Thin cathode for micro-battery

Abstract:

Batteries include an anode, an electrolyte having a high solubility for lithium ions and oxygen, and a cathode formed on a substrate. Lithium ions migrate from the anode through the electrolyte to form Li.sub.2O.sub.2 at a surface of the cathode. A current collector positioned in the electrolyte, the electrolyte separating the anode from the cathode.
