Abstract: A resonant circuit can be used in recharging a battery. The resonant circuit includes an inductor, a first capacitor in series with the inductor, and a second capacitor in parallel with the inductor. Upon entering the field of a charging terminal a controller connected to the resonant circuit continually measures loss in the inductor and voltage on a terminal of the resonant circuit. If both are below respective predetermined thresholds, the controller decreases the capacitance of the first capacitor and increases the capacitance of the second capacitor, thereby increasing voltage from the resonant circuit to the battery.

Abstract: A battery structure has structure anode and cathode contacts on a front face and on a rear face. The battery structure includes a battery having battery anode and cathode contacts only on a front face thereof. A film including a conductive layer and an insulating layer jackets the battery. The conductive layer extends over the battery anode and cathode contacts and is interrupted therebetween. Openings are provided in the insulating layer on the front and rear faces of the battery structure to form the structure anode and cathode contacts of the battery structure.
