摘要： 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.

摘要： A battery cell for an electrical energy storage device for installation in an electrified motor vehicle having a large number of battery cells. The battery cell includes a cell core and a hybrid cell housing. The hybrid cell housing includes an inner housing element with an outer housing element, and a protection apparatus, by way of which the cell core together with the inner housing element can be ejected from the outer housing element in the event of a (preferably thermal) fault. The outer housing element may include a gas-tight closure in the direction opposite to the ejection direction, the gas-tight closure creating a gas-tight cavity in which, for example in the case of an event that leads to the inner housing element bursting, pressure is deliberately created by gas and used to eject the inner housing element in the ejection direction.
