Described herein is an electrochemical device including a cathode containing an electroactive material including LOor LO, wherein each L is independently selected from Li, Na, K, Be, Mg, Ca, and Al; the electroactive material is carbon-coated, metal-coated, metal oxide-coated, nano-sized, or doped; and the electroactive material is substantially free of transition metal catalyst.

High capacity lithium ion batteries having oxides, peroxides, or superoxides as cathode active material

A lithium-air battery cathode catalyst includes core-shell nanoparticles on a carbon support, wherein: a core of the core-shell nanoparticles is platinum metal; and a shell of the core-shell nanoparticles is copper metal; wherein: the core-shell nanoparticles have a weight ratio of the copper metal to the platinum metal from about 4% to about 6% copper to from about 2% to about 12% platinum, with a remaining percentage being the carbon support.

Bi-metallic nanoparticles as cathode electrocatalysts

A composition includes LiO, reduced graphene oxide, and a metal catalyst or residue thereof.
