NICKEL HYDROXIDE, METHOD FOR MANUFACTURING POSITIVE ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

A positive electrode active material for nonaqueous electrolyte secondary batteries is permitted to contain a lithium-nickel complex oxide by firing a nickel hydroxide having a primary particle average diameter of 1-5mum and a DBP absorption of 10-30mL/100g, and a lithium compound in an oxidizing atmosphere. The lithium-nickel complex oxide has excellent filling characteristics, power characteristics (especially high-rate characteristics), and is effective as a positive electrode active material for nonaqueous electrolyte secondary batteries.
