High-Performance, Layered, 3D-LiCoO2 Cathodes with a Nanoscale Co3O4 Coating via Chemical Etching

Chemical etching concurrently modifies pristine to layer-by-layer 3D-LiCoO 2 with a Co 3O 4 coating. Not only can the layered morphology affect the high electrochemical performance, but also the coating effect reduces the structure instability of the LiCoO 2 during cycling. This process can be applied to design other compounds to enhance their performance in Li-ion batteries.close6
