Abstract
An easier method is provided for producing a battery comprising an oxalato complex-derived coating on the negative electrode. This invention provides a method for producing a non-aqueous secondary battery, the method comprising: preparing a negative electrode paste comprising a negative electrode active material, a binder, and a polycarboxylic acid-based gas formation inhibitor; fabricating a negative electrode by applying the negative electrode paste to a negative current collector surface; constructing an assembly with a positive electrode, the negative electrode, and a non-aqueous electrolyte solution comprising an oxalato complex; and subjecting the assembly to activation thereby to decompose the oxalato complex and forming a coating derived from the oxalato complex on the negative electrode surface while inhibiting gas formation with the gas formation inhibitor.
