Abstract
Disclosed herein is a metal-air battery having a cathode, an anode, and an electrolyte. The cathode has a cathode current collector and a composite of a porous carbon structure and a pseudocapacitive coating. The coating does not completely fill or obstruct a majority of the pores, and the pores can be exposed to a gas. The electrolyte is in contact with the anode and permeates the composite without completely filling or obstructing a majority of the pores.
Claims21
A metal-air battery comprising:
- a cathode comprising:
- a cathode current collector;
- and
- a composite comprising a porous carbon structure comprising a surface and pores and a coating on the surface comprising a pseudocapacitive material;
- wherein the coating does not completely fill or obstruct a majority of the pores;
- and
- wherein the battery is configured with the capability to expose the pores to a gas;
- an anode;
- and
- an electrolyte in contact with the anode and permeating the composite without completely filling or obstructing a majority of the pores.
