Battery encapsulating method and battery

Abstract

The embodiment of the invention discloses a battery encapsulating method which reduces the phenomenon that a plastic part is not matched with a battery cell, and a battery prepared by the method. The method is based on a low-temperature injection molding device and comprises the following steps of: providing the battery cell which is connected with a protective plate; performing sleeve joint on the battery cell which is connected with the protective plate and a plastic shell which is provided with an injection hole, and making a terminal on the protective plate opposite to a terminal window of the plastic shell; and injecting a low-temperature injection molding material into the plastic shell through the injection hole by using the low-temperature injection molding device. After the battery cell is in sleeve joint with the plastic shell, the low-temperature injection molding material can be injected into the plastic shell through the injection hole on the plastic shell. After being condensed, the injected low-temperature injection molding material can play a role in filling gaps between the plastic shell and other components and bonding the plastic shell with other components. Even an oversized plastic part can be tightly connected with the battery cell under the action of the low-temperature injection molding material, so that the phenomenon that the plastic part is not matched with the battery cell is reduced.

Description

technical field [0001] The invention relates to the technical field of packaging, and more specifically, to a battery packaging method and a battery. Background technique [0002] The assembly process of plastic parts is a common packaging method in the field of battery packaging at present. This method first needs to form a plastic shell, bottom gasket or internal bracket through a fixed mold (the above-mentioned plastic shell, bottom gasket and internal bracket can be collectively referred to as plastic parts), and then assemble: connect the protective plate to the battery core Together, put a plastic casing on the outside of the protective plate and the battery core, align the terminals on the protective plate with the terminal windows of the plastic casing, and obtain a packaged battery. [0003] However, when implementing the present invention, the inventors found that when using plastic parts for assembly, the problem of mismatch between the plastic parts and the batt...

Problems solved by technology

[0003] However, when implementing the present invention, the inventor found that when using plastic parts for assembly, it is easy to have the problem that the plastic parts do not match the batteries

For example, the size of the plastic part is too large, and it cannot be firmly connected with the battery cell
