RAW MATERIAL HYDROXIDE FOR LITHIUM ION BATTERY POSITIVE ELECTRODE MATERIAL AND LITHIUM ION BATTERY POSITIVE ELECTRODE MATERIAL USING SAME

摘要

PPROBLEM TO BE SOLVED: To provide a raw material hydroxide for a lithium ion battery positive electrode material having a high tap density, and to provide a lithium ion battery electrode material using the raw material hydroxide for a lithium ion battery positive electrode material. PSOLUTION: The raw material hydroxide for a lithium ion battery positive electrode material is represented by a composition formula: (Ni1-x-y-z, Cox, Mny, Mz)(OH)SB2/SB(or including M=Al, Mg, Ti in some cases) and is used for a raw material of a lithium ion battery positive electrode material which has a tap density of 1.0g/cmSP3/SPor higher, and is represented by a composition formula: Li1+a(Ni1-x-y-z, Cox, Mny, Mz)1-aOSB2/SB(or including M= Al, Mg, Ti in some cases).
