BATTERY CELL HAVING A PROTECTIVE FILM AND AN IMPROVED SAFETY RESPONSE

摘要

What is proposed is: a battery cell (1), in particular a lithium-ion rechargeable battery. The battery cell has a housing (11) and an electrode element (3). The electrode element (3) is in this case arranged in the housing (11). In addition, the battery cell (1) has a protective film (9), which is arranged between the electrode element (3) and the housing (11). The protective film (9) is designed to protect the electrode element (3) from mechanical impact through the housing (11).
