Tohoku University Technology: Positive electrode material for magnesium storage battery: T18-490
Realization of over 2x high potential characteristic than conventional one!
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 material based on a spinel structure that solves above issues. By employing a defective spinel type oxide that contains defect in the cation site, this invention has succeeded to suppress the crystal structure change due to insertion and desorption of magnesium. As a result, it offers a positive electrode material with higher working potential and improved cycle characteristic than conventional material.
