Windable Lithium-ion Conducting Ceramic Electrolytes

Lithium-air battery consists of a lithium anode electrochemically coupled to atmospheric oxygen through an air cathode. The major advantages of lithium air batteries are that air cathode active material, oxygen, is not stored internal to cell system and lithium anode being extremely lightweight metal with a highest theoretical specific energy density. This energy density is well comparable with that of gasoline device. This energy density is 10 times higher than the highest energy density for presently available commercial lithium-ion batteries. In addition to these advantages, the lithium air batteries can offer a flat discharge voltage profile, environmental friendliness, and long storage life. Lithium air battery can also be fabricated either in chargeable or non-chargeable modes. These features identify the lithium air batteries as the potential power sources for the portable electronic devices, electric vehicles, and defense applications. In this proposed research, we plan to develop windable electrolyte membrane starting from nanosized LiM2(PO4)3 type powder. Testing cell of lithium-air battery will be constructed and characterized in Phase I.
