CATHODE MATERIAL FOR LITHIUM-OXYGEN BATTERY

摘要

A lithium-oxygen battery may include an anode, a cathode, and an electrolyte between, and in contact with, the anode and the cathode. The anode may include lithium and/or a lithium alloy. In some examples, the cathode defines a surface that is predominantly metal oxide with an electron conductivity of at least 10−1 Siemens per centimeter. In some examples, the cathode defines a surface in contact with oxygen, and includes ruthenium oxide. In some examples, the cathode defines a surface that is substantially covered by ruthenium oxide and is in contact with oxygen.
