The first is to confirm and bake the battery material. Generally, the battery conductive agent needs to be baked at 120℃ for 8 hours. The PVDF powder should be baked at 80℃ for 8 hours. The cathode active material (LFP, NCM, etc.) depends on the state and process of incoming material whether it needs to be baked and dried. After drying, (wet process) Mixing the PVDF powder and NMP solvent to make ...
