Abstract
Embodiments of the present application provide a battery cell, a battery, a power consumption apparatus, a method for producing a battery cell and an apparatus for producing a battery cell. The battery cell includes: a pressure relief mechanism, the pressure relief mechanism being disposed on at least one wall of the battery cell; and a protective film enclosing an outer surface of the at least one wall, the protective film being configured to provide insulation protection for the at least one wall; where the protective film includes a first portion at least covering the pressure relief mechanism. Through technical solutions of the embodiments of the present application, insulation performance of a battery cell could be improved; meanwhile, deformation of a pressure relief mechanism could be suppressed, creep of the pressure relief mechanism could be reduced, and the service life of the pressure relief mechanism could be increased.
