NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

A nonaqueous electrolyte secondary battery according to a present exemplary embodiment comprises an electrode element including a positive electrode and a negative electrode arranged to face each other, a nonaqueous electrolyte and a jacket housing the electrode element and the nonaqueous electrolyte. The negative electrode is formed by bounding a negative electrode active material to a negative electrode collector with a negative electrode binder, the negative electrode active material containing (a) a carbon material capable of intercalating and deintercalating lithium ions, (b) a metal capable of forming an alloy with lithium and (c) a metal oxide capable of intercalating and deintercalating lithium ions. The nonaqueous electrolyte contains a nonaqueous solvent, a cyclic fluorinated carbonate and a linear fluorinated ether.
