Capacitor battery of high-specific-energy organic system

Abstract

The invention relates to a capacitor battery of a high-specific-energy organic system, consisting of a positive electrode, a negative electrode, a diaphragm between the positive electrode and the negative electrode, and organic electrolyte, wherein the positive electrode adopts the mixture of a lithium-ion-embedded compound and a porous carbon material, the negative electrode is hard carbon, and the electrolyte adopts electrolyte of an organic solvent containing lithium ions. The super capacitor battery prepared by the invention has the characteristics of high energy density (up to 20-90Wh / Kg) and high power density (larger than 4500W / Kg), can be widely applied in the fields such as electric automobiles, electric tools, solar energy storage, wind energy storage, portable household appliances and the like.

Description

technical field

[0001] The invention belongs to the technical field of capacitors and batteries, and relates to supercapacitors, in particular to organic hybrid supercapacitors and lithium ion batteries. Background technique

[0002] Supercapacitor is a new type of electrochemical energy storage device between traditional capacitors and batteries. Compared with traditional capacitors, it has higher energy density, and its electrostatic capacity can reach thousands of farads to 10,000 farads. Compared with batteries, it has higher High power density and long cycle life, so it combines the advantages of traditional capacitors and batteries, and is a chemical power source with broad application prospects. It has the characteristics of high specific capacity, high power, long life, wide working temperature limit, and maintenance-free.

[0003] According to different energy storage principles, supercapacitors can be divided into three categories: electric double layer capacitors...
