The sluggish lithium diffusion at the electrode/electrolyte interface is one of the main obstacles to achieve superior rate capability of Li metal anodes for rechargeable batteries. WebbSluggish diffusion kinetics Atomic diffusion mechanisms in CCAs is considered sluggish (Yeh et al., 2004 ). The assumption is that diffusion kinetics is generally difficult in concentrated solid solutions than in dilute solutions ( Tsai et al., 2013 ). Webb11 apr. 2024 · Therefore, Na ions transport in the bulk of TSC would be faster than that in pristine TiO2. Considering that SnO2 suffers from more sluggish reaction kinetics than TiO2,31-33 the obvious improvement on sodium ion diffusion coefficient could be attributed to the unique heterogeneous structure. in a pnp transistor the p-region are
