Abstract
A method of fabricating a lithium ion secondary battery, wherein a positive electrode,is prepared by bonding a positive electrode active material layer,to a positive electrode collector,, a negative electrode,is prepared by bonding a negative electrode active material layer,to a negative electrode collector,and a separator,which is arranged between these two electrodes and closely adhered thereto by bonding, using a fluoride containing adhesive resin mixed with N-methylpyrrolidone solvent and in which the N-methylpyrrolidone solvent is evaporated to produce through holes, which communicate the positive electrode active material layer,and the negative electrode active material layer,with the separator
