Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of stock bin more specifically, the utility model relates to a kind of composite nonmetal stock bin. BACKGROUND

[0002] Lithium ion battery, as the mainstream energy storage equipment, its application in various fields has become more and more widely. The positive material, as the core component in the battery, its performance directly determines the overall performance of the battery. And about the failure mode of the positive material, we can not ignore several key issues: the mixing of metal foreign matter, excessive moisture and poor batch consistency. These seemingly small factors actually have a profound impact on the performance and safety of the battery. The mixing of metal foreign matter is a problem that cannot be ignored. In the production process of the positive material, the presence of any metal impurities can cause serious consequences. These metal impurities will be oxidized during the battery formation stage, and then reduced at the negative electrode. When the metal elements at the negative electrode accumulate to a certain extent, the hard edges of the deposited metal will pierce the separator, causing self-discharge of the battery. Self-discharge not only shortens the life of the battery, but in severe cases can even cause safety accidents. Therefore, it is particularly important to prevent the mixing of metal foreign matter from the source. One of the equipment control methods is to avoid using materials containing lead (Pb), copper (Cu), zinc (Zn) and other metals in the part of the equipment that comes into contact with the raw materials, and to use isolation methods to prevent the mixing of metal impurities from the equipment itself into the processing air.

[0003] 1. The containers and stock bins used in traditional production lines are made of stainless steel. In theory, 304 stainless steel does not contain lead, zinc, and copper, but during the production of stainless steel materials, trace elements may be mixed in.

[0004] 2. To further isolate lead, zinc, and copper, the industry currently uses a plating layer in stainless steel containers for isolation. The cost of the isolation plating layer is very high.

[0005] 3. Lithium raw materials will continuously rub against the plating layer during the transfer process, causing the plating layer to be damaged and ineffective, and the damage points are difficult to detect.

[0006] Therefore, a composite nonmetal stock bin is proposed. UTILITY MODEL CONTENT
