Abstract
A method of making a battery having a cathode includes contacting carbon particles with an oxidizing agent, such as, for example, an inorganic acid, an organic acid, or an oxidizing gas, and incorporating the carbon particles into the cathode. The cathode can be used, for example, in a metal-air battery that includes a monolayer or dual-layer cathode, or in a fuel cell.
