Double-carbon and double-MXene pole ion high-performance battery

Abstract

The invention belongs to the technical field of a battery, and discloses a double-carbon and double-MXene pole ion high-performance battery. Carbon nanometer materials including carbon nanotubes and graphene are used; MXene, foamed carbon, mesoporous carbon, carbon fiber and conductive carbon felt have two electrodes and are used as current collectors; silver, copper, aluminum, chromium, titanium,barium, nickel, molybdenum, cobalt, platinum, zinc, iron ion / oxide powder and acid or alkali or salt type ion liquid and natural inorganic liquid are selected and mixed into electrolyte. The chargingtime is short; due to the characteristic that the surface of the carbon type product is great, the charging can be completed in 10 minutes; seven thousands of times of charging and discharging cyclesare reached. The battery specific energy reaches 92Wh / kg; the coulombic efficiency can reach 95 percent. The discharging voltage ranges from 1.5 to 2V; the average discharging voltage is 1.7V.

Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to a high-performance double-carbon and double-MXene polar ion battery. Background technique [0002] Because all kinds of vehicles in the world, communication, office, computer, mobile phone and household electronic products all use batteries, especially secondary rechargeable batteries. [0003] In the case of safe use, people are pursuing: first, the rapid development of green and environmentally friendly batteries, including lithium-ion batteries, nickel-hydrogen batteries, etc.; second, the transformation of primary batteries into batteries, which is in line with the sustainable development strategy; , light and thin direction. [0004] In terms of material selection, there are silver, zinc, foamed copper, foamed aluminum and the above-mentioned carbon fiber, etc.; carbon is one of the most closely related and important elements in nature, and the four electrons in its outer...

AI Technical Summary

Problems solved by technology

[0018] However, the explosion problem of the liquid used in lithium-ion batteries and lithium itself cannot be solved so far.

For example: Samsung 7S mobile phones are not allowed to be carried on the plane at present; the lithium batteries of electric charging vehicles explode and cause death.
