China Battery Magazine - China Battery Network November 18th (Liang Xiaozheng, Beijing Report) at the 3rd China (Wuhan) International Symposium on Lithium Battery New Energy Industry 2015 (ABEC 2015, Lithium "Davos"), Shenzhen Times High Wu Hexin, deputy general manager of Science and Technology Equipment Co., Ltd., delivered a speech entitled "New Automatic Vacuum Drying System for Power Battery". It is reported that more than 550 guests or companies from the global lithium energy new energy industry chain gathered in Wuhan to discuss the status quo, existing problems and explore solutions.
"Water, it has three forms. At the same time, water is very naughty. It is very strong and likes to confuse. Let's take a look at how it is tossed in a battery. First, it will vaporize, swell, and electrolysis. It will follow the electrolyte. The reaction can then crystallize with the material, etc. Then it is a big problem in terms of safety, and it can cause explosions, smoke, and burning.†Wu Hezhen said, “For safety batteries, this safety issue requires more Why is it high? Because a panel is made up of a large number of single cells, its performance is actually determined by a single individual, more precisely by the worst individual The decision, why? When the battery is charged inside, the worst battery is the most likely to be overcharged. Then during the discharge process, the worst battery is easy to over discharge, then it is most prone to severe The reaction, which triggers the reaction of the entire panel, causes many problems.â€
Wu Hezheng said that the power battery must be vacuum-dried. This is a consensus reached by the battery company. However, the vacuum drying method of the power battery is very low in automation. Its disadvantages are obvious, low efficiency, high energy consumption, and consistency. very bad. The low degree of automation has greatly hindered the outbreak of production capacity of the entire automated production line. Faced with a strong market for power batteries that are in short supply, there are times when you can't help but sigh.
How to dry power battery? Wu Helu said that in the materials, pole pieces, pole pieces and batteries can control the moisture, vacuum drying. Taking the negative electrode active carbon as an example, it can be seen that the activated carbon has a lot of capillary pores on its monomers. Its surface area is very large, and the surface area of ​​2 g of activated carbon may be used to coat the entire Groove time slot. The surface of these pore systems absorbs a large amount of water and impurities. This is the object that Times Tech needs to dry.
After determining the water point, the drying can be started. The traditional drying, taking the core drying as an example, builds the drying room first, manually loads and unloads the material, and the individual bellows must complete the preheating, vacuuming, pressure keeping and other functions independently. One person has to complete many functions. In this process, the efficiency is low, the energy consumption is high, the products produced by different monomer bellows are poor, and there are many contacts in the manual handling process, resulting in bad results.
According to Wu and Hao, this is a schematic diagram of the high-tech tunnel type vacuum drying system of the era. It can be seen that there are two rack trucks on the right. The high-tech materials of the times are mounted on a rack truck, enter the tunnel from the rightmost entrance, and move forward. Passed the preheating section, the vacuum drying section, the cooling section, and finally the exit from the tunnel. In fact, this export is directly into the next process. After the material has been discharged, the material has been dried. After unloading, the empty material vehicle passes through the transit of the times and then returns to the front and completes the next cycle. In the process, it can be seen that there is no need for drying rooms, no manual operation, and the working environment in the tunnel is always constant for 24 hours, thus achieving automation, consistency, and low power consumption.
This is the schematic of the high-tech tunnel vacuum drying system of the era. In fact, if the actual schematic is to be refined, it has many and many processes. It can be roughly divided into three segments. This is the theory of the Times High Tech. The technology of the Times High Tech is to divide the individual individual's bellows and several functions it has to complete into separate segments. These segments are professionally completed. A function of its own, and then between the paragraph and the paragraph to open up.
