Abstract
A battery using porous polymer materials with tapered or cone-shaped metalized pores. The types of batteries include, but are not limited to, Li—CoO2, Li—Mn2O4, Li—FePO4, Li—S, Li—O2, and other lithium cathode chemistries. The tapered metalized pores contain lithium metal in small reaction zones in the anode and cathode in a flexible structure. The form factor of such assembly would be very thin. Because of the thin form factor these electrodes would be suitable for batteries that require high power density, such certain electrical vehicles, power tools, and wearable devices.

An anode comprising:
- a porous polymer anode base material having a cathode facing surface, an anode backside surface, and pores with internal anode pore walls;
- and
- a coating of conductive material on said anode backside surface, and on said internal anode pore walls;
- a passivation layer on the said cathode facing surface;
- said internal anode pore walls have a proximate end, proximal to the cathode facing surface and a distal end, proximal to the anode backside surface;
- the said coating of conductive material applied to the internal anode pore walls is tapered to be thicker at the said distal end than the proximate end.
