Title:
CATHODE ACTIVE MATERIAL FOR LITHIUM ION SECONDARY BATTERY AND MANUFACTURING METHOD FOR THE SAME, AND LITHIUM ION SECONDARY BATTERY USING THE SAME
Document Type and Number:
Japanese Patent JP2016004708
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cathode active material for a novel lithium ion secondary battery having higher capacity.SOLUTION: A cathode active material for a lithium ion secondary battery contains particles which mainly contain a lithium-contained transition metal compound having a composition of LiMePO(Me at least partially contains at least one kind of transition metal selected from Mn, Co and Fe), and particles which mainly contain lithium fluoride. The mole ratio of the lithium-contained transition metal compound to lithium fluoride ranges from 0.5 to 2.0.
