INDIVIDUAL BATTERY CELL FOR A HV BATTERY

摘要

The invention relates to an individual battery cell (1) for a high-voltage battery, comprising an outer shell and a discharge opening (10) which is closed by a material layer (11, 15) in the normal state and which is opened by the at least partial destruction of the material layer (11, 15) when there is excess pressure. The invention is characterized in that a portion (13) of the material of the outer shell is arranged on the exterior of the discharge opening (10) and above it such as to mechanically protect it without preventing gas from being discharged when the opening is opened.
