Abstract

The invention provides a battery. The battery comprises a shell, a battery cell, an insulating film and a cover plate, the insulating film includes an interlayer region. And the interlayer area is positioned between the cover plate and the top surface of the battery cell. And the cover plate is attached to the top surface of the battery cell to fix the interlayer area. And the insulating film is folded from the interlayer area to the free end of the battery cell to wrap the battery cell. According to the battery, the battery cell is wrapped by the insulating film from top to bottom, so that the problem of short circuit of the battery caused by damage of the plastic film on the outermost layer of the battery cell is solved. Meanwhile, according to the battery disclosed by the invention, theinsulating film can be fixed between the battery cell and the cover plate without adopting a retainer, so that the equipment investment cost is reduced, the production space is reduced, the operationenergy consumption is reduced, and the energy density of the battery is improved.

Description

technical field [0001] The present application relates to the technical field of battery manufacturing, in particular to a battery and a battery preparation method. Background technique [0002] As mobile device technology advances, the demand for rechargeable batteries continues to increase. Low-capacity rechargeable batteries can be used in mobile phones, notebook computers, and portable video cameras, etc., while large-capacity rechargeable batteries can be used in power supplies for electric vehicles, etc. [0003] Lithium-ion power batteries are widely used in the field of electric vehicles. The mainstream lithium-ion power batteries in the industry mainly include three types: square, soft pack and cylindrical. Among them, prismatic lithium-ion batteries are widely used because of their high grouping rate, low PACK cost and high system energy density. At present, the main structure of a square lithium-ion battery (hereinafter referred to as battery) includes: a cover...
