Chemical synthesis and steady state characterization of a nanocrystalline lithium cobalt oxide

Lithium cobalt oxide (LiCoO2 ) is one of the most relevant components in lithium-ion batteries. The array of sought-after features of LiCoO2 depends on its synthesis method. In this work we synthesized and characterized a nanocrystalline LiCoO2 oxide obtained with a wet chemistry synthesis met...
