U Waterloo researchers achieve reversible four-electron conversion with lithium-oxygen batteries
By Miles Gopie Scientists from the University of Waterloo have devised several new electrochemical processes which greatly increase the lifespan and stability of lithium-oxygen batteries. On paper, Li-O2 batteries have high energy densities and low weights. However, they also have internal reactions (involving superoxides and peroxides) that slowly corrode its carbon cathodes. The …read more
