Abstract
The invention is a high-performance lithium ion secondary battery which needs no firm case so that it is possible to reduce the size and weight and to design the shape freely and yet which secures high structural strength and safety. The method of the invention for forming a lithium ion battery comprises the step of joining a positive electrode ( ) having a positive electrode active material layer ( ) joined to a positive electrode current collector ( ) and a negative electrode ( ) having a negative electrode active material layer ( ) joined to a negative electrode current collector ( ) with an adhesive resin ( ) comprising at least partially a plastic resin being present in parts therebetween and the step of deforming the adhesive resin ( ). The method achieves simplification and improvement of productivity in forming a lithium ion battery.
