Abstract
The invention is directed to chemical batteries employing conductive and/or semiconductive electrode cores that are coated with at least one ceramic coating layer and methods of preparing the same. The batteries and/or battery cells include an electrolyte composition. The ceramic coating layer(s) provides a protective layer for the electrodes to prevent rapid corrosion. The ceramic coatings also serve to control energy and rate of ion exchange between the electrolyte composition and the electrode.
Claims20
A chemical battery comprising:
- at least one cell comprising at least two electrodes, wherein the at least two electrodes comprise an anode and a cathode, and wherein the electrodes have at least one ceramic coating layer comprising a refractory, modifier, metal, and flux.
A battery cell comprising:
- an anode comprising a metal, metal alloy, or ceramic metal glass;
- a cathode comprising a metal, metal alloy, or ceramic metal glass;
- wherein the anode and cathode have at least one ceramic coating layer comprising at least three of a refractory, modifier, metal, and flux.
A method of preparing a battery cell comprising:
- providing conductive or semiconductive electrode cores, wherein said conductive or semiconductive electrode cores include at least one anode and one cathode, and wherein said electrodes comprise a metal, metal alloy, or ceramic metal glass;
- adding at least one ceramic coating layer to each electrode surface, wherein said ceramic coating layer comprises a refractory, modifier, metal, and flux;
- heating the electrode and at least one ceramic coating layer in order to fuse the at least one ceramic coating layer, wherein said ceramic coating layer is resistant to corrosion in an electrolyte environment and controls the rate of ion transfer between an electrolyte and the electrode.
