Abstract:
A process for the production of a non-aqueous electrolyte battery comprising:(1) a polymer layer forming step of forming a polymer layer on at least one side of at least one of a positive electrode, a negative electrode and a separator; (2) an electricity-generating element preparing step of laminating or winding the positive electrode, the negative electrode and the separator to prepare an electricity-generating element; (3) a battery preparing step of receiving the electricity-generating element in a battery case, injecting an electrolyte into the battery case and then hermetically sealing the battery case to prepare a non-aqueous electrolyte battery; and (4) a heating and cooling step of heating and cooling the non-aqueous electrolyte battery while the battery case is under pressure.
