Abstract
A battery includes a case, at least one of a first battery cell and a second battery cell disposed in the case, and a graphite sheet disposed at at least one of a position between the case and the first battery cell and a position between the first battery cell and the second battery cell. The graphite sheet has a terminal portion for taking out an electrical signal.
Claims15
A battery comprising:
- a case;
- a first battery cell disposed in the case;
- and
- a capacitor portion disposed between the case and the first battery cell,
- wherein the capacitor portion includes:
- a graphite sheet disposed between the case and the first battery cell;
- and
- a dielectric layer disposed between the graphite sheet and the case;
- wherein the case includes a conductive inner surface facing the dielectric layer, and
- wherein the graphite sheet includes a terminal portion which outputs an electrical signal that indicates a capacitance between the conductive inner surface and the graphite sheet.
