels and sponge batteries.
It is estimated that through this method, coupled with reasonable regulation of valley peaks, the transmission and distribution cost can be reduced by about 30%, and the reduction of the construction of some ultra-high voltage lines, the transmission and distribution cost can be compressed To 0.08 yuan to 0.1 yuan.
Together, the overall cost can be compressed to 0.24 yuan to 0.26 yuan, with an average of 0.25 yuan.
When the overall lower limit of electricity price is 0.3 yuan for kilowatt-hours, the average gross profit of kilowatt-hours is 0.05 yuan. Of course, the electricity cost of residents in some areas is 0.5 yuan for kilowatt-hours, and the profit is not bad.
The charging standard for the power grid to provide various battery swap business enterprises is 0.5 yuan for electricity.
In addition, during this transformation of the power system, the nuclear and thermal power industries cannot suppress the power generation costs, but these two types of power generation cannot be completely abolished.
Therefore, the power grid can only add 0.05 yuan to the overall electricity bill standard, and this part of the superimposed cost will increase the overall electricity bill standard to 0.35 yuan to the thermal power station and nuclear power station. This is a subsidy for thermal power stations and nuclear power stations. Guaranteed fee for large hydropower stations.
Faced with this adjustment, many new energy industries have called for the turn of feng shui.
In the past, optoelectronics and wind power received subsidies.
Now nuclear power, thermal power, and hydropower stations are receiving subsidies. In this process, small hydropower stations are basically dead ends because small hydropower stations are backward production capacity that they need to be eliminated and cannot get subsidies. Their power generation costs are relatively high, so I guess they can only go to mining.
Jiang Miao stayed at the Shanmei Dispatch Center of Nandian Group for less than twenty minutes before returning to the company's headquarters.
As soon as he came back, he heard the report from Business Secretary Liu Deming.
"Boss, one hour ago, Goldwind Technology sent us an application for inspection."
"Goldenwind Technology?" Qin Hanming, who was standing beside him, reminded: "Boss, is one of the large wind power equipment manufacturers in China." Jiang Miao raised his eyebrows: "Oh? They What are you going to see? Sponge battery? "
Liu Deming quickly replied: "There are indeed projects to investigate sponge batteries. Goldwind Technology operates many wind power stations in China, but this time they come here, there is another one. The project wants to investigate, which is the high-strength artificial spider silk that our company recently applied for patent. "
"Their noses are quite good, but they know the rules of our company, right?"
Liu Deming nodded: "I have already sent a reply to the letter, and the other party said there is no problem. If the inspection meets expectations, they are willing to accept our company's payment first and then the goods."
No mistakes, one song, one content One in one in one 6 in nine in one book one bar one!
Hailufeng Company will not be abusive to the bad habits of domestic enterprises. It always pays first and then goods. Generally, it pays 30% first, and then receives 60% of the money. After it is put into use, it will be charged. 10% final payment.
This model is not only aimed at the downstream companies of Hailufeng Company, but also for the upstream suppliers of Hailufeng Company. The company will pay 30% advance payment according to this rule to avoid the supplier's capital chain Too nervous.
Even if a state-owned enterprise is an upstream of Hailufeng Company, it must first pay a 30% advance payment to Hailufeng Company.
Moreover, as long as this company defaults on a single contract, it will be included in the blacklist of Hailufeng Company in the future.
This has forced many companies to change their previous model when facing Hailufeng Company.
In addition, Hailufeng Company also has special terms to restrict these companies for cooperative enterprises that have obtained technical authorization to avoid these companies from making a purchase before orders.
For every industry, this behavior is a kind of internal friction of digging a grave.
Jiang Miao cannot control other industries, but enterprises that use the technology of Hailufeng Company must follow Jiang Miao's rules, which is an unquestionable iron rule.
After all, Hailufeng Company gives you technical authorization, which is not something that allows you to engage in vicious competition with Hailufeng Company.
Goldenwin Technology is willing to accept the rules of Hailufeng Company, so that it will have a foundation for cooperation, otherwise Jiang Miao will not waste time seeing the other party.
In fact, many domestic companies are always paying attention to the troubles of Hailufeng Company.
This time, Hailufeng Company intensively registered patents on artificial spider silk and artificial silk, which attracted the attention of many companies.
For example, when Goldwind Technology applied for inspection this time, they discovered that among the artificial spider silk patents of Hailufeng Company, several patents may be closely related to their manufacturing of fan blades.
Originally, Goldwind Technology was only focusing on the improved patents of sponge batteries, but they only took it seriously after accidentally discovering one of the patents of artificial spider silk.
This patent is called: "A artificial spider silk fiber material prepared by a special process (No. DS12)"
This patent describes a high strength, high rigidity, medium elasticity, Ultra-light artificial spider silk fiber material.
In fact, this is an unexpected product, because whether it is natural spider silk or artificial spider silk, after modification, its rigidity is not high, at least much lower than carbon fiber and glass fiber, and it is basically impossible to As raw material for rigid components.
However, after repeated treatment of boric acid and glycerol three times, artificial spider silk yarn with a special dense nanostructure is formed, and its rigidity is greatly improved.
On average, each time the treatment is treated with boric acid and glycerol, its strength and stiffness will be improved to varying degrees.
One treatment can reach a stiffness of about 62GPa.
The second treatment will improve the stiffness again, reaching about 145GPa.
Three treatments, the stiffness jumps again, which can reach an astonishing 477GPa.
You should know that the stiffness of 477GPa has exceeded the upper limit of carbon fiber, and the upper limit of carbon fiber is 400GPa.
This stiffness is second only to carbon nanotubes with stiffness that can reach 500 to 1000 GPa.
However, the stiffness of carbon nanotubes is indeed a theoretical data. If a weaving process is used and other composite materials are used to produce carbon nanotube bundled materials, the stiffness is only about 50 to 200GPa.
Ideals are full, but reality is skinny.
The reason for this situation is mainly because of the processing technology of carbon nanotubes, which leads to various structural defects that are prone to occur when they are composited with other materials and weaved into bundled fibers.
The modification process of artificial spider silk is different.
At present, when the bean silk laboratory of Hailufeng Company processes artificial spider silk, it often does not process the raw materials. Instead, it first processes the raw materials through textile technology to form the required semi-finished products such as yarn, silk cloth, etc., and then modify it. Sexual treatment.
After the modification process, a special nanostructure will be formed on the surface of the yarn and silk cloth.
However, several consecutive treatments will make the nanostructures on these surfaces increasingly dense and fewer defects.
Only by the third time, the surface of the spider silk yarn has been covered with nanostructures so that it is not airtight, and these nanostructures are firmly combined with the spider silk.
This is the fundamental reason why the rigid strength of artificial spider silk yarns has jumped after the modification process.
In essence.
Artificial spider silk had an unsatisfactory stiffness at the beginning, and it was enhanced by artificial modification, and huge performance mutations occurred.
Carbon nanotubes are on the microscopic scale and have very high strength at the beginning, but after the later composite processing, structural defects appear, resulting in a sharp drop in performance.
The two went to the opposite extreme.
This is also why Hailufeng Company envisioned an airship with super light weight. The reason is that the strength of this artificial spider silk yarn is too strong. If it is used as the skeleton of the supporting structure, half of the structural weight will be reduced. That was a relaxing thing.
Moreover, because the artificial spider silk itself has very good toughness, it also has a very good ability to absorb collision impacts, almost twice that of steel.
This thing can not only be used as fan blade material for wind turbines, but also as body armor, vehicle skeleton, vehicle armor, high-strength cable, aircraft skeleton and shell.
However, the only weakness of modified artificial spider silk yarn is mainly because its heat resistance is relatively poor. Even if it is protected by a special nanostructured shell, its temperature failure limit can still reach 246 degrees Celsius.
Even when the temperature exceeds 200 degrees Celsius, performance changes will begin.
However, this characteristic also has another potential characteristic, that is, if the shell of the material is damaged, it can be done by applying a mixture of glycerin and borax powder and heating it with a hot air fan. Quick fix.
Goldwind Technology is interested in the high strength and rigidity of this material. As long as the price does not exceed carbon fiber, this thing has great value.
After all, the fan blades of wind turbines that are hundreds of meters long nowadays, even if carbon fiber is used, the weight of a single blade is about 20 tons.
If you use a blade that uses a mixture of glass fiber and carbon fiber, the weight will be higher.
When using modified artificial spider silk yarn fibers, the carbon fiber blades can reduce weight by 15%, the carbon fiber and glass fiber mixed blades can reduce weight by 35%, and the glass fiber blades can reduce weight by 50%.
In fact, this is not only related to the weight of the blade, but also to the power generation efficiency. After using lighter and higher-strength materials, the power generation efficiency of the wind turbine can be greatly improved.
Goldwind Technology used supercomputers and after bringing in the material, it found that the power generation efficiency of wind turbines can be increased by 20% to 50%.
If it were the past, Goldwind Technology would probably not be too tempted. After all, before the sponge battery came out, the profit cycle of wind power projects was too long and faced huge risks.
But today is different from the past. With sponge batteries as energy storage systems, the ability of wind power to absorb is no longer a limitation. Now, the higher the power generation efficiency of each wind fan, the greater the profit.
