Although there are many cathode candidates for sodium-ion batteries (NIBs), NaCrO remains one of the most attractive materials due to its reasonable level of capacity, nearly flat reversible voltages, and high thermal stability. However, the cyclic stability of NaCrO needs to be further improved in order to compete with other state-of-the-art NIB cathodes. In this study, we show that CrO-coated and Al-doped NaCrO, which is synthesized through a simple one-pot synthesis, can achieve unprecedented cyclic stability.

Repeated charge/discharge in aqueous zinc-ion batteries (ZIBs) commonly results in surface corrosion/passivation and dendrite formation on zinc anodes, which is a major challenge for the commercialization of zinc-based batteries. In this work, metallic Zn modified by self-assembled monolayers is described as a viable anode for ZIBs. ω-mercaptoundecanoic acid that is spontaneously adsorbed on Zn (MUDA/Zn) contributes to the simultaneous suppression of side reactions and dendrite formation in ZIBs.
