Nonaqueous electrolyte secondary battery and method for manufacturing the same

Abstract

The present invention provides a positive electrode for a nonaqueous electrolyte secondary battery in which after continuous charge is performed, an increase in battery thickness is suppressed, and a residual capacity rate is increased by reduction in gas generation amount and also provides a method for manufacturing the positive electrode described above. This positive electrode includes a positive electrode collector and a positive electrode active material layer which contains a positive electrode active material and a phosphate salt represented by NaH2PO4 and which is formed on a surface of the positive electrode collector. In addition, on a surface of the positive electrode active material layer, a porous layer containing an inorganic oxide filler is preferably formed.
