Effect of calcium or yttrium doping on cation ordering and electrochemical performance of Li(Ni0.80−xCo0.15Al0.05Mx)O2 (M = Ca, Y) as a Li-ion battery cathode
An SnO2-carbon nanocomposite was created by a self-assembly method. This showed promising electrochemical performance as both a Na and Li ion battery anode, with among the best cyclability and rate capability when tested against Na.
