After the battery cells of the cylindrical battery passes through the rolling groove by battery grooving machine, the next step is very important: drying the battery cells.
Battery cell in the production process will bring a certain amount of water, if not timely removal of water, control it within the standard value range, which will seriously affect the battery performance and safety performance. Generally, automatic vacuum oven is used to dry the battery cells. Put the battery cell neatly into the vacuum oven, put the desiccant in the oven, set up parameters, Heating to 85℃ (with lithium iron phosphate cell as an example). It takes several cycles of vacuum drying to reach the standard.
TOB New Energy can provide the most advanced Lab oven for lithium-ion battery materials and lithium-ion cell baking and drying.
