π¨βπ«π¨βπ«π¨βπ«Why is there strict humidity control during the production process?
In the manufacturing process, factors such as slurry dispersion, compaction density, negative-positive ratio, temperature control, electrolyte volume, and cell internal pressure will directly affect the expansion of the cell. Especially water, because the highly active lithium-carbon compounds formed by charging are very sensitive to water, resulting in a violent chemical reaction. The gas produced by the reaction causes the internal pressure of the cell to increase, increasing the expansion behavior of the cell. Therefore, in production, in addition to strictly dehumidifying the pole piece, dehumidification equipment should be used during the injection process, such as a glove box, to ensure that the dew point is less than -50β.
