Chapter 241 Seizing the Opportunity (Ch 825830347)

Compared to Goldwind Technology, which is still applying for reservations.
Another business is moving even faster.
That is Pengcheng’s Dajiang Innovation, because their company built a battery processing plant in the Shenzhen-Shantou Cooperation Zone.
Since part of the processing technology of the sponge battery is very simple, especially the subsequent assembly part, it can be produced in any small factory.
The battery production department of Hailufeng Company has not had time to develop batteries suitable for drones recently. Of course, this is also related to the fact that there is no unified specification of batteries in the domestic drone industry.
Therefore, Dajiang Innovation had to set up its own battery assembly plant.
Lu Di, vice president of Dajiang Innovation, who has recently been stationed in the Shenzhen-Shantou Cooperation Zone, has been working on the customization of sponge batteries.
Their factory purchases sponge structures from Hailufeng Company and processes them themselves. The purchase price of each cubic meter of sponge structure is 20,000 yuan. After adding other parts, the cost is about 30,000 yuan.
The reason why it is so expensive is that sponge batteries are not cheap on the one hand, 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, holds a small battery and says: “In order to adapt to the use of drones, we have recently adjusted the specifications of the sponge battery cells. At the same time, we changed the outer shell from the previous fiberglass mesh to carbon fiber sealing, which enhances the overall strength and heat dissipation.”
“What changes have occurred in the weight of the battery?” Lu was mainly concerned about the changes in the weight of the battery.
Li Lingfeng replied slowly, “Don’t worry, Mr. Lu. Since we replaced the fiberglass shell with a lighter carbon fiber shell, although the number of positive and negative electrodes in the combined battery pack has increased due to the use of multi-core series and parallel combinations, the overall weight has still dropped by about 3.1%.”
“What about the battery level?”
“According to our battery specifications, if the drone is equipped with similar weight, the power can generally be doubled, thereby doubling the flight time.”
Lu Di thought of something and asked his assistant, “Xiao Wen, have the parts we ordered from Hailufeng’s laboratory arrived yesterday?”
“Yes, it’s here. It should be at the logistics warehouse.”
“You arrange for someone to bring it over.”
“Okay, Mr. Lu.”
Looking at Xiao Wen trotting away, Li Lingfeng turned around and asked, “Boss Lu, what parts did you order?”
Lu Di shook his head. “No, it’s the shell, blades, and brackets of the drone. I found out some time ago that Hailufeng Company has registered a lot of new material patents. I found that some of these materials have good potential, so I contacted the research and development department of Hailufeng Company and customized a batch of parts for experiments.”
During their conversation.
Xiaowen has arranged workers to pull sealed boxes of various sizes from a container to an empty factory building.
Lu Di brought the drone assembly technicians and drone testers he brought from the Pengcheng headquarters to this vacant factory.
Several workers disassembled the sealed box and, following the assembly technician’s instructions, sorted the components into categories and put them into the box.
Using the assembly tools brought from the Pengcheng headquarters, several assembly technicians completed the assembly of a T40 UAV with ease.
The batteries include not only their previous old version batteries, but also special sponge batteries freshly produced from local factories.
The 12 kg sponge battery pack has an effective capacity of 3.15 kWh.
The original battery also weighs 12 kg and has an effective capacity of only 1.57 kWh.
The gap is very obvious.
But this is not the point, because Lu Di and his team did not come here today to test new batteries, because their company had organized more than a dozen tests before.
After a while, another T40 drone was assembled.
But this one is a little different from the first T40.
Five hours had passed and drones were still being assembled in the factory.
Lu Di and others, along with the testers, had already been conducting various tests on the drone in an open space next door.
“The battery life of the T40A, which uses the original battery, has increased by nearly 20%.”
While listening to the report from the test team leader, Lu Di looked at the test report in his hand.
The original T40 drone weighs 38 kg without batteries, and 50 kg with batteries. The payload is 40 kg, which means the maximum take-off weight is 90 kg. However, its maximum take-off weight is 101 kg.
The T40A, which is currently being tested, uses components made of modified soybean silk fiber, which reduces its own weight by 10 kilograms and improves its endurance by about 20%.
The weight of T40B and T40C was reduced by 20 kg and 28 kg respectively.
After preliminary testing, even the extreme weight reduction solution chosen by the Land and T40 design team, the T40C, can still fly.
The next test project is to test the endurance performance of the T40 drones with different weight reduction solutions when using new batteries.
The results are still very eye-catching.
The battery life of T40A has been improved by 113%.
The battery life of T40B has been improved by 133%.
The battery life of T40C has been improved by 149%.
The next day, it was just dawn.
Lu Di and his team continued the testing work that was not completed yesterday.
Today’s testing work is mainly focused on testing the increase in payload.
This test is very important because they want to see how much payload the drone can carry at the same time after switching to the new material.
Perhaps many people would think that the simplest solution is to increase the payload in proportion to the reduction in deadweight.
However, this is impossible.
Because the center of gravity of the fuselage and the payload are distributed differently, the several brackets that serve as load-bearing axes must be able to bear the increased weight.
The test is 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?”
Lu led the way and introduced the situation here: “The current test situation is very good. Even with the extreme weight reduction plan, it can still withstand the test of the maximum takeoff weight of 101 kg.”
“I read part of your report on the way. The maximum weight loss plan is T40C!”
“Yes, Mr. Wang.” Lu Di nodded slightly.
“The ultimate load of the T40C reaches 79 kg. What is the condition of the load-bearing axle?”
“It’s not a big problem. Visual inspection shows no serious deformation or cracks. However, we need to go to the laboratory for more details.”
Wang Tao stood under the parasol.
Lu Di quickly handed over a safety helmet and splash-proof goggles. More than twenty sandbags were piled around the parasol, and a temporary shelter had been set up using tempered glass windows.
While putting on these things, Wang Tao asked, “I heard there was an accident this morning?”
“Yes! A tester was too anxious and got cut by the propeller of an out-of-control drone.”
“How are people?”
“It’s no big deal. I’ll arrange for him to rest for a month.”
Wang Tao squatted down, looked at a tested drone, and touched the propeller blades on it. They were indeed very thin. With very high rigidity, once this thing started to rotate at high speed, it was like a chainsaw.
“What do you think about this situation?”
Lu Di expressed his opinion: “If this new material is really used to make propellers in the future, it can only be made into a grid cage. Otherwise, this thing is too aggressive. If it cuts the throat, aorta, etc., it is very likely to cause death.”
“Making a grid cage will affect flight efficiency and increase weight.”
Hearing this, Lu Di proposed a plan: “Then we can adopt another plan and change the propeller back to the original old material. The propeller doesn’t take up much weight anyway.”
“Well, the new material is so strong that it’s like a blade, spinning at high speed. It’s really too dangerous. There’s no need to take the risk.”
Watched the test for a while.
Wang Tao stood in front of the electric fan and asked again: “Old Lu, has Hailufeng Company given us a price for this material? Or the price for custom parts?”
“Not yet. They have only recently developed this material. And I heard from their person in charge that this material will not be mass-produced until next year when they solve the problem of raw material supply.”
“Next year? It doesn’t matter.” Wang Tao also understood 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 in small batches from Hailufeng Company. Their company is also manufacturing in small batches in the laboratory at this stage.”
Wang Tao nodded: “That makes sense. This investment is very necessary.”
“Yes! With the combination of new batteries and new materials, the performance of our old models has doubled. Hailufeng Company is amazing. I heard that they have batteries with even better performance.” Lu Di exclaimed.
Hearing the latter sentence, Wang Tao smiled and whispered, “It’s already in use.”
“Already in use? So soon?” Lu Di’s eyes widened.
“Our news is definitely a step behind.”
“That’s true.” Lu Di nodded slightly.
Although Wang Tao knew that the high-performance second-generation sponge battery had been secretly put into use, they did not know that the application of sponge batteries was more than just batteries.
If anyone has studied the main components of sponge batteries, they will know that if auxiliary additives are added to this thing, it can be turned into a “molotov cocktail”.
Therefore, after obtaining the high-performance second-generation sponge battery cells, many organizations have been making modifications. After sacrificing some performance, they have added a lot of auxiliary materials. Once the second-generation sponge battery explodes, it can produce an effect similar to that of a napalm bomb.
The use of this thing was suddenly broadened a lot.
However, Wang Tao and others were obviously not aware of the situation.
Before you know it.
The testing on the open space entered a white-hot stage.
Including extreme load-bearing test, extreme destructive test, etc.
In fact, this is not enough. For example, low temperature testing, high temperature testing, ocean testing, desert testing, etc., these tests require professional sites. The facilities in the Ebu Town Industrial Zone are too simple, and the remaining tests can only be carried out at professional testing bases.
In the evening, the sun sets.
“Old Lu, let’s call it a day!”
“Mr. Wang, there’s nothing good to eat here in Ebu. Why don’t we go to Haifeng County? I’ll treat you tonight.”
Wang Tao smiled and nodded: “Okay, I’ll let you host tonight.”
After packing up, the group drove to Haifeng County.
Lu Di, who had been to Haifeng County many times, brought everyone to a village near Lianhua Mountain.
“Old Lu, what delicious food is there in this village?”
“Boss Wang, this village is one of the cooperative tourism areas of Hailufeng Company. I have eaten here several times, and the food in several food stalls is delicious.”
Wang Tao looked at the scenery outside through the car window. The small square at the entrance of the village was full of various cars and several buses. It didn’t look like a mountain village at all.
After getting off the car, Lu Di led everyone to a restaurant called “Lianhuashan Xingwang Food Stall” and asked for a private room.
The windows of the private room face Lotus Mountain.
The setting sun in the evening formed a series of Tyndall light columns in the mountain jungle, and not far away there was a stream flowing through the forest.
After we were seated, the waiter was using hot water to heat the dishes and chopsticks.
Lu Di introduced with a smile: “Boss Wang, the food here is good, but other than the food, the other things are not that interesting.”
“Hailufeng Company also operates in the tourism industry?” Wang Tao took a sip of tea.
“Hailufeng Company does have a lot of industries, but their main industries are derived from agriculture.”
Li Lingfeng, technical director of the battery factory, joked: “Other domestic battery companies are going to vomit blood. They probably didn’t expect that the company that defeated them would be an agricultural company.”
“No one dares to underestimate Hailufeng Company now,” Wang Tao sighed.
It was because Dajiang Innovation attached great importance to Hailufeng Company that they discovered the emergence of modified bean silk materials at the first time 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 key technical aspects of drones are motors, flight control, batteries, and body materials.
Obviously, Dajiang Innovation does not have its own battery, motor, and body material industries. In essence, they are an assembly plant and Internet company.
Therefore, they must always pay attention to the development of various related technologies. If they do not pay attention to the updating of these new technologies, they may quickly fall behind their competitors and be eliminated by the market.
Sponge batteries and modified soybean silk materials are new technologies that can change the drone industry.
If Dajiang Innovation had not paid attention to the emergence of modified bean silk, and other competitors had noticed it, they could easily use this material to reduce the weight of drones and improve their endurance and payload.
This is a crisis.
If you grasp it, it is an opportunity.
If you can’t control it, it will be dangerous.
In this era of 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 dozen or so battery manufacturers in China, although they can continue to survive for a while by relying on the foreign lithium battery market and lithium batteries for home appliances and mobile phones, if they do not find a solution, they will probably collapse in a few years.
However, many entrepreneurs, including Wang Tao, are not optimistic about the prospects of solid-state batteries.
The reason why Wang Tao made such a judgment is the supply of raw materials.
Solid-state batteries are too dependent on the supply of rare elements, which means that the production cost of solid-state batteries cannot be lowered.
After all, rare elements are not only supplied to the battery industry, but also involved in other high-tech industries, such as semiconductors, medical equipment, scientific research equipment, aerospace, nuclear power, etc., all of which require the use of rare elements.
Wang Tao is a science and engineering man, and he knows the prices of rare elements very well. In any case, it is impossible for them to be sold at very low prices in the next few decades.
As for graphene batteries and the like, they are just good-looking PPTs. Even if the performance is achieved, the production cost is estimated to be not low, after all, the process is too complicated.
As for Hailufeng Company’s sponge battery, Dajiang Innovation has built a sponge battery assembly plant and is very clear about the cost of each component of the sponge battery.
Among the components of the sponge battery, the aluminum nitride that serves as the inner liner has the highest cost. When purchased on a large scale, the other components together account for less than one percent of the total sales price.
As for the core sponge structure, it is produced by microorganisms and the cost is estimated to be not much higher.
In other words, no matter how low the cost of solid-state batteries is, they cannot compare to sponge batteries.
Many industries nowadays do not focus on the performance of batteries, but rather on the cost-effectiveness of batteries.
For example, the sponge batteries that are now widely used in energy storage systems have almost reached the maximum cost-effectiveness, with a cost of 0.02 yuan per kilowatt-hour. This cost is obviously not something that ordinary batteries can shake.
“Boss Wang, try the durian this store gave you.”
Lu Di’s voice interrupted Wang Tao’s thoughts. He looked at the durian on the table and asked, “Are the durians here so cheap that they can be given away for free?”
“After all, it’s the place of production. I estimate that the durian supply in Siam will collapse next year.” Lu Di gloated.
Li Lingfeng shared his gossip: “Siam is indeed anxious recently, but it seems that the higher-ups don’t like them very much?”
“If we don’t solve the problems of online fraud and human trafficking, I guess they won’t be treated well.” Wang Tao picked up a piece of durian.
“We really should teach those guys a lesson.” Lu Di also smiled and picked up a piece of durian meat: “At least the durian from Hailufeng is safe. We can’t see how they deal with the durian imported from abroad.”
“Mr. Lu is right. The quality of Hailufeng’s products is indeed good. They dare to let people test them at will, which shows their confidence.”
After taking a bite of durian, Wang Tao wiped his mouth with a tissue: “We need to launch an improved model of our drone as soon as possible. The cargo drone market in Qiongzhou is expanding rapidly.”
Lu Di nodded in agreement: “I think so too. With the performance almost doubled, the value of drone cargo transportation in mountainous areas has also increased a lot. In addition, the rural population is aging seriously, so there is a promising market for agricultural transport drones.”
Wang Tao suddenly remembered something: “By the way, Lao Lu, I heard you say that Hailufeng Company registered a subsidiary for airship manufacturing a few days ago?”
“That’s true. I guess they are planning to use sponge batteries and modified soybean silk materials to build airships. If the airship’s own weight can be reduced by more than half, then the airship’s transportation capacity can be greatly improved.”
Dajiang Company, which has already tested new materials on drones, is very clear about this. Since drones can be used, airships can naturally be used.
