Claims20
A battery comprising:
- a metal foil, wherein a coating is disposed on a portion of the metal foil, and wherein an uncoated portion of the metal foil corresponds to an electrode member of the battery;
- and
- a ceramic barrier disposed on at least a portion of a boundary between the electrode member and the coating.
A method of fabrication of a battery, the method comprising:
- forming a coating on a first portion of a metal foil while leaving an uncoated portion of the metal foil to provide an electrode member of the battery, wherein the coating terminates at the uncoated portion and defines a boundary between the electrode member and the coating;
- and
- forming a ceramic barrier disposed on at least a portion of the boundary of the electrode member and the coating.
A battery comprising:
- a metal foil, wherein a coating is disposed on a portion of the metal foil, and wherein an uncoated portion of the metal foil corresponds to an electrode member of the battery;
- a ceramic barrier disposed on at least a portion of a boundary between the electrode member and the coating;
- an anode;
- a cathode;
- and
- a separator, wherein the anode, the cathode, and the separator are disposed in a roll configuration.
