Lithium intercalating material containing oxygen, sulfur and a transition metal, electrode structure and production process thereof, and secondary lithium battery

摘要

Disclosed herein is a powder material comprising a compound which electrochemically intercalates and deintercalates a lithium ion, wherein the powder material is comprised mainly of a compound containing at least an oxygen element, a sulfur element and at least one transition metal element MT, wherein the molar ratio of oxygen to sulfur is 0.1 to 100, and the molar ratio of (O+S)/MT is 1.0 to 3.0. There is also inclosed an electrode structure for a Li intercalating battery comprising said powder material, and a process for producing said electrode structure. Furthermore, there is disclosed a secondary Lithium battery fabricated from at least a negative electrode, a positive electrode, an electrolyte and a battery case and utilizing the intercalation and deintercalation reaction of Li ions for charging and discharging, wherein the negative and/or positive electrode is comprised of an electrode containing, as a main component, said powder material.
