| 摘要 |
The present invention provides a manufacturing method of a non-aqueous electrolyte secondary battery, having high durability. The manufacturing method of a non-aqueous electrolyte secondary battery comprises: preparing a separator substrate (42); forming a porous layer (44), which contains at least fluorophosphate and a binder, on a surface of the separator substrate (42); producing an electrode body (80) by interposing a separator (40) having the porous layer (44), and facing a positive electrode (10) and a negative electrode (20), wherein the separator (40) is arranged so that the porous layer (44) faces the positive electrode (10); producing a battery assembly using the electrode body (80) and a non-aqueous electrolyte; and charging the battery assembly at least once. |
