Abstract
A process for the production of a non-aqueous electrolyte battery which comprises a polymer layer forming step of forming a polymer layer on one side of at least one of a positive electrode, a negative electrode and a separator and 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. The process for the production of a non-aqueous electrolyte battery further comprises 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 a heating and cooling step of heating and cooling the non-aqueous electrolyte battery while the battery case is under pressure.
