What are the experiences of the perfect lithium battery powder processing system?

The lithium battery industry attracts hundreds of billions of dollars, and the gold compass points to where. The 2018 China International lithium battery and Electric Technology Development Summit Forum held in Shanghai on April 20-21. The conference was held by: First Lithium Grid, First Electric Vehicle Network, China Charging pile net, lithium battery 100 people, He Li exhibition co-hosting, the same period: China International Electric Vehicles and Charging and Recharging Technology Summit Forum, more than 40 guests attended the speech, more than 500 guests attended, and more than 20 companies Set up booths to promote the latest technologies and products.

Shen Jie: The BRICS Lithium Summit, just said very well, China must have its own core technology, then where do we say core technology? It is impossible to rely on copying. We must innovate. What is the internal driving force of our innovation? Intrinsic power is constantly pursuing perfection, so our Guangzhou Chuangte Technology Co., Ltd. is committed to the upstream of these powder productions as well as the development of downstream electronic powder preparation process, the most important of which is the powder system, which is technically difficult on top of the powder. What is the powder in the end, we have to clean the raw material powder into the mixer according to the required formula, in this sentence, the clean inside is that the dust must be controlled, then the raw materials according to the required formula, we Be sure to control the precision of various raw materials, then put in the mixer, it is very difficult to put this material into it, there are a lot of technical content inside, there are many mistakes in the mixer, it may be called good investment Into the mixer, there is residue in the weighing tank. There is residue in the pipeline and inner wall during the mixing process, so the cost is high, how can it be lowered? We have a lot of talk on our equipment.

Chuangte is pursuing perfection, how to pursue perfection? We first wanted to automate this manual ingredient and manual feeding. Everyone knows that powder and liquid have earth gravity. They can go from top to bottom. Many people use 30% to try and move from the 2nd floor to the 1st floor. Until now, many manufacturers are going from the 2nd floor to the 1st shot. This thing has no technical content, and there are many problems in it. We need a more professional team. We need the company to do research in this area, which can solve 90% of the problems, but our batteries have to be world-class batteries. Who do we sell to? BMW, Mercedes-Benz, Tesla, they will come to see that our system must not only be used, but also easy to use, but also look good, we have 10% of artistic cells, which will make the system perfect.

After 17 years of hard work, the first line in China was made by us. In 2003, the lithium battery industry was a venture capital stage. The first factory of ATL China was in Shenzhen Baima Industrial Park, 4 floors, the first time It was quite successful. At that time, the first system used a pre-mixing system. It was pre-mixed once in the mixer, and the ratio was correct. After the ratio was good, it was stirred in the disperser. This system should be the most stable then with the development of production technology, they need to directly put this material into the mixer. At that time, because everyone used the mixing time for a long time, so there were more than 20 mixers in the mining workshop. One cycle is 12 hours then we consider the material balance, because the ingredients are relatively short, only one ingredient station is made, and the good material is put into the mixer, which produces a one-to-many system with negative pressure. This system works well. But there are some problems. At that time, the gear of the mixer was exposed to the outside. My powder was lifted at a high speed, the gear was stuck, and the loss was very large. Now The gearboxes of some mixers are closed. Because we made some improvements at that time, we solved these problems. After solving them, the system is not perfect because it is negative pressure, virtual image delivery, and it is very large airflows are coming in, more storage is needed, and there may be a lot of residue. This problem affects the formula. Based on this, we developed a third system. In 2009, we won the title of high-tech in Guangdong Province, 2011. At the time of the third generation, we used a very very high proportion, the material is pressed inside, the effect is equivalent to hand feeding, basically no airflow, to what extent? Seeing that the powder inside is a stock that walks in, very slow, this system is very stable, but there is a problem, the powder is taken from the scale every time the feeding is added, and it is necessary to send it back when it is re-weighed, maybe With systematic errors, it is difficult to define whether there is any residue. This system is based on the defects of the third generation system. We have developed the fourth generation system, which is the auxiliary material sending tank. When we make the battery, the auxiliary materials have some density. The low material, we will not push it away, put it fixed, a tank to all the mixers, send it remotely in the form of a sending tank, so that it is sent out, but your name is not moving. It doesn't need to be re-named. It's easy to know if all the materials are hit out. Then, by 2013, the ultimate problem was not solved. The density of iron phosphate and lithium was very fine, and the real density was very large. How many of these powders are one or more, these are not as light as toner, and it is easy to send them. The density is very heavy, and it takes a lot of pressure. There is no way to send these materials in the existing systems in the world. It can be said. We have worked hard for another four years. We developed new things last year. This set of things is the first in the world. Now only our company has a main material called peristaltic conveying one-to-many. This is the ultimate solution, so that after that, the iron phosphate is creepy. The method is sent to the mixer, does not need to spend too much dose, does not need to use too many compression tools, this has been applied in many projects. From this journey, we are constantly attacking new targets, and we want to have problems with existing systems every time.

Ok, what are we doing today? Our company always wants to work hard in this industry, to achieve the world-class level, we continue to develop new things, and now there is still a problem we have not solved is how do you solve the internal wall of the mixer The problem, the way the material is transported or the dry shape will have the problem of wall hanging. Now there is a spray method, we cannot solve this problem without spraying. This is our topic today. This is our accumulated customer in the lithium battery industry for so many years. There are downstream anodes and cathodes in the upstream and finished products. Are there any manufacturers of finished lithium and lithium batteries? We are all doing research, right? As long as it is the upstream of the lithium battery, it is the cathode material, the anode material or the production material like the ATL downstream of the lithium battery, and Tianyu can cooperate with us, we can provide you with the most advanced system.

This is the material we have handled. I just said the perfect system. This is a traditional system. What is the difference between these two systems? The traditional system has two floors. You can see that the current battery production has two floors. The upstairs is a laboratory, an office, and a warehouse. It does not need to be used as a production workshop. This is too backward. Now our system is a one-story building. Ingredients, produced there, there are two mixers on this picture, which can extend a lot of mixers, and the layout of the production workshop will be very good in the future.

Then, based on our core technology, we can do all these systems before coating, because it is a liquid, powder, if it is a professional liquid, it is more difficult to make powder, but the powder is based on liquid. There is no problem with our system for liquids, and there are similar materials for lithium ternary carbonate, our peristaltic transport technology is a star technology, this is only our company so far, this thing is currently operating very well and very efficient.

Then there is dust overflow, the suction wind speed is 1M/S. I have looked at people in many industries. The filter cartridge inside it is very small. Our system filter cartridge is very large, long distance conveying, why has it been in the workshop, why can't it? In the warehouse, the ingredients in the warehouse are sent to the scene to be cattle. We have the technology of long-distance transportation. This is no problem. We used to do chemical industry, 100M, 200M does not matter.

How to ensure high precision, we are one thousandth, there is a very powerful thing here according to the results of each batch the strategy of the next batch is decided. Our powder is very poor in fluidity, how to ensure that all the materials in the sending tank are sent away. There are a lot of techniques in it. The top is soft, the bottom is porous, and then you can also mix when you are transporting.

So based on our technology, we can do a lot of modern factory management, using big data and intelligent decision systems to track products. This is the patent we have applied for in this industry for 17 years and many innovative technologies. In the future, lithium batteries will also develop on a large scale, because of the personnel problem, because China's power generation capacity is very large, and there is a lot of excess. It is imperative to use lithium batteries. After that, the production of lithium batteries cannot be done in the workshop with small mixers. This set of production lines is newly developed and can be continuously produced and mass produced. The scale material of the lithium battery is not a small cylinder, but a large cylinder.
