Title:
POSITIVE ACTIVE MATERIAL FOR LITHIUM ION SECONDARY BATTERY, POSITIVE ELECTRODE MATERIAL, AND LITHIUM ION SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2016/046868
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a lithium ion secondary battery which has a high capacity in both low-rate and high-rate discharges and is reduced in open circuit voltage (OCV) hysteresis arising between the charge and the discharge. The problem can be solved with a positive electrode material comprising: a first positive active material which is a positive active material represented by the empirical formula LixNiaMnbMcO2 (wherein 1.09
