Posted on September 15, 2016 by Amanda Staller
[font size=3]Lithium-air batteries are viewed by many as a potential next-generation technology in energy storage. With the highest theoretical energy density of all battery devices, Li-air could revolutionize everything from electric vehicles to large-scale grid storage. However, the relatively young technology has a few barriers to overcome before it can be applied. A new study published in the Journal of The Electrochemical Society (JES) is taking a fundamental step forward in advancing Li-air through the development of mixed metal catalyst that could lead to more efficient electrode reactions in the battery.
The paper, entitled “In Situ Formed Layered-Layered Metal Oxide as Bifunctional Catalyst for Li-Air Batteries,” details a cathode catalyst composed of three transition metals (manganese, nickel, and cobalt), which can create the right oxidation state during the battery cycling to enable both the catalysis of the charge and the discharge reaction.

[font size=4]Li-ion vs. Li-air[/font]
Li-air technology has become a highly researched area due to the technical limits of the maturing Li-ion battery. In order to achieve high-energy dense applications, such as electric vehicles that can exceed 300 miles on a single charge, efforts have been placed in potential breakthrough technologies such as Li-air.
Abraham, who published the first work on non-aqueous Li-air batteries in 1996 in an article in JES entitled, “A Polymer Electrolyte-Based Rechargeable Lithium/Oxygen Battery,” has witnessed this field transform tremendously over the past 10 years.
