14 Claims

1. A method for producing a battery assembly comprising a plurality of non-aqueous electrolyte secondary batteries, the method comprising the steps of:

(1) discontinuously forming a plurality of positive electrode active material layers on an inner surface of a first outer jacket comprising a band-shaped positive electrode current collector except for a peripheral portion of said first outer jacket, thereby producing an assembly of a plurality of positive electrode plates;

(2) forming a negative electrode active material layer on an inner surface of a second outer jacket comprising a sheet-shaped negative electrode current collector except for a peripheral portion of said second outer jacket, thereby producing a negative electrode plate;

(3) integrating into one piece said positive electrode plate and said negative electrode plate, with a separator layer comprising a polymer electrolyte or a starting material thereof interposed between said positive electrode active material layer and said negative electrode active material layer;

(4) bonding a peripheral portion of said positive electrode current collector and a peripheral portion of said negative electrode current collector, which face each other, with an insulating material interposed therebetween; and

(5) bending said battery assembly at portions connecting the batteries in such a manner that current collectors having the same polarity of adjacent batteries face each other.
