Current challenges and routes forward for nonaqueous lithium–air batteries
Non-aqueous lithium-air batteries have garnered considerable research interests over the past decade due to its extremely high theoretical energy densities and potentially low cost. Great advances have been achieved in both the mechanistic understanding of cell reactions and in the development of effective strategies to help realize a practical energy storage device. By drawing attention to reports published mainly within the past 8 years, this review demonstrates an updated mechanistic picture of the lithium peroxide based cell reaction, and highlights key remaining challenges due to the parasitic processes occurring at the reaction product-electrolyte, product-cathode, electrolyte-cathode and electrolyte-anode interfaces. We introduce the fundamental principles and critically evaluate the effectiveness of the important strategies that have been proposed to mitigate issues of the battery, which include the use of solid catalysts, redox mediators, solvating additives for oxygen reaction intermediates and gas separation membranes, etc. Recently established cell chemistries based on the superoxide, hydroxide and oxide phases are also summarized and discussed.

Abstract

Non-aqueous lithium-air batteries have garnered considerable research interests over the past decade due to its extremely high theoretical energy densities and potentially low cost. Great advances have been achieved in both the mechanistic understanding of cell reactions and in the development of effective strategies to help realize a practical energy storage device. By drawing attention to reports published mainly within the past 8 years, this review demonstrates an updated mechanistic picture of the lithium peroxide based cell reaction, and highlights key remaining challenges due to the parasitic processes occurring at the reaction product-electrolyte, product-cathode, electrolyte-cathode and electrolyte-anode interfaces. We introduce the fundamental principles and critically evaluate the effectiveness of the important strategies that have been proposed to mitigate issues of the battery, which include the use of solid catalysts, redox mediators, solvating additives for oxygen reaction intermediates and gas separation membranes, etc. Recently established cell chemistries based on the superoxide, hydroxide and oxide phases are also summarized and discussed.
