“…The current electrolyte additive works have made great progress but mainly focused on changing Zn solvation sheath, forming SEI layers, lowering desolvation energy and guiding deposited preferable Zn lattice planes. [ 16b , 21 ] pH changes in the electrolyte and methods to control stable electrode‐electrolyte interphases in AZBs still need to be well conducted by properly selecting and understanding pH buffer additives.…”

“…This situation became more severe for Zn anodes cycled at a higher temperature of 100 °C. [ 8–10 ] In contrast, the Zn anodes cycled in the TRHE exhibited much smoother morphologies at high temperatures. Furthermore, the in situ optical images of the Zn deposition in BE at high temperatures implied faster dendrite growth and more drastic hydrogen bubble evolution (Figure 5h), indicating significantly accelerated side reactions between the electrolyte and electrode in the aqueous electrolyte.…”

“…Under abuse conditions, such as sudden temperature increase, mechanical shock, or electrical abuse (overcharging or short-circuiting), extreme heat is accumulated inside ZIBs, which inevitably causes thermal runway risk, [5,6] resulting in various problems from the viewpoint of safety (swelling or even explosion by generated hydrogen or steam), electrode stability, and battery system. [7][8][9][10] Although the safety issues caused by thermal runaway in ZIBs are not comparable to those in LIBs using organic electrolytes, the problem still exists in ZIBs. The fast volatilization of water and increase in the internal pressure leads to drastic bulges of batteries and even explosions.…”

“…At low temperatures, electrolyte and anode side issues pose more serious challenges at the electrode/electrolyte interface, including electrolyte freezing, Zn dendrite formation, and side reactions, which are the main factors limiting the cycle life of aqueous ZIBs. [ 192 ] In addition, the kinetics become sluggish at low temperatures, which brings about restricted Zn 2+ migration in the interfacial layer. By designing multifunctional electrolytes, multiple modulations can be achieved, including lowering the freezing point and forming in situ artificial interfaces.…”
