Abstract:
1. A battery assembly comprising a plurality of non-aqueous electrolyte secondary batteries, each non-aqueous electrolyte secondary battery comprising: a positive electrode plate including an outer jacket comprising a sheet-shaped positive electrode current collector and a positive electrode active material layer formed on an inner surface of said outer jacket except for a peripheral portion thereof; a negative electrode plate including an outer jacket comprising a sheet-shaped negative electrode current collector and a negative electrode active material layer formed on an inner surface of said outer jacket except for a peripheral portion thereof; and a separator layer comprising a polymer electrolyte interposed between said positive electrode active material layer and said negative electrode active material layer, wherein a peripheral portion of said positive electrode current collector and a peripheral portion of said negative electrode current collector are bonded together with an insulating material interposed therebetween, wherein at least one of a plurality of positive electrode plates and a plurality of negative electrode plates constituting said battery assembly forms an electrode plate assembly including an outer jacket comprising a band-shaped current collector and a plurality of active material layers discontinuously formed on an inner surface of said outer jacket except for a peripheral portion thereof, and wherein said battery assembly is bent at portions connecting the batteries in such a manner that current collectors having the same polarity of adjacent batteries face each other.
