Novel super capacitor diaphragm

Abstract

The invention provides a novel super capacitor diaphragm. The super capacitor diaphragm comprises a ceramic fiber and an enhancement material, and is characterized in that the ceramic fiber and the enhancement material are mixed, and a wet paper-making method is employed for manufacturing an ultrathin, compact, low-resistance and high-strength fiber diaphragm especially suitable for a super capacitor. The advantages are as follows: the super capacitor diaphragm is widely applied to an isolation material of a super capacitor electrode, can well reduce the internal resistance of the super capacitor and improves the work performance of the super capacitor.

Description

technical field [0001] The invention belongs to the technical field of supercapacitors, in particular to a novel supercapacitor diaphragm. Background technique [0002] As a new type of chemical power source, supercapacitors have long service life (100,000 cycles), high specific power, fast charging, low temperature performance, good discharge performance at large flow rates, large energy storage, light weight, maintenance-free, and low pollution. , cheap, and excellent performance, supercapacitors have been used in various fields due to their good performance, and are known as a new type of compact energy. [0003] High power is an important characteristic of supercapacitors, and internal resistance is the main factor directly affecting its internal resistance. As an important part of the supercapacitor, the diaphragm has a great influence on the performance of the supercapacitor. An important part of reducing internal resistance and improving power performance is to redu...

Problems solved by technology

Thicker separators lead to greater resistance of the separator, and higher porosity can cause short circuits in the electrodes. These separators are obviously not suitable for supercapacitors.
