Cathode embedded magnesium ion supercapacitor and preparing method thereof

The invention discloses a cathode embedded magnesium ion supercapacitor and a preparing method thereof. Magnesium ions in the negative electrode embedded supercapacitor a positive electrode, a negative electrode, in between the membrane and an electrolyte, a positive charge can be absorbed by a porous electric double layer formed of carbon materials as the active material, negative use can be embedded / Escape magnesium ions as the active material carbon materials; electrolytic solution using an organic electrolytic solution may be available to provide the magnesium ions and the formation of the desired double layer charge. The supercapacitor can be embedded Mg2 + introduced into the carbon material as the negative electrode supercapacitor, to be able to form a porous carbon adsorption charge the electric double layer as a cathode, anode and cathode materials by optimizing the use of the ratio, the more compatible use with the electrolyte good membrane, so that all the capacity to play an active material, resistance characteristics and other aspects of life to achieve a good balance, with high power characteristics and high energy density, and low cost without pollution.
