Abstract
A non-aqueous electrolyte battery using a lithium-containing metal oxide containing manganese as a positive electrode active material, which can suppress the elution of manganese from the positive electrode active material. The non-aqueous electrolyte secondary battery has a negative electrode capable of intercalating and deintercalating lithium ions, a positive electrode containing a lithium-containing compound as a positive electrode active material, and a non-aqueous electrolyte in which a lithium salt is dissolved in an organic solvent. The lithium-containing compound is a lithium-containing metal oxide containing manganese, and the non-aqueous electrolyte contains a fluorosilane compound: Rto Reach represents a 1-8 carbon alkyl group, a 2-8 carbon alkenyl group, a 5-8 carbon cycloalkyl group, a 6-8 carbon aryl group or a fluorine atom, and Rrepresents a 1-8 carbon alkylene group or a 4-8 carbon alkylene group having an ether group.
