Sulfide compounds are interesting conversion electrode materials for Li-ion batteries, due to their high theoretical capacity. However, they suffer from large volumetric changes and fast capacity fading.
Finally, the thickness of the Zn electrode progressively decreases with the number of cycles: this process corresponds to anode unbalancing and capacity fade, and is due to the formation of dead metal, caused by the detachment of mossy structures, and insoluble ZnO precipitates in the bulk of the electrolyte.
The slight morphological differences in the pristine state are due to the intrinsic variability of the electrodeposition process adopted for the growth of the Zn electrodes (see Section S2 of the Supporting Information for more details).
A characteristic feature of the inner Zn electrode cycled in the additive-free electrolyte is that, in some areas, a crust is found to form, which covers the original deposit leaving a cavity between the two (Figure 14B ).
The electrochemical and physical properties of sulfide electrolytes used for lithium (Li) metal and particle-type anode materials are presented, as well as strategies for mitigating interfacial failures in solid-state cells through interlayer and electrode design.
Owing to its low electrochemical potential and high theoretical capacity, Li metal is considered to be the most promising anode material for high-energy-density batteries. Nevertheless, the growth of Li dendrites results in serious stability and safety issues.
