Hazard description	For the removable portable battery, due to improper management of the battery cell's exterior processing and inappropriate setting of the electrode layer's outer diameter, residual stress from processing and stress from electrode layer expansion may cause cracks to occur in the cell's exterior, leading to electrolyte leakage. This may result in charging failure due to a drop in cell voltage, or, due to metal precipitation caused by the leaked electrolyte, a short circuit may occur, which in the worst case, could lead to the cell igniting and causing a fire.
