Cathode Catalysts for Non-Aqueous Lithium-Air Batteries

With expanding demand for high over bar performance batteries, Li over bar air batteries have been in spotlight due to the ultra over bar high theoretical energy density. Although some breakthroughs have been accomplished recently, their commercial level applications are still constrained by intense problems and challenges. Among them, sluggish reaction kinetics is assented as one of the serious issues responsible for unsatisfactory battery performance. Thus, an immense measure of exploration on cathode catalysts has been performed lately to improve the battery performance and facilitate the development. In this work, primary advancement and accomplishments on cathode catalysts for non over bar aqueous Li over bar air batteries have been summarized and comparatively discussed, and the future directions and developments have likewise been proposed.
