Lithium ion secondary battery and manufacture thereof |
摘要 |
A practical lithium ion secondary battery. The battery is light in weight and is safe without using a firm battery case. It also has reduced internal resistivity. The battery includes a tabular roll-type laminated electrode body in which a band-formed positive electrode alternates with a band-formed negative electrode, with a band-formed rolled separator being placed therebetween. The positive electrode includes a positive electrode active material layer and a positive electrode current collector. The negative electrode includes a negative electrode active material layer and a negative electrode current collector. The separator holds a lithium ion-containing electrolytic solution. The positive electrode or the negative electrode is adhered with two separators by an adhesive layer.
