Water, it has three forms, and the water is also very naughty, the ability is very strong, like to mess. Let's take a look at how it is tossing inside the battery. First, it will vaporize, expand, and electrolysis will react with the electrolyte, then it can form a crystallization with the material.

Then it is a big problem in security, there will be explosion, smoke, burning. Wu He Wei said that in terms of the power lithium battery, this security issue is more demanding, why? Because a panel is composed of a lot of monomer batteries. It is actually determined by a single individual by a single individual.

What is more specifically determined by the worst piece of a single individual? When charging is charged in the battery board, the worst battery is most likely to be charged. So, in the process of discharging, the worst battery is easily over, then it is most likely to have a dramatic reaction, thus causing the reaction of the entire panel, thus causing a lot of problems. The power lithium battery must be dry, which is a consensus that the battery company is self-evident, but the automation of the current dynamic lithium battery is very low, its shortcomings are quite obvious, low efficiency, high energy consumption, consistency is very Difference.

The degree of automation is low, which has greatly hindered the outbreak of the entire automated production line. Faced with a good market for unscrupulous power lithium batteries, sometimes you can only look at. How does the power lithium battery dry? Wu Hezhen said that in the material, the pole roll, the pole and the electrical circular link can control moisture, do vacuum drying.

Taking the active carbon activated carbon as an example, it can be seen that the activated carbon is contrary to a lot of capillary apertures, and its surface area is very large, and the surface area of ​​2 g of activated carbon can be applied to the entire groove. The surface of these holes absorbs a lot of water, impurities, this is the object to be dry. After determining the control water point, you can start drying.

Traditional drying, drying with the core as an example, first build a dry room, artificially prepared, the monomer wind box should independently complete a number of functions such as preheating, vacuum, and preparation , One person wants to complete a lot of functions. In this process, the efficiency is low, the energy consumption, the difference in the product of different monomer foil, and there are many contacts in the process of manual handling, causing bad results. According to Wu Hao, this is a schematic of the tunnel vacuum drying system.

You can see that there are two shelf vehicles on the far right. The material is loaded on the shelf vehicle, from the rightmost entrance to the tunnel, move forward, respectively Segment, vacuum drying section, cooling section, finally from the tunnel. In fact, this export is directly entering the next step.

After coming out, the material has been drought, after unloading, the no-load material vehicle, through the transfer, then reflow, return to the front end, complete a cycle of the next paragraph. It can be seen in this process, do not dry the room, no manual operation, the working environment in the tunnel is always constant 24 hours, thereby achieving automation, consistency, low power consumption. This is the schematic diagram of the tunnel vacuum drying system.

In fact, the actual schematic is refined, it has many more processes. It can be roughly like this, there are three paragraphs, which is the theory, process, which is a single function of the original monomer, it is divided into independent sections, these specializes in completing each of their own functions, then Sustained to the segment. .
