V at different scan rates from 0.1 to 2 mV s -1 (Figs. and). This is one of the effective approaches to investigate the electrochemical reaction kinetics of electrode materials for Li + storage . A recent study revealed that the capacity generation of a silicate glass-ceramic anode involves two lithium-ion storage mechanisms . One is the lithium insertion reaction, while the other is related to both ion diffusion and surface induced capacitance. In the present work, we determine the degree of surface induced capacitive effect of the studied anodes using the relationship between the measured current (i) and sweep rate (v) of the CV curves, i.e., i = av b , where a and b are adjustable parameters.
