Abstract
Official abstract text for this publication.
According to one embodiment, a nonaqueous electrolyte secondary battery includes a nonaqueous electrolytic solution, a positive electrode and a negative electrode is provided. The nonaqueous electrolytic solution comprises a nonaqueous solvent. The nonaqueous solvent comprises from 50 to 95% by volume of a sulfone-based compound represented by the following formula 1: wherein R 1 and R 2 are each an alkyl group having 1 to 6 carbon atoms and satisfy R 1 ≠R 2 . The positive electrode comprises a composite oxide represented by Li 1-x Mn 1.5-y Ni 0.5-z M y+z O 4 . The negative electrode comprises a negative electrode active material being capable of absorbing and releasing lithium at 1 V or more based on a metallic lithium potential.
