Abstract
Additive‐free nanoscale LiCoO2 thin‐films deposited on Si substrates using DC sputtering show exceptional electrochemical performance due to the unique kinetics of the nanoscale thin‐film in aqueous environment. At extremely high scan rates and galvanostatic current densities of up to 100 mV s−1 and 200 C respectively, a capacity retention equivalent to 97 mAh g−1 (4.8 μAh cm−2, 48.3 μAh cm−2 μm−1) is obtained. A significant contribution of non‐diffusion controlled kinetics in a LiCoO2 electrode is shown.
