Problems solved by technology
For high-nickel materials, the contact between the product and carbon dioxide is generally controlled to prevent the lithium hydroxide on the surface from turning into lithium carbonate. After a long time, the internal lithium will diffuse out and become lithium carbonate, which will affect the performance of the product.

Description
technical field [0001] The invention belongs to the technical field of lithium battery production, and more specifically relates to a carbon dioxide concentration control device. Background technique [0002] At present, nickel-cobalt-manganese ternary materials, the cathode material of lithium batteries, have been widely used in the production of lithium batteries. For high-nickel materials, the contact between the product and carbon dioxide is generally controlled to prevent the lithium hydroxide on the surface from turning into lithium carbonate. After a long time, the internal lithium will diffuse out and become lithium carbonate, which will affect the performance of the product. The production and use of nickel-cobalt-manganese ternary materials for lithium battery cathode materials need to control the concentration of carbon dioxide in the air. [0003] At present, the concentration of carbon dioxide in the environment is about 400ppm, while the production and use of ...
