“…Herein, inspired by the low-dimensional geometric surface of MXene contributing chemical binding sites, MXene is introduced into DESs as the nucleation additive to crystallize into a solid at room temperature. − The rich Lewis acid center on MXene can strongly interact with the anion of the OTF – , release positively charged zinc ions, and then improve the ionic conductivity of the eutectic solid electrolyte, obtaining highly efficient zinc-ion transport. Moreover, it helps to establish more interfacial ionic conduction pathways through interactions, increasing the ionic conductivity of ZCEs to 6.69 × 10 –4 S cm –1 .…”

Stationary energy storage infrastructure based on zinc-ion transport and storage chemistry is attracting more attention due to favorable metrics, including cost, safety, and recycling feasibility. However, splitting water and liquid electrolyte fluidity lead to cathode dissolution and Zn corrosion, resulting in rapid attenuation of the capacity and service life. Herein, a new architecture of solid-state electrolytes with high zinc ionic conductivity at room temperature was prepared via solidification of deep eutectic solvents utilizing MXene as nucleation additives. The ionic conductivity of MXene/ZCEs reached 6.69 × 10 −4 S cm −1 at room temperature. Dendrite-free Zn plating/stripping with high reversibility can remain for over 2500 h. Subsequently, the fabricated solid-state zinc-ion battery with eliminated HER and suppressed Zn dendrites exhibited excellent cycling performance and could work normally in a range from −10 to 60 °C. This design inspired by eutectic solidification affords new insights into the multivalent solid electrochemistry suffering from slow ion migration.

Rechargeable alkaline Zn–Cu batteries show great potential for energy storage systems due to their high capacity, cost‐effectiveness, and environmental‐friendliness. However, restricted by the severe dissolution upon charging, rapid capacity decline occurs throughout the cycle. Herein, the charging protocol is adjusted to bypass the dissolution stage of high‐valent states, thereby preserving the optimal reaction section of Zn–Cu batteries and greatly improving cycling stability. Additionally, a self‐activation process in the initial stage led to the spontaneous transformation of the original electroplated Cu particles on nickel foam from 10 to 4 mm, enhancing both conductivity and mass transfer, ultimately increasing the utilization of active materials. The battery achieved a discharge capacity of 349.5 mAh g−1, an ultra‐flat charge–discharge voltage platform, over 92% energy efficiency, a low cost of only $43.25 per kWh, and an exceptionally stable cyclic performance with no noticeable decay over 400 cycles. These 5D improvements position the Cu electrode as a robust candidate for the positive electrode material in the next generation of commercial Zn batteries.
