Rechargeable aqueous zinc-ion batteries (AZIBs) have emerged as a promising option for cost-effective and safe energy storage systems owing to the natural abundance of Zn, the use of aqueous electrolytes, the significant theoretical capacity of Zn metal, and their low negative potential. However, the electrolyte instability, dendrite formation, and risk of short circuits within these batteries hinder the efficient utilization of Zn. To address these, in this study, we fabricated a predominant β-phase poly(vinylidene fluoride) (PVDF) using both thermal annealing and an ion−dipole interaction mechanism. Thereafter, the obtained PVDF was utilized as a protective layer for the Zn anode of the AZIBs. The predominant β-phase PVDF-coated Zn (PBP@Zn) anode demonstrated exceptional performance, with a minimal overvoltage of 52 mV during 400 h of operation in symmetrical cell tests. Furthermore, the ZIBs exhibited increased capacity (259 mAh g −1 at 0.3 A g −1 ) and rate capability (100 mAh g −1 at 2.0 A g −1 ), while maintaining remarkable cycling stability. The remarkably enhanced cycling stability demonstrated by PBP@Zn underscores the robust reliability of AZIBs, making them highly suitable for real-world applications.

“…Green energy utilization, storage, and conversion, which are closely related to sustainable societal development and play key roles in the overall energy balance, − require the development of efficient energy storage and conversion technologies. − To that end, supercapacitors have been widely studied because they exhibit high power densities and good cycling performance, , are safe to operate, and have low environmental impact. , These attributes represent distinct advantages that promote their utilization. − However, supercapacitors exhibit unsuitable low energy densities. Compared to lithium-ion batteries as a competing energy-storage technology, supercapacitors have two main disadvantages: − (1) low energy densities (≤15 Wh kg –1 ), equivalent to approximately 5% of that exhibited by typical lithium-ion batteries, and (2) high costs, i.e., approximately 20 times more expensive per unit energy density than lithium-ion batteries.…”

Aqueous zinc-ion hybrid supercapacitors (ZHSCs) have attracted considerable attention because they are inexpensive and safe. However, the inadequate energy densities, power densities, and cycling performance of current ZHSC energystorage devices are impediments that need to be overcome to enable the further development and commercialization of this technology. To address these issues, in this study, we prepared carbon-based ZHSCs using a series of porous carbon materials derived from Sanhua liquor lees (SLPCs). Among them, the best performance was observed for SLPC-A13, which exhibited excellent properties and a high-surface-area structure (2667 m 2 g −1 ) with abundant micropores. The Zn//SLPC-A13 device was assembled by using 2 mol L −1 ZnSO 4 , SLPC-A13, and Zn foil as the electrolyte, cathode, and anode, respectively. The Zn//SLPC-A13 device delivered an ultrahigh energy density of 137 Wh kg −1 at a power density of 462 W kg −1 . Remarkably, Zn//SLPC-A13 retained 100% of its specific capacitance after 120,000 cycles of longterm charge/discharge testing, with 62% retained after 250,000 cycles. This outstanding performance is primarily attributed to the SLPC-A13 carbon material, which promotes the rapid adsorption and desorption of ions, and the charge−discharge process, which roughens the Zn anode in a manner that improves reversible Zn-ion plating/stripping efficiency. This study provides ideas for the preparation of ZHSC cathode materials.

Aqueous zinc-ion batteries (AZIBs) are promising candidates for next-generation electrochemical energy storage systems owing to their abundant resources, high safety, great theoretical capacity, and environmental friendliness. Nonetheless, instability of Zn metal anodes caused by Zn dendrites and various side reactions poses a challenge to their practical feasibility. Optimizing the crystallographic orientation of the Zn metal anodes is demonstrated as a potential approach for solving these issues of AZIBs. Herein, we report an electrodeposition strategy to manipulate the exposure of the preferred (002) crystal planes in the artificial interface layer on Zn foil via adjustment of the electrodeposition current density and time. The (002)oriented Zn metal anodes with an impressive 97.55% relative texture coefficient (RTC) value of (002) and ultrahigh I (002) /I (100) ratio of 310.23 were achieved through electrodeposition at a moderate current density of 30 mA cm −2 and electrodeposition time of 30 min, applicable to large-scale industrial production. The enhanced wettability of the designed (002) Zn@Zn anodes in electrolytes along with the low charge transfer resistance facilitates the migration of Zn 2+ and guides the uniform Zn deposition, thereby inhibiting the dendrite growth and byproduct formation and promoting fast kinetics. In comparison to (101)-oriented pure Zn, the symmetric cell based on (002) Zn@Zn anodes exhibits ultrastable cycling for 3200 h at 1.0 mA cm −2 , and the half-cell presents an average coulombic efficiency of 99.76% throughout the entire 3000 cycles at 5.0 mA cm −2 . The full cell with a bismuth-doped manganese dioxide cathode exhibits an ultrastable cycling performance over 3500 cycles even at 10 C. This work proposes a strategy to regulate the preferred orientation of high-performance Zn anodes for advanced AZIBs.
