Abstract:
1. A method of manufacturing a solid-electrolyte battery comprising: forming a first set of gel-electrolyte layers on both sides of a positive electrode collector; forming a second set of gel-electrolyte layers on both sides of a negative electrode collector; forming a positive electrode comprising the first set of gel-electrolyte layers on both sides of the positive electrode collector; forming a negative electrode comprising the second set of gel-electrolyte layers on both sides of a negative electrode collector; laminating said positive electrode and said negative electrode such that one of the first set of gel-electrolyte layers and one of the second set of gel-electrolyte layers face each other; winding said positive electrode and said negative electrode such that another one of the first set of gel-electrolyte layers and one of the second set of gel-electrolyte layers face each other; sealing the wound electrode in a film pack formed by laminating a nylon layer, an aluminum layer and a polypropylene layer on the wound electrode and welding an outer end of the film pack; and after sealing said wound electrodes into the film pack, subjecting said wound electrodes to heat treatment so that each of the first set of gel-electrode layers and the one of the second set of gel-electrolyte layers facing each other are integrated with each other into one continuous seamless layer by heating the laminated electrode in an atmosphere having a temperature of between 70 and 100 degrees C., wherein,
