Abstract
An inorganic material based surface-mediated cell (SMC) comprising (a) a cathode comprising a non-carbon-based inorganic cathode active material having a surface area to capture and store lithium thereon; (b) an anode comprising an anode current collector alone or both an anode current collector and an anode active material; (c) a porous separator; (d) a lithium-containing electrolyte in physical contact with the two electrodes, wherein the cathode has a specific surface area no less than 100 m2/g which is in direct physical contact with said electrolyte to receive lithium ions therefrom or to provide lithium ions thereto; and (e) a lithium source. This inorganic SMC provides both high energy density and high power density not achievable by supercapacitors and lithium-ion cells.
