• Electrochemical impedance studies of capacity fading of electrodeposited ZnO conversion anodes in Li-ion battery

Electrodeposited ZnO coatings suffer severe capacity fading when used as conversion anodes in sealed Li cells. Capacity fading is attributed to (i) the large charge transfer resistance, $R_{\rm ct}$ (300–700 $\Omega$) and (ii) the low Li$^+$ ion diffusion coefficient, D$^+_{\rm Li}$ (10$^{−15}$ to 10$^{−13}$ cm$^2$ s$^{−1}$). The measured value of R$_{\rm ct}$ is nearly 10 times higher and D$^+_{\rm Li}$ 10–100 times lower than the corresponding values for Cu$_2$O, which delivers a stable reversible capacity.
