Abstract
A secondary battery having a positive electrode, a negative electrode, and a separator that is arranged between the two electrodes. A porous adhesive resin layer has through holes and the resin layer is formed between the separator and one of the positive electrode and the negative electrode to bond the separator to the one of positive and negative electrodes.
Claims7
A secondary battery comprising:
- a positive electrode having a positive electrode collector and a positive electrode active material layer formed on said positive electrode collector;
- a negative electrode having a negative electrode collector and a negative electrode active material layer formed on said negative electrode collector;
- a separator which is arranged between said positive electrode and negative electrode and is impregnated with electrolytic materials;
- and
- a porous adhesive resin layer having through holes, impregnated with electrolyte materials, and disposed between the separator and one of said positive electrode and said negative electrode so as to bond the separator to said one of positive and negative electrodes.
