Abstract

In order to overcome the defect existing in an existing lithium battery membrane, the invention provides a UHMWPE (Ultrahigh Molecular Weight Polyethylene) composite polyolefin microporous composite membrane. The UHMWPE composite polyolefin microporous composite membrane comprises a UHMW (Ultrahigh Molecular Weight) membrane, titanium alloy membranes, an epoxy anti-corrosion paint layer, a polyethylene glycol layer and micropores. The UHMWPE composite polyolefin microporous composite membrane provided by the invention is provided with two layers of the titanium alloy membranes, so that the strength of a membrane is improved; the UHMWPE composite polyolefin microporous composite membrane is coated with the epoxy anti-corrosion paint layer and the polyethylene glycol layer, so that the corrosion resistance and the hydrophily of the membrane are improved.

Description

technical field [0001] The invention relates to a device in the field of battery separators, in particular to a device with two layers of titanium alloy membranes to improve the strength of the separator, and coated with an epoxy anti-corrosion paint layer and a polyethylene glycol layer to enhance the corrosion resistance and hydrophilicity of the separator. UHMWPE composite polyolefin microporous composite membrane. Background technique [0002] In the structure of lithium batteries, the separator is one of the key inner components. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. A separator with excellent performance plays an important role in improving the overall performance of the battery. The main function of the diaphragm is to separate the positive and negative electrodes of the battery, prevent the two electrodes from contac...
