Embodiment Construction

[0011] exist figure 1 In the illustrated embodiment, the invention comprises a polytetrafluoroethylene layer 1 , polyester fibers 2 . Two PTFE layers 1, polyester fiber 2 sandwiched between two PTFE layers 1. The cross-section of the polymer membrane is sinusoidal. The PTFE layer has the characteristics of anti-acid, anti-alkali, and various organic solvents. It is almost insoluble in all solvents and easy to clean.

[0012] It can be known from common technical knowledge that the present invention can be realized through other embodiments without departing from its spirit or essential features. The above-disclosed embodiments are in all respects illustrative and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are embraced by the present invention.

Abstract

In order to overcome the shortcomings of existing polymer separators, the invention provides a polymer separator, comprising a polytetrafluoroethylene layer, and polyester fibers. The polymer separator can easily utilize the elasticity possessed by the wave shape to release the external force, thereby improving the anti-destructive performance and being easy to clean.

Description

technical field [0001] The invention relates to a device in the field of lithium batteries, in particular to an easy-to-clean polymer diaphragm that can easily utilize the elasticity of the wave shape to release the external force it receives, thereby improving the anti-destructive performance. Background technique [0002] The polymer separator is also called the polymer separator, which is made of one or more polymer materials. It has the function of selective penetration and separation of substances, and can turn ordinary wine into strong alcohol in a few minutes. [0003] At present, the known polymer membrane structure includes polyethylene layer and polyester fiber. The polymer membrane cannot be cleaned easily and is easily contaminated and loses its function. Contents of the invention [0004] In order to overcome the shortcomings of the existing polymer diaphragm, the present invention provides a polymer diaphragm, which can easily utilize the elasticity of the ...
