“…Alternatively, Zn is cost-effective, nontoxic, soluble in solvents with higher pH, and color-neutral and has high theoretical CE (59 cm 2 C 1– ) . Zn-RME is thus deemed to be an optimal platform for safe, cost-effective, and color-neutral ESWs. , An initial attempt of ECD assembly via Zn-RME is unsatisfactory due to the poor cyclic stability, low optical modulation range, and non-neutral color conversion . During Zn plating, the randomly formed Zn nuclei in the early stage will evolve into protrusions under the Zn 2+ concentration gradient, accelerating accumulated growth at the tips and gradually forming difficult-to-dissolve Zn dendrites.…”

Reversible metal electrodeposition (RME)-based smart windows can realize large solar heat gain coefficient (SHGC) modulation, where Zn-RME emerges as an intriguing option with high theoretical coloration efficiency (CE), cost effectiveness, and color neutrality. Herein, Cu 2+ was selected as electrolyte additive to lower the activation energy and homogenize the electrical field distribution during metal plating, forming gradient CuZn alloy nanoparticles via reversible alloy electrodeposition (RAE). Compared to Zn-RME, the CuZn-RAE electrode can achieve extremely low transmittance (0.01%) and color neutrality (chroma C* = 5.8) within 2 min, large transmittance modulation (82%), fast switching times (t c = 8 s, t b = 18 s), higher CE, elevated memory effect, and extended cycling stability. Additionally, a tinted CuZn-RAE device can effectively block infrared heat and reduce surface temperature by 7.1 °C, and the insulating glass unit (IGU) modeled with a CuZn-RAE device offers large solar heat modulation with ΔSHGC of 0.448, showing great application potential toward dynamic smart windows.

The emerging concept of weakly solvating electrolytes in multivalent ion aqueous batteries has garnered attention due to their enhanced kinetic performance at a low cost. This article aims to dissect the concept of “weakly solvating electrolyte” into three revelations, i. e., ion solvation, hydrogen bonding strength, and ionic interactions. It is revealed that a weakly interacting solvent must satisfy the requirements of having a solvation strength weaker than water molecules, as well as disrupting rather than strengthening hydrogen bonding within them. Moreover, electrolyte chemistry requires balancing multiple factors, and one weakly interacting solvent can exhibit varying effects with different anions of zinc salts. This study offers quantitative descriptors to the concept of weak solvation, particularly for aqueous electrolytes, and provides insights for future electrolyte advancements for multivalent ion batteries.
