New electrode material for solid-state batteries improves performance

Green Car Congress

An all-solid-state lithium battery using inorganic solid electrolytes requires safety assurance and improved energy density, both of which are issues in large-scale applications of lithium-ion batteries. Operational difficulty of all-solid-state batteries using them generally lies in the construction of the electrode-electrolyte interface.
