Abstract

Official abstract text for this publication.

A cylindrical rechargeable battery including a positive electrode, a negative electrode, and a separator is provided. The positive electrode includes a positive electrode tab, and a piezoelectric element and a thermoelectric element are formed at edges of the positive electrode tab.

First claim

Opening claim text (preview).

The invention claimed is: 1. A cylindrical rechargeable battery comprising: a positive electrode, the positive electrode including: a positive electrode tab having a pair of opposed edges; a piezoelectric element at at least one edge of the pair of opposed edges of the positive electrode tab; and a thermoelectric element at the positive electrode tab; a negative electrode; and a separator. 2. The cylindrical rechargeable battery of claim 1 , wherein the positive electrode tab has a rectangular strip shape having a long length in comparison with a width. 3. The cylindrical rechargeable battery of claim 2 , wherein the thermoelectric element is formed at another edge of the pair of opposed edges of the positive electrode tab in a longitudinal direction thereof. 4. The cylindrical rechargeable battery of claim 1 , wherein accommodating spaces in which the piezoelectric element and the thermoelectric element are mountable are formed at the pair of opposed edges of the positive electrode tab. 5. The cylindrical rechargeable battery of claim 4 , wherein the accommodating spaces have a stepped shape. 6. The cylindrical rechargeable battery of claim 1 , wherein the piezoelectric element is formed at both edges of the pair of opposed edges of the positive electrode tab. 7. The cylindrical rechargeable battery of claim 6 , wherein the thermoelectric element is formed at a central portion of the positive electrode tab. 8. The cylindrical rechargeable battery of claim 7 , wherein an indentation is formed into the positive electrode tab. 9. The cylindrical rechargeable battery of claim 8 , wherein the thermoelectric element is accommodated in the indentation. 10. The cylindrical rechargeable battery of claim 1 , wherein electrical energy generated by the piezoelectric element is transferred to the thermoelectric element through the positive electrode tab. 11. A cylindrical rechargeable battery comprising: a positive electrode; a negative electrode, the negative electrode includes including: a negative electrode tab having a pair of opposed edges; a piezoelectric element at at least one edge of the pair of opposed edges of the negative electrode tab; and a thermoelectric element at the negative electrode tab; and a separator.
