A Lithium-Air Battery with a High Energy Air Cathode

Completed Technology Project

Project Description

A Lithium-Air Battery with a High Energy Air Cathode
This project will advance an efficient and lightweight energy storage device for Oxygen Concentrators by developing a high specific energy lithium-air cell. Specifically the project advances high specific energy cells by focusing on the catalysts in the cathode and anode protection of our existing cells under various oxygen atmospheres for NASA applications. Our high-energy air cathodes will be improved upon and incorporated into the cell designs. Several different chemically composed air cathodes will be investigated. Lithium-air cells produce power by the lithium reacting with the oxygen in the cathode. The anticipated result of the phase 1 project is a bench top operational cell (TRL4). Advantages of the proposed lithium-air cell include a high energy density, safe and lightweight design, and a high energy density cathode. More »
