Abstract
A nonaqueous electrolyte secondary battery includes a prismatic housing having an opening and a sealing member sealing the opening. The prismatic housing contains a flat-wound electrode assembly and a nonaqueous electrolyte. The flat-wound electrode assembly includes a positive electrode and a negative electrode. The positive electrode includes a positive electrode substrate and a positive electrode active material mixture layer formed on the positive electrode substrate. The positive electrode active material mixture layer contains lithium carbonate and lithium phosphate. The nonaqueous electrolyte contains lithium fluorosulfonate.
