Chapter 240 Seize Opportunities
Compared to Goldwind Technology, which is still applying for an appointment.
One company is faster.
That is the Dajiang Innovation of Pengcheng, because their company has built a battery processing factory in the Shenzhen-Shantou Cooperation Zone.
Because part of the sponge battery is very simple in processing, especially the subsequent assembly part, you can find a small factory to produce it.
Hailufeng Company's battery production department has not had time to build batteries suitable for drones recently. Of course, this is also related to the fact that there are no unified specifications for domestic drone industry.
So Dajiang Innovation can only set up a battery assembly factory by itself.
Lu Di, vice president of Dajiang Innovation, who has been stationed in Shenzhen-Shantou Cooperation Zone recently, has been working on customizing sponge batteries.
Their factory purchased sponge structures from Hailufeng Company and came back to deep processing themselves. The purchase price of sponge structures per cubic meter is 20,000 yuan. After adding other parts, the cost is about 30,000 yuan.
The reason why it is so expensive is that on the one hand, the sponge battery cell is not cheap, and on the other hand, it is because of the packaging problem of sponge batteries.
Inside the Dajiang Battery Factory in Ebu Town.
Lu Di listened to the descriptions of several technical leaders.
Li Lingfeng, technical director of the battery factory, held a small battery: "In order to adapt to the use of drones, we have recently adjusted the specifications of the sponge battery cell and at the same time turned the shell from the previous fiberglass grid. Changed to carbon fiber sealing, strengthening overall strength and heat dissipation. "
"What changes are there in the weight of the battery?" Land is mainly concerned with changes in the weight of the battery.
Li Lingfeng replied slowly: "Mr. Lu is worried that since we replaced the fiberglass shell, we used a lighter carbon fiber shell, although the combination of multi-core series and parallel lines has led to the combination of the battery pack. The number of positive and negative electrodes has increased, but the overall weight has dropped by about 3.1%. ”
"Where is the battery?"
"According to our battery specifications, if equipped with drones at the same weight as before, the battery can be doubled, thereby achieving battery life."
Lu Di remembers One thing he asked to his assistant: "Xiaowen, did the batch of parts we customized from the laboratory of Hailufeng Company yesterday arrive?"
"It is arrived, it should be in the logistics warehouse. "
"You arrange for someone to come over."
"Okay, Mr. Lu."
Looking at Xiaowen who was jogging away, Li Lingfeng turned his head and asked, "Mr. Lu, what parts have he customized?"
Lu Dishao Shaking my head: "No, it's the shell, blades and brackets of the drone. Some time ago, I found that Hailufeng Company has intensively registered many new material patents. I found that several of them have good potential, so I went to Hailufeng Company's scientific research career The department contacted and customized a batch of experimental parts. "
During the conversation between the two.
Xiaowen has arranged for workers to pull sealed boxes of large and small sizes from a container into an empty factory.
Lu Di brought drone assembly technicians and drone testers brought from Pengcheng headquarters to this vacant factory.
Several workers took the sealed box apart and took each component into the box in different categories according to the instructions of the assembly technician.
Using the assembly tools brought from Pengcheng headquarters, several assembly technicians have completed the assembly of a T40 drone with ease.
The batteries are not only the old versions of their previous versions, but also the specially made sponge batteries freshly released by local factories.
The 12 kg sponge battery pack has an effective power of 3.15 kWh.
The original battery is also 12 kilograms, and the effective power is only 1.57 kilowatt-hours.
The gap is very obvious.
But this is not the point, because today they are not here to test new batteries, because their company has organized more than a dozen tests before.
After a while, another T40 drone was assembled.
But this one is a bit different from the first T40.
Five hours have passed, and drones are still being assembled in the factory.
Lu Di and others have already taken the testers and have already carried out various test work on drones in an open space next door. "The T40A, which uses the original battery, has increased its battery life by nearly 20%. "
While listening to the test team leader's report, Lu Di looked at the test report in his hand.
The weight of the original T40 drone is 38 kg, which is not included in the weight of the battery. The battery is 50 kg and the payload is 40 kg, which means the maximum takeoff weight is 90 kg, but its maximum takeoff weight is 90 kg, but its extreme takeoff Weight is 101 kg
The T40A, which is currently under test, has reduced its weight by 10 kilograms after parts made of modified soybean silk fibers, and its battery life is about 20%.
The T40B and T40C have reduced their weight by 20 kg and 28 kg respectively.
After preliminary tests, even the ultimate weight reduction plan chosen by the land and T40 design team, can still fly.
The next test project is the performance of the battery life of these T40 drones with different weight loss solutions when using new batteries.
The result is still very eye-catching.
The battery life of the T40A has been improved by 113%.
The battery life of the T40B has been improved by 133%.
The battery life of the T40C has been improved by 149%.
The next day, it was just dawn.
The people in the land continued the test work that was not completed yesterday.
Today's testing work is mainly about testing the increase of payload.
This test is very important because they want to switch to new materials and how much payload the drone can simultaneously.
Maybe many people think that the simplest solution is to increase the payload in the same proportion as the self-weight reduction.
However this is impossible.
Because the body's weight and the center of gravity distribution of the payload are different, especially the several brackets as load-bearing shafts, the weight that must be loaded with increased loads.
The test was proceeding in an orderly manner.
At noon, Wang Tao, chairman of Dajiang Innovation, who came from Pengcheng, also arrived at the battery factory.
"Old Lu, what's the situation?"
Take the road on the land and introduce the situation here: "The current test situation is very good. Even if it is an extreme weight loss plan, it can still withstand the maximum takeoff. Test of weight 101 kg. "
"I read some of your reports on the way. The maximum weight loss plan is T40C!" "
"Yes, Mr. Wang." Lu Di nodded slightly.
"The limit load of T40C reaches 79 kg. What is the condition of the load-bearing shaft?"
"No big problem. There is currently no serious deformation or cracks, but in detail, it is necessary to go to the experiment. After passing the room, I checked the flaws."
Wang Tao stood under the parasol.
Land quickly handed over safety helmets and anti-sputter goggles. More than 20 sandbags were piled around the parasol, and temporary shelves had been set up using tempered glass windows.
While wearing these things, Wang Tao asked, "I heard that something happened in the morning?"
"Yes! A tester was too anxious and was cut by an out-of-control drone propeller."< "How are you?" "No big problem, I'll arrange for him to rest for a month." Wang Tao squatted down and looked at a test drone , touched the propeller blades on it, and it was indeed very thin. When the stiffness was very high, once this thing rotated at high speed, it was like a chainsaw.
"How do you think about this situation?" Lu Di said his opinion: "If you really want to use this new material as a propeller in the future, you can only make a grid cage, otherwise the aggressiveness of this thing is too If it is strong, if it is cut into a position like the throat, large artery, etc., it is very likely to cause death. "
"Making a grid cage will affect flight efficiency and increase weight."
Hearing this, Land proposed a plan: "Then use another plan, and change the propeller back to the original old material. Anyway, the propeller does not occupy much weight." "Well, the new material has a very good stiffness. This thing is like a blade, spinning at high speed, which is too dangerous, and there is no need to take risks."
After watching for a while, the test was tested.
Wang Tao Station's electric fan asked again: "Lao Lu, does Hailufeng Company give the price of this material? Or the price of customized parts?" "Not yet, they have only recently studied it. I have produced this kind of material, and I have heard from their person in charge that this material will need to wait next year before they solve the raw material supply problem before mass production will be carried out on a large scale. "
"Next year ? It doesn't matter." Wang Tao also understands this situation.
"Mr. Wang, my idea is this. If we want to use new materials, we need to optimize the center of gravity distribution of some of the current models. We must purchase parts from Hailufeng Company in small batches. Their company is now The stage is also a small batch manufacturing in the laboratory."
Wang Tao nodded: "It makes sense, this investment is very necessary."
"Yes! The new battery and new materials are superimposed, and the performance of our old model is doubled directly. Hailufeng Company is so terrible , I heard they also have better performance batteries. "Land was amazed.
Hearing the words behind, Wang Tao smiled and said in a low voice, "I'm already using them."
"Already use them? So fast?" Lu Di widened his eyes.
"We must be one step slower in our news."
"That's true." Lu Di nodded slightly.
Although Wang Tao knew that the high-performance second-generation sponge battery had been put into use secretly, they did not know that the application of sponge battery is not just a simple battery.
If someone has studied the main ingredients of sponge batteries, he knows that if you add auxiliary agents, this thing can become a "incendiary bomb".
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
So after getting the high-performance second-generation sponge battery cell, many institutions are undergoing magic modifications. After sacrificing part of the performance, a lot of auxiliary materials were added. Once the second-generation sponge battery explodes, Can produce effects similar to napalm.
The purpose of this thing has been expanded a lot at once.
However, Wang Tao and others obviously did not know the situation.
Unclearly.
The test on the open space has entered a white-hot stage.
Includes extreme load bearing testing, extreme damage testing, etc.
In fact, this is not enough, such as low-temperature testing, high-temperature testing, ocean testing, desert testing, etc., but these testing requires professional sites. The facilities in the industrial area of Ebu Town are too simple, and the remaining tests can only be tested at professional testing bases.
In the evening, the sun sets.
"Old Lu, let's finish the work!"
"Dr. Wang, there is nothing delicious here in Ebu. Why don't we go to Haifeng County! I'll treat you tonight." >
Wang Tao nodded with a smile: "Okay, I'll let you do it tonight."
The group packed up and drove to Haifeng County.
I have been to the land of Haifeng County many times and brought everyone to a village near Lianhua Mountain.
"Lao Lu, what's the delicious food in this village?"
"Mr. Wang, this village is one of the cooperative tourist areas of Hailufeng Company. I have eaten it several times, how many times, how many times, how many times The food stalls at home tasted good."
Wang Tao looked through the window glass and looked at the scenery outside. The small square at the entrance of the village was full of various cars and several buses. , not like a mountain village at all.
After getting off the car, Lu brought everyone to a restaurant called "Lotus Mountain Xingbao" and asked for a private room.
The window of the private room faces Lianhua Mountain.
The setting sun in the evening forms a series of Dingdar light beams in the jungle among the mountains, and a stream flows through the forest not far away.
After taking the seat, the waiter was using hot water to scald the bowls and chopsticks.
Lu Di smiled and introduced: "Mr. Wang, the things here are good, but apart from the food, the others are not very fun."
"Hailufeng Company still operates the tourism industry?" Wang Tao took a sip of tea.
"Hailufeng Company does have many industries, but their main industries are derived from agriculture."
Li Lingfeng, technical director of the battery factory, joked: "Domestic Other battery companies are about to vomit blood. They probably didn't expect that the company that defeated them would be an agricultural company. "
"Now no one dares to underestimate Hailufeng Company." Wang Tao sighed.
They Dajiang Innovation discovered the emergence of modified soybean silk materials at the first time because they attached great importance to Hailufeng Company, and then reached a cooperation agreement with Hailufeng Company.
If they are like those battery manufacturers, they will probably be eliminated by the market in a few years.
After all, the technical key of drones is in one aspect, motors, flight controls, batteries, and body materials.
Obviously, Dajiang Innovation does not have its own battery, motor, and body materials industry. In essence, they are an assembly factory and an Internet company.
So they must always pay attention to the development of various related technologies. If they do not pay attention to the updates and replacement of these new technologies, they may quickly lag behind their competitors and be eliminated by the market.
Sponge batteries and modified bean silk materials are new technologies that can change the drone industry.
If Dajiang Innovation does not pay attention to the emergence of modified bean shreds, and other competitors notice it, it is easy for the other party to use this material to reduce the drone's self-weight and improve the endurance and payload.
This is a crisis.
If you master it, it is an opportunity.
If you can't grasp it, it's dangerous.
In this era of such fierce competition, the market will not wait for you to catch up slowly. Once you are overtaken by your competitors, you may experience a cliff-like collapse.
Just like the current dozen domestic battery manufacturers, although they can continue to survive for a while with the foreign lithium battery market and lithium batteries of household appliances and mobile phones, if they don’t find a way, they will probably collapse in less than a few years.
However, many entrepreneurs, including Wang Tao, are not optimistic about the prospects of solid-state batteries.
Why Wang Tao has such a judgment is the reason for the supply of raw materials.
Solid-state batteries rely too much on the supply of rare elements, and this situation destined that the production cost of solid-state batteries cannot be reduced.
After all, rare elements do not only supply the battery industry, but also involve other high-end industries, such as semiconductors, medical equipment, scientific research equipment, aerospace, nuclear power, etc., which require the use of rare elements.
Wang Tao is a science and engineering man. He is too clear about the price of rare elements. Anyway, it is impossible for a bargain price to occur in the next few decades.
As for graphene batteries, this thing looks good, even if the performance is achieved, the production cost is probably not low, after all, the process is too complicated.
For Hailufeng Company's sponge battery, Dajiang Innovation has built a sponge battery assembly plant, and the cost of each component of the sponge battery is very clear.
The highest cost among the components of sponge batteries is aluminum nitride as the inner liner. When other parts are purchased on a large scale, the total price is less than 10% of the total selling price. one.
As for the core sponge structure, this thing is generated through microorganisms, and the cost is estimated to be much higher.
In other words, no matter how low the cost of solid-state batteries is, they cannot compare to sponge batteries.
Now many industries do not value the performance of batteries, but the cost-effectiveness of batteries.
For example, the sponge batteries currently used on a large scale in energy storage systems have almost full cost performance, reaching a kilowatt-hour cost of 0.02 yuan. This cost is obviously not something that ordinary batteries can shake.
"Dr. Wang, try the durian given by this store."
Lu Di's voice interrupted Wang Tao's thoughts. He looked at the durian on the table: "The durian here is the durian. Are you all so cheap that you can just give it? ”
"After all, it is the place of origin. It is estimated that the durian in Siam will collapse next year." Lu Di was gloating.
Li Lingfeng said his rumor: "Siam is really anxious recently, but it seems that the superiors don't like them very much?"
"If you don't solve the problem of telegram fraud and trafficking, I guess you won't It will give them a good look." Wang Tao picked up a piece of durian.
"We should indeed teach those guys a lesson." Lu Di also smiled and picked up a piece of durian meat: "Hai Lufeng's durian is at least safe. We can't see how they deal with durian imported from abroad." "Mr. Lu is right. The quality of Hailufeng Company's products is indeed good. They dare to let people test them casually, which is the confidence."
Tasting a piece of durian, Wang Tao picked up a tissue and wiped his mouth: "Our drone needs to be launched as soon as possible. The freight drone market in Qiongzhou is expanding rapidly."
Lu Di nodded in agreement : "I also think that with almost doubled performance, the freight value of drones in mountains has also increased a lot. In addition, the rural population is now seriously aging, and the market for agricultural transportation drones has great potential." >
Wang Tao suddenly remembered something: "By the way, Lao Lu, I heard from you that a few days ago, Hailufeng Company registered a subsidiary of airship manufacturing?"
"It's true In fact, I guess they plan to use sponge batteries and modified bean silk materials to make airships. If the airship's self-weight can be reduced by more than half, the airship's transportation capacity can be greatly improved. "
For this, Dajiang, which has conducted new materials testing on drones, is very clear that since drones can be used, airships can naturally be used.
