Inductive rechargeable energy storage device

摘要

An inductive chargeable energy storage device 10 comprises an energy storage unit 11 and a diode 12. The energy storage unit includes a positive electrode spiral coil 21 on one side of an insulating substrate, a negative electrode spiral coil 31 on one side of another insulating substrate and a separator between the positive and negative electrode spiral coils. The positive coil, the diode and the negative coil are connected in series to form an inductive chargeable energy storage circuit. When the circuit is coupled to a primary or transmitter circuit 41 of an inductive charging platform, the conductors of the positive and negative coils receive electric energy inductively or wirelessly from the primary or transmitter coil 42, convert the electric energy to DC, so that the received electric energy is stored in the positive and negative electrode spiral coils as charges, chemical energy or any combination thereof.
