“…The ZIHC directly utilizes Zn foil as the battery-type electrode, which possesses a high theoretical capacity (̃819 mAh g –1 or 5854 mAh cm –3 ), excellent electrical conductivity, and suitable redox potential (−0.76 V versus the standard hydrogen electrode). − Carbon materials are the most studied capacitor-type electrodes; however, they are limited by their relatively low capacitance. Though tremendous efforts have been devoted to improving the performance of carbon electrodes through strategies including morphological regulation and ionic doping, etc., − the capacitance enhancement cannot meet the ever-increasing demand. Alternatively, transition metal nitrides are attractive candidates due to their excellent electrochemical performance and stability in mild electrolytes. ,, In this regard, combining Zn and transition metal nitrides is expected to result in high-performance ZIHCs.…”

“…TiN has been widely explored for electrochemical energy storage applications given its high electrical conductivity (27 μΩ cm –1 ) and robust chemical/electrochemical stability. , However, the capacitance needs further improvement. On the other hand, vanadium-based materials have demonstrated excellent performance for batteries and supercapacitors thanks to multiple oxidation states of vanadium (V 2+ , V 3+ , V 4+ , V 5+ ), while they have been suffering from unsatisfactory stability. ,− It is expected that the incorporation of vanadium into TiN might be a simple yet efficient way to optimize the overall performance with high capacitance and robust durability by utilizing the synergy between Ti and V.…”

Zinc-ion hybrid supercapacitors (ZIHCs) hold great promise in the realm of renewable energy storage. However, their development is severely hampered by the unsatisfactory practical capacity and poor stability. Herein, we report an effective strategy to improve the electrochemical performance by constructing hollow bimetallic nitride TiVN (H-TiVN) using a sacrificial template method. The optimized H-TiVN//Zn shows a high capacitance of 183.7 F g −1 at 0.2 A g −1 along with excellent stability (an 84.7% capacitance retention after 20,000 cycles at 5 A g −1 ). More importantly, the energy density can reach 57.42 Wh kg −1 , accompanied by a power density of 249.35 W kg −1 . Our work not only establishes H-TiVN as a high-performance electrode material for ZIHCs but also provides a general strategy for improving the electrochemical performance of nanomaterial electrodes.

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.

Zinc ion hybrid capacitors (ZIHCs), which integrate the features of the high power of supercapacitors and the high energy of zinc ion batteries, are promising competitors in future electrochemical energy storage applications. Carbon-based materials are deemed the competitive candidates for cathodes of ZIHC due to their cost-effectiveness, high electronic conductivity, chemical inertness, controllable surface states, and tunable pore architectures. In recent years, great research efforts have been devoted to further improving the energy density and cycling stability of ZIHCs. Reasonable modification and optimization of carbon-based materials offer a remedy for these challenges. In this review, the structural design, and electrochemical properties of carbon-based cathode materials with different dimensions, as well as the selection of compatible, robust current collectors and separators for ZIHCs are discussed. The challenges and prospects of ZIHCs are showcased to guide the innovative development of carbon-based cathode materials and the development of novel ZIHCs.
