1. A wireless power receiver configured to receive wirelessly delivered power, the wireless power receiver comprising:

  • at least one battery having at least two battery terminals including a battery positive terminal and a battery negative terminal, and at least a part of the battery is configured to act as an antenna that wirelessly receives radio frequency (RF) power signals;

    power conversion circuitry having at least one connector electrically coupled to at least one of the at least two battery terminals, wherein the power conversion circuitry is configured to convert an alternating current (AC) generated by reception of the RF power signals received at the at least one battery into a direct current (DC) voltage; and

    charging circuitry having at least two charging circuit terminals, including a charging circuit positive terminal electrically coupled to the battery positive terminal via a first inductor, and a charging circuit negative terminal electrically coupled to the battery negative terminal via a second inductor, wherein;

    the first inductor and the second inductor are configured to block the alternating current from being received by the charging circuitry,the charging circuitry is electrically coupled to the power conversion circuitry, andthe charging circuitry is configured to (i) receive the DC voltage from the power conversion circuitry and (ii) charge the at least one battery using the DC voltage.
