Semi‐Immobilized Ionic Liquid Regulator with Fast Kinetics toward Highly Stable Zinc Anode under −35 to 60 °C

Aqueous zinc ion batteries (ZIBs) have been extensively investigated as a next‐generation energy storage system due to their high safety and low cost. However, the critical issues of irregular dendrite growth and intricate side reactions severely restrict the further industrialization of ZIBs. Here, a strategy to fabricate a semi‐immobilized ionic liquid interface layer is proposed to protect the Zn anode over a wide temperature range from −35 to 60 °C. The immobilized SiO2@cation can form high conjugate racks that can regulate the Zn2+ concentration gradient and self‐polarizing electric field to guarantee uniform nucleation and planar deposition; the free anions of the ILs can weaken the hydrogen bonds of the water to promote rapid Zn2+ desolvation and accelerate ion‐transport kinetics simultaneously. Because of these unique advantages, the cycling performance of the symmetric Zn batteries is greatly enhanced, evidenced by a cycling life of 1800 h at 20 mA cm−2, and a cycle lifespan of 2000 h under a wide temperature window from −35 to 60 °C. The efficiency of this semi‐immobilizing strategy is well demonstrated in various full cells including pouch cells, showing high performance at large current (20 A g−1) and wide temperatures with extra‐long cycles up to 80 000 cycles.

“…Generally, the lower the T Zn2+ , the larger the concentration gradient of zinc ions on the surface of zinc anode, resulting in grievous surface electric field distribution and dendrite growth. [ 37,38 ] And this situation will become more and more serious with the increase of current density. Therefore, the obvious increase of T Zn2+ in the CF‐Cu symmetrical cell means that the CF layer can effectively eliminate the zinc ion concentration gradient on the electrode surface, inhibit the dendrite growth and improve the Zn 2+ transfer kinetics.…”

Building an artificial interphase layer for tackling uncontrollable Zn dendrites and serious side reactions is a highly desirable strategy, but it is often hampered by the limited Zn 2+ transport. Here, a stable fluorine-doped amorphous carbon (CF) artificial layer is constructed on a Cu current collector (CF-Cu) via facile carbonization treatment of a fluoropolymer coating to realize underlying Zn deposition. As evidenced experimentally and theoretically, this inorganic CF layer with ionic conductivity and electronic insulation successfully triggers dendrite-free Zn deposition at the CF-Cu interface with preferred Zn(002) crystal plane stacking parallel to the substrate surface, thus greatly promoting the inhibition of Zn-dendrites and blocking of interfacial side reactions. The introduced fluorine atoms as abundant zincophilic sites play an important role in driving fast zinc-ion transfer kinetics, which can partly convert into ZnF 2 as an artificial solid Zn 2+ conductor to further guide uniform Zn deposition. Consequently, the CF-Cu electrode enables high reversibility with 99% coulombic efficiency and a long cycling stability of 1900 cycles at 2 mA cm -2 . The integrated CF-Cu@Zn anode achieves up to 2200 h cycles with a low voltage polarization. This study provides inspiration for the design of artificial interphase layers for stable nondendritic metal batteries.

“…More importantly, such DIE separator modified cells enable performing ultrahigh cumulative capacities reaching up to 8000 and even 9500 mAh cm −2 , not only many times higher than that of the unmodified one (Figure 2d), but also much superior to many other previous reports (Figure 2c). [23,25,31,[35][36][37][38][39][40] To reveal the mechanism behind them, Brunner-Emmet-Teller test (Figure S14, Supporting Information) was first performed to explore the decoration of BTO nanoparticles on influencing the pore size structure of separator. The results reveal that the GF and DIE separator exhibit similar surface area of 2.1 and 1.7 m 2 g −1 , respectively.…”

Sluggish transport kinetics and rapid dendrite growth are considered the main obstacles that impair the performance of Zn metal batteries. This work has developed a unique strategy of dual‐interface engineering (DIE) to design the separator as efficient ions transport modulator. The dual function of spontaneous polarization effect and high zincophilicity of BaTiO3 (BTO) is revealed by combining the theoretical and experimental studies. Benefiting from the decoration of BTO on glass fiber and well filling of the surface interspace, the DIE‐modified separator can not only effectively capture and accelerate Zn2+ transport between the fiber–electrolyte interface, but also redistribute the ions transport into homogenization in the separator–anode interface. Therefore, the modified Zn anodes perform highly reversible Zn plating/stripping with ultrahigh cumulative capacity even up to 9500 mAh cm−2 at the high current density of 10 mA cm−2. Meanwhile, the modified Zn‐MnO2 battery can retain a specific capacity of 108 mAh g−1 after 1800 cycles at 1 A g−1. Furthermore, the capacity retention of the battery also can be improved from 37.5% up to 115% at 0.2 A g−1 after 100 cycles. Such a novel concept for separator engineering provides a new perspective to enable ultra‐stable Zn metal anodes and high‐performance Zn metal batteries.
