Tohoku University Technology: Positive electrode material for magnesium storage battery: T19-070
Realization of sulfur-based positive electrode material from sulfide!
Magnesium battery has being researched and developed as a promising candidate for post lithium ion battery due to its abundant reserve and high capacity per volume. Up to now, a material with chevrel structure was almost the only known positive electrode material for practical magnesium battery. However, the electromotive force is about 1 V which is low, and a material that can generate high electromotive force has been searched. This invention is about a sulfur-based positive electrode material made by electrochemical desorption from sulfide, which can solve above issues. Based on the invention concept, it is able to fabricate a "porous frame + active substance" composite material, and to provide a cathode material with a higher working potential and improved cycle characteristic than conventional material.
