POSITIVE ELECTRODE MATERIAL FOR SECONDARY BATTERY AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode material for a secondary battery and a manufacturing method for the positive electrode material in which a manganese fluorophosphates oxide LiXNa2-XMnPO4F simultaneously containing lithium and sodium can be used as an electrode material.

SOLUTION: A positive electrode material of a lithium battery can be provided which is made usable as an electrode raw material by manufacturing LiXNa2-XMnPO4F obtained by partially substituting lithium in the sodium position by a chemical process and which has electrochemical activity obtained by improving electrical conductivity by carbon coating.
