  "textContent": "This application provides a battery cell, a battery, an electric apparatus, and a manufacturing method and device of battery cell. The battery cell includes an end cover and a housing, the end cover and the housing forming an accommodating cavity; an electrode assembly accommodated in the accommodating cavity; an insulator configured to isolate the end cover from the electrode assembly; and a protective film fitting around outer circumference of the electrode assembly, the protective film and the insulator being fit together through snap connection. The protective film and the insulator being fit together through snap connection does not require hot-melt connection during assembly, thereby avoiding drawing in over-melting, falling off in under-melting, and the like of the protective film caused by hot-melt connection.",
