ABSTRACT
In conclusion, the electrochemical
stability of Zn metal anodes in wide-pH electrolytes can be enhanced by the
strategy of electrolyte engineering and electrode design. On one hand, the
optimization mechanism of electrolyte engineering can be considered as the
manipulation of chemical environment at the electrode/electrolyte interface. In
particular, the amphipathic organics-based EDL and fluorinated polymer
interphase can mitigate the wide range of pH and act as a protective layer,
thus ensuring the highly reversible redox conversion of Zn anodes. On the other
hand, the main guideline of electrode design consists in the growth of
zincophilic and hydrogen-inert sites, intending to successfully address the
suboptimal utilization rate of Zn metal over a wide pH range. Although the
above electrolyte additives and electrode alloying strategies have shown
significant results in improving the reversibility of deposition/stripping of
Zn anode in wide pH aqueous electrolytes, there is still a lack of suitable
modification strategies for the development of AZMBs with ultra-high energy
densities, as well as a shortage of synergistic optimization of the cathode materials
for wide pH aqueous electrolytes. In short, this work expounds on the optimization
strategy of zinc-electrolytes and zinc-electrodes compatible with a wide range
of pH, which might be an inspiration in the fields of practical Zn anodes for
the state-of-art AZMBs.
