METHOD FOR PRODUCING LITHIUM SILICATE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a new method for producing a lithium silicate material that is useful as a positive electrode material for a lithium ion secondary battery or the like by a relatively simple means at low temperatures.

SOLUTION: The method for producing a lithium silicate compound is characterized in that a lithium silicate compound represented by Li2SiO3and a transition metal element-containing substance that contains at least one element selected from the group consisting of iron and manganese are caused to react with each other at 550°C or lower in a molten salt that contains at least one substance selected from the group consisting of alkali metal nitrates and alkali metal hydroxides in a mixed gas atmosphere that contains carbon dioxide and a reducing gas.
