Calcium battery and its electrolyte and composition

New Ca electrolyte composition which satisfies all essential properties required for rechargeable battery

Overview

　The Ca-rechargeable battery is expected to replace the Lirechargeable battery in the future, but there is no electrolyte having the essential characteristics for a rechargeable battery.
　This invention solves above problems and realizes an electrolyte solution for Ca-rechargeable battery with high Ca-ion conductivity, large potential window, and high stability of metal dissolution & precipitation against Ca with limited property degradation, using a novel composition halogen-free Ca salt.
