Original Abstract Submitted
A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The positive electrode includes a positive electrode active material layer containing a positive electrode active material. The positive electrode active material includes a lithium nickel cobalt manganese composite oxide. In the composite oxide, a molar ratio of Ni to all metal elements except for Li is 40 to 60 mol %, and a molar ratio of Co to all the metal elements except for Li is 15 to 25 mol %. The composite oxide is in a form of hollow particles each including a shell portion, a hollow portion, and a through hole penetrating the shell portion. The composite oxide has a BET specific surface area of 3.0 m/g or more. The nonaqueous electrolyte contains an electrolyte salt, lithium bis(oxalato)borate, and a nonaqueous solvent that contains a carboxylate ester having 4 or less carbon atoms.
