Lithium battery electrolyte is an organic substance without water molecules. If the water content is too high, the product will be scrapped, the quality will deteriorate, and even the product will explode.
Therefore, before the battery is filled with liquid and sealed, it must be vacuum baked. This is necessary, and the purpose is to remove water. Before the battery is filled with liquid and sealed, it must be vacuum baked.
Each cell production factory will bake the lithium battery cells, and the manufacturer will set the relevant cell baking temperature, vacuum parameters, baking time, etc. according to different cell capacities, cell models, sizes, etc., but Basically, most of the baking temperatures are about the same.
