Abstract

The invention provides a column type super capacitor, and the column type super capacitor comprises : an electrode winding body, a mandrel, a shell, a positive electrode lead, a negative electrode lead and a sealing body, wherein the electrode winding body is composed of one, two or more than two electrode winding members; the electrode winding member is formed by winding a winding piece on the mandrel, and the winding piece is composed of a positive electrode, a negative electrode, a positive electrode collector and a negative electrode collector, a first diaphragm and a second diaphragm which are stacked together in a set sequenceand is of a multi-layer structure; the positive electrode collector and the negative electrode collector are respectively attached to the positive electrode and the negative electrode according to set intervals; the shell is used for wrapping the electrode winding body, the mandrel and the sealing body. The super capacitor can increase the effective contact area of the positive electrode and the negative electrode, and the electrode material adopts a high-porosity covalent organic framework material, so that the specific capacity of the super-capacitor is remarkably increased.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a column-type supercapacitor. Background technique [0002] As a new type of energy storage device, supercapacitor is a new type of power energy storage device with fast charging and discharging between traditional capacitors and rechargeable batteries. Due to its high energy density and power density, wide operating temperature range, and excellent cycle performance, it is widely used in aerospace, national defense digital communication equipment, power supply, storage backup systems, and advanced vehicles such as hybrid vehicles and fuel cells. Battery cars and other aspects have very broad application prospects. [0003] Due to the different energy storage mechanisms, people divide supercapacitors into: 1. Electric double layer capacitors based on the principle of electric double layer at the interface between electrode materials with high specific surface area a...
