Abstract

A method of manufacturing a nonaqueous electrolyte secondary battery includes: preparing a separator substrate (42); forming a porous layer (44), which contains at least a fluorophosphate and a binder, on a surface of the separator substrate (42); preparing an electrode body (80) by laminating a positive electrode (10) and a negative electrode (20) to face each other with a separator (40) including the porous layer (44) interposed therebetween, in which the separator (40) is arranged such that the porous layer (44) faces the positive electrode (10); preparing a battery assembly including the electrode body (80) and a nonaqueous electrolyte; and charging the battery assembly at least once.
