A method for forming a battery wrap film, a battery pack, and an electronic device

Abstract

A method for forming a battery wrap film, comprising: coating a liquid (31) on an outer surface of a soft pack battery (32); and curing the soft pack battery (32) coated with a liquid (31) to obtain awrap film (35) that wraps on the outer surface of the soft pack battery (32), and the wrap film (35) is an integrated film layer; wherein, when the soft pack battery (32) is assembled with an electronic device, the soft pack battery (32) is installed in a battery compartment (33) of the electronic device by the adhesive (34) attached to the wrap film (35). The soft pack battery (32) is taken outfrom the battery compartment (33) by peeling off the wrap film (35) during disassembly. Corresponding battery components and electronic devices are also provided. Since the outer surface coating liquid of the soft pack battery (32) is cured to form the wrap film (35), the outer surface of the soft pack battery (32) can form a good integrated adhesion effect, and the reliability is high. When the soft pack battery (32) is installed in the battery compartment (33) by the adhesive (34), since the wrap film (35) is thin, the wrap film (35) can isolate the soft pack battery (32) from the adhesive (34),so it is easy to peel off and take out the soft pack battery (32).

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a method for forming a battery wrapping film, battery components and electronic equipment. Background technique [0002] Soft pack batteries refer to polymer batteries packaged in aluminum-plastic film, usually lithium polymer batteries, which are mostly used in electronic devices such as mobile phones and tablet computers. [0003] When installing and disassembling pouch batteries in electronic equipment, there are several methods as follows: method (1), the pouch battery is directly bonded to the battery compartment of the electronic device through ordinary tape with adhesive, in this method, due to The surface of the pouch battery is directly bonded to the ordinary tape, so when the pouch battery needs to be disassembled for maintenance, the pouch battery is pulled out of the battery compartment, and the surface of the pouch battery is easily deformed, damaged or wr...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems in the prior art that the adhesion between the wrapping film and the outer surface of the pouch battery is weak, the wrapping effect is poor and the reliability is low, and the wrapping film makes it difficult to disassemble the pouch battery, this application implements The example provides a method for forming a battery wrapping film. A liquid is coated on the outer surface of a pouch battery, and the pouch battery coated with the liquid is cured to form a wrapping film after the liquid is cured, and the wrapping film is integrated. The thin film layer can form a better integrated adhesion effect with the outer surface of the pouch battery, and the reliability is high, and when the pouch battery is installed in the battery compartment through the sticky substance pasted on the wrapping film, due to the wrapping The film is thin, and the wrapping film separates the pouch battery from the sticky matter. When disassembling the pouch battery, it is easy to peel off the wrapping film and take out the pouch battery from the battery compartment
