Abstract
A novel approach is proposed for the development of safe lithium-air batteries that offer high-energy storage capacity and extended standby and operational life. The proposed battery will use a lithium anode, an air cathode having an air stable non-volatile electrolyte and a multilayer polymer electrolyte/glass electrolyte barrier to protect the lithium anode from direct reactions with water and oxygen from the atmosphere. Since there will be no volatile liquid electrolyte, safety performance of the lithium-air battery will be enhanced. The areas to be studied include the ionic conductivity of the polymer electrolyte, as well as the interface between lithium metal and polymer electrolyte, and the moisture absorption behavior of the air electrode. In Phase II we will investigate the performance of the whole battery system and battery structure to produce an all solid state lithium oxygen battery.
