Abstract:
A wireless rechargeable solid-state battery module includes a solid-state battery; an internal structure including an internal circuit electrically connected with the battery; positive and negative electrode terminals, each of which is electrically connected with the solid-state battery, is exposed on an outer surface, and is where the positive or negative electrode terminal can be mounted on an electronic circuit board; barrier layers that entirely or partially contain a conductor and isolate the battery and the internal structure from an outside air environment; and a power receiving terminal electrically connected with an external circuit, which includes a power receiving coil coupled with an external electromagnetic or magnetic field, is electrically connected with the internal circuit, and is in an outside of the barrier layers. The power receiving coil converts the external electromagnetic or magnetic field into electrical energy and supplies current to the internal circuit via the power receiving terminal.
