Chemists at the University of Waterloo have identified the key reaction that takes place in sodium-air batteries. Understanding how sodium-oxygen batteries work has implications for developing the more powerful lithium-oxygen battery, which has been proposed by some as the “holy grail” of electrochemical energy storage.

Researchers led by a team from MIT, with colleagues from Oak Ridge National Laboratory (ORNL), BMW Group, and Tokyo Institute of Technology have developed a fundamentally new approach to alter ion mobility and stability against oxidation of lithium ion conductors—a key component of rechargeable batteries—using lattice dynamics.

The problem of these rechargeable batteries’ dwindling capacity was well known. Its lab tests revealed that most were variations of salt mixtures, such as sodium and magnesium sulfates. Once again, tests by the NBS found no difference in performance between batteries treated with additives and the untreated control group.
