Abstract

The invention discloses a super-capacitor, and the super-capacitor comprises a housing which comprises an internal housing and an external housing. The internal housing and the external housing form an accommodation space, wherein the gas in the accommodation space is CO2. The super-capacitor also comprises a coiled core which comprises a positive end and a negative end and is disposed in the internal housing. The positive end comprises an upper current collector and an upper cover, wherein the upper current collector is embedded into the upper cover. An upper electrode column is connected with the upper current collector, and the upper current collector is connected with the positive electrode of the coiled core. The joint part of the upper cover and the housing is provided with a sealing ring. The negative end comprises a lower current collector and a lower cover, wherein the lower current collector is embedded into the lower cover. A lower electrode column is connected with the lower current collector, and the lower current collector is connected with the negative electrode of the coiled core. The super-capacitor not only prolongs the service life, but also improves the safety factor.

Description

technical field [0001] The invention relates to a supercapacitor. Background technique [0002] Since the supercapacitor was launched on the market, due to its remarkable advantages such as high power density, long cycle life, good temperature characteristics, and environmental protection, it has attracted widespread attention from all over the world and has become a new industrial highlight in the field of chemical power supplies. It has huge application value and market potential in many fields such as transportation, electric power, communication, national defense, and consumer electronics. In January 2007, the American "Exploration" magazine listed supercapacitors as one of the world's seven major scientific and technological discoveries in 2006, and believed that supercapacitors are a revolutionary development in the field of energy storage. The supercapacitors currently on the market tend to accumulate too high pressure inside, which affects their service life, and th...
