Abstract: Provided are an insulation patch, a battery cell, a battery, and a device. An electrode assembly is coated with the insulation patch, and a side edge of the insulation patch has a hot-melt region and a non-hot-melt region. The hot-melt region is configured to hot melt with a lower plastic, and the non-hot-melt region is lower than the hot-melt region. After the electrode assembly coated with the insulation patch is mounted to a shell, and the hot-melt region of the insulation patch is hot melted to the lower plastic of a top cover assembly, when a top cover member and the shell are welded together by using a laser, the non-hot-melt region of the insulation patch is lower than the hot-melt region, preventing the non-hot-melt region of the insulation patch from interfering with a welding position between the top cover member and the shell.

Abstract: A battery cell includes a housing having an opening, a cover plate configured to close the opening, and an electrode assembly disposed in the housing and including a main body and a tab extending from an end of the main body along a first direction. The cover plate is located on a side of the main body along a second direction perpendicular to the first direction. The battery cell further includes a first insulation piece disposed between the electrode assembly and the cover plate to dielectrically insulate the electrode assembly from the cover plate, and a second insulation piece disposed between the main body and an inner surface of the housing to dielectrically insulate the tab from the housing. The second insulation piece and the first insulation piece are discretely disposed and connected to each other.
