Abstract
A method for manufacturing a lithium ion secondary battery comprising preparing a positive electrode ( ) where a positive electrode active material ( ) is joined with a positive electrode collector ( ), a negative electrode ( ) where a negative electrode active material ( ) is joined with a negative electrode collector ( ), and a separator ( ) for retaining the electrolytes including lithium ions, being arranged between the positive electrode ( ) and the negative electrode ( ), the process of supplying adhesive solution applied on the separator with a second solvent different from a first solvent after applying the adhesive resin solution, where adhesive resin ( ) is dissolved in the above first solvent, to the separator ( ), and the process of forming an electrode laminate by sticking the positive electrode ( ) and the negative electrode ( ) to the separator ( ).
