Document Type and Number:
WIPO Patent Application WO/2014/147983
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a non-aqueous electrolyte secondary battery that suppresses the oxidative decomposition of an electrolytic solution in a high-temperature environment, and for which high temperature storage characteristics and cycle characteristics are dramatically improved. This non-aqueous electrolyte secondary battery is provided with a positive electrode plate having a positive electrode active material, a negative electrode plate having a negative electrode material, and a non-aqueous electrolyte, and is characterized by the following: the positive electrode active material is a lithium transition metal composite oxide; on the surface of the positive electrode active material there is one type of rare earth hydroxide and/or rare earth oxyhydroxide; and the non-aqueous electrolyte includes fluoroarene.
