“…However, the research on SICs and PICs started late, and the radii of Na + and K + are larger than Li + , resulting in a slower ion diffusion rate and poor kinetics in the anodes. 14 Therefore, to further match the dynamics between the anode and cathode, NBMO still needs to 73 The ultrathin carbon shell effectively ensured the stability of the defect lattice, limited the reaction of MnNb 2 O 6 with the electrolyte, and replaced the solid-state ion-exchange membrane.

To reduce the kinetic imbalance between the anode and cathode electrodes of metal-ion capacitors (MICs), researchers have conducted intensive explorations to develop new anode materials. Niobium-based oxides (NBOs) have been established as typical anodes for MICs. Unfortunately, conventional NBOs can hardly meet the future demands for high-power applications. The niobium-based mixed oxides (NBMOs) formed by doping niobium oxides with other elements (Ti, P, V, Cr, etc.) are drawing immense interest for advanced MICs as competitive anodes. Unlike the conventional layered Nb2O5, NBMOs exhibit diverse structures (Wadsley–Roth phase, tungsten bronze structure, ABO3 perovskite structure, etc.), which renders them appealing merits including enhanced specific capacities, higher electronic/ionic conductivities, etc., for MICs. Even so, there is still extensive room for progress to further improve their electrochemical kinetics. In this Review, we systematically summarize the doping species, crystal structures, charge-storage mechanism, synthesis strategies, and recent contributions/progress of diverse NBMOs for advanced MICs toward advancing the process of practical applications. Besides, the challenges and prospects in the booming field are proposed. The review will guide future purposeful design and controllable synthesis of high-performance anodes for next-generation MICs.

“…Instead, hybrid supercapacitors (HSCs), which are composed of battery-type electrodes with rich redox reactions and capacitor-type electrodes with fast ionic conductivity, may provide a good solution, because HSCs would combine the benefits of batteries and capacitors to meet the requirements of energy storage systems that require both a high energy density and a high power density. [17][18][19][20][21] The HSCs are classified as alkali metal ion (Li + /Na + / K + ) HSCs [22][23][24][25] or multivalent metal ion (Zn 2+ /Mg 2+ /Ca 2+ / Al 3+ ) [26][27][28] HSCs, based on the different metal ion types. In recent years, extensive investigations on these HSCs have been performed and most were related to lithium-ion HSCs, although a number of issues still existed for lithiumion HSCs in practice.…”

Zinc‐ion hybrid supercapacitors (ZHSCs) may be the most promising energy storage device alternatives for portable and large‐scale electronic devices in the future, as they combine the benefits of both supercapacitors and zinc‐ion batteries. Even though many surprise outcomes have been accomplished with ZHSCs, the creation of suitable cathode materials and electrolytes, as well as the enhancement of zinc anodes, continue to be the most difficult obstacles in the development of high‐performance ZHSCs. The low capacitance of the cathode material, poor stability, and low utilization rate of the zinc anode seriously affect the electrochemical performance and application of ZHSCs. Furthermore, parasitic processes in aqueous electrolytes, such as the hydrogen and oxygen evolution reactions might result in low‐voltage windows and unsatisfied cycling performance of the ZHSCs. This review provides a concise summary of the most recent developments and energy storage mechanisms in ZHSCs. Meanwhile, the cathode material design strategy (structural engineering, hybrid‐composite design, heteroatom doping, and so on), the zinc anode design strategy (zinc foil improvement, zinc‐free metal composites, and so on), and the structure–activity relationship of the electrochemical performance of ZHSCs are discussed. Additionally, a summary of the impact of modifications in electrolyte composition on the electrochemical performance of ZHSCs is provided. Finally, this review also discusses the future development direction of ZHSCs. It is anticipated that this evaluation will serve as a helpful reference for the creation of high‐performance ZHSCs, which will hasten the development of these devices.

Hybrid ion capacitors (HICs) have aroused extreme interest due to their combined characteristics of energy and power densities. The performance of HICs lies hidden in the electrode materials used for the construction of battery and supercapacitor components. The hunt is always on to locate the best material in terms of cost‐effectiveness and overall optimized performance characteristics. Functionalized biomass‐derived porous carbons (FBPCs) possess exquisite features including easy synthesis, wide availability, high surface area, large pore volume, tunable pore size, surface functional groups, a wide range of morphologies, and high thermal and chemical stability. FBPCs have found immense use as cathode, anode and dual electrode materials for HICs in the recent literature. The current review is designed around two main concepts which include the synthesis and properties of FBPCs followed by their utilization in various types of HICs. Among monovalent HICs, lithium, sodium, and potassium, are given comprehensive attention, whereas zinc is the only multivalent HIC that is focused upon due to corresponding literature availability. Special attention is also provided to the critical factors that govern the performance of HICs. The review concludes by providing feasible directions for future research in various aspects of FBPCs and their utilization in HICs.
