发明名称 NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
摘要 Provided is a non-aqueous secondary battery that uses a lithium-containing metal oxide that contains manganese as a positive electrode active material, and wherein a small internal resistance and a high electric capacity can be maintained even after high-temperature storage or charge and discharge at high temperatures, by suppressing elution of manganese from the positive electrode active material. Specifically provided is a non-aqueous electrolyte secondary battery with a negative electrode capable of intercalating and deintercalating lithium ions, a positive electrode with a lithium-containing compound as the positive electrode active material, and a non-aqueous electrolyte that has lithium salt dissolved in an organic solvent. Said non-aqueous electrolyte secondary battery is characterized by the lithium-containing compound being a lithium-containing metal oxide compound that contains manganese and by the non-aqueous electrolyte containing a fluorosilane compound indicated by general formula (1). (In the formula, R1 to R3 independently represent an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms, an aryl group having 6 to 8 carbon atoms, or a fluorine atom, and R4 represents an alkylene group having 1 to 8 carbon atoms or an alkylene group having 4 to 8 carbon atoms and having an ether group.)
