Abstract

The invention provides a high-performance composite lithium battery diaphragm to overcome the shortcomings of conventional lithium battery diaphragms. The high-performance composite lithium battery diaphragm comprises an ultra-high-molecular diaphragm, a micro cleaning tube, a fixed layer, elastic fixation hooks and an adhesive. Since the high-performance composite lithium battery diaphragm is provided with the micro cleaning tube for cleaning of the diaphragm, recycling is realized; and arrangement of the flexible hooks and coating of the adhesive enhance the adsorption force of the battery diaphragm during installation.

Description

technical field [0001] The invention relates to a device in the field of battery diaphragms, in particular to a high-performance lithium battery equipped with a micro-cleaning tube that can clean the diaphragm for recycling, and equipped with elastic fixing hooks and coated with viscose to enhance the adsorption force of the battery diaphragm during installation Composite diaphragm. 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 contacting and short circuit, and also hav...
