“…In recent times, research on the advancement of sustainable and eco-friendly energy storage/conversion technologies has attracted considerable attention from the scientific community to surmount the rising energy demands worldwide. − Among the different preeminent energy storage cells, supercapacitors (SCs) have gained extensive interest owing to their intrinsic safety, rapid charging/discharging, high power density, durability, and high efficiency. − However, the relatively lower specific energy of SCs compared to that of conventional secondary batteries has restricted their commercial application. − Assembling asymmetric SCs (ASCs) using battery-like Faradaic positive materials and nanoporous carbon-related negative materials with superior capacity and a large working voltage window could produce an exalted energy density. Apart from energy storage, the production of high-purity and renewable hydrogen fuel using electrochemical water-splitting (EWS) technology (energy conversion device) is considered an indispensable future energy resource. ,− The EWS process includes two core half-cell reactions: hydrogen and oxygen evolution reactions (HER and OER, respectively) at the cathode and anode sides, respectively. , The OER process is more crucial and requires a higher overpotential than the HER because of its four-electron-transfer process associated with sluggish reaction kinetics.…”

The anionic components have a significant role in regulating the electrochemical properties of mixed transition-metal (MTM)-based materials. However, the relationship between the anionic components and their inherent electrochemical properties in MTM-based materials is still unclear. Herein, we report the anion-dependent supercapacitive and oxygen evolution reaction (OER) properties of in situ grown binary Ni–Co–selenide (Se)/sulfide (S)/phosphide (P) nanosheet arrays (NAs) over nickel foam starting from MOF-derived Ni–Co layered double hydroxide precursors. Among them, the Ni–Co–Se NAs exhibited the best specific capacity (289.6 mA h g–1 at 4 mA cm–2). Furthermore, a hybrid device constructed with Ni–Co–Se NAs delivered an excellent energy density (74 W h kg–1 at 525 W kg–1) and an ultra-high power density (10 832 W kg–1 at 46 W h kg–1) with outstanding durability (∼94%) for 10 000 cycles. Meanwhile, the Ni–Co–Se NAs showed superior electrocatalytic OER outputs with the lowest overpotential (235 mV at 10 mA cm–2) and Tafel slope. In addition, Ni–Co–Se NAs outperformed IrO2 as an anode in an anion exchange membrane water electrolyzer at a high current density (>1.0 A cm–2) and exhibited a stable performance up to 48 h with a 99% Faraday efficiency. Theoretical analyses validate that the Se promotes OH adsorption and improves the electrochemical activity of the Ni–Co–Se through a strong electronic redistribution/hybridization with an active metal center due to its valence 4p and inner 3d orbital participations. This study will provide in-depth knowledge of bifunctional activities in MTM-based materials with different anionic substitutions.

“…This surge in interest is a response to the growing global demand for renewable energy sources. Among the various energy storage solutions, supercapacitors (SCs) have emerged as a prominent area of investigation. − This heightened attention is attributed to their inherent safety features, swift charge–discharge capabilities, elevated power density, robustness, and overall efficiency. Despite these advantages, SCs face limitations, primarily in energy density compared with traditional secondary batteries.…”

Achieving a high energy density and long-cycle stability in energy storage devices demands competent electrochemical performance, often contingent on the innovative structural design of materials under investigation. This study explores the potential of transition metal selenide (TMSe), known for its remarkable activity, electronic conductivity, and stability in energy storage and conversion applications. The innovation lies in constructing hollow structures of binary metal selenide (CoNi-Se) at the surface of reduced graphene oxide (rGO) arranged in a three-dimensional (3D) morphology (CoNi-Se/rGO). The 3D interconnected rGO architecture works as a microcurrent collector, while porous CoNi-Se sheets originate the active redox centers. Electrochemical analysis of CoNi-Se/rGO based-electrode reveals a distinct faradic behavior, thereby resulting in a specific capacitance of 2957 F g −1 (1478.5 C g −1 ), surpassing the bare CoNi-Se with a value of 2149 F g −1 (1074.5 C g −1 ) at a current density of 1 A g −1 . Both materials exhibit exceptional high-rate capabilities, retaining 83% of capacitance at 10 A g −1 compared to 1 A g −1 . In a two-electrode coin cell system, the device achieves a high energy density of 73 Wh kg −1 at a power density of 1500 W kg −1 , stating an impressive 90.4% capacitance retention even after enduring 20,000 cycles. This study underscores the CoNi-Se/rGO composite's promise as a superior electrode material for high-performance energy storage applications.

“…[ 10 ] However, the difference between electrons and lattice at the heterogeneous interface of unsuitable heterostructures can also reduce ion and electron transfer kinetics. [ 11 ] Therefore, enhancement in the electron and ion transfer kinetics of NiCo phosphide (NCP) by selecting appropriate composite materials and designing suitable heterostructures is highly desirable for advanced applications.…”

Nickel‐cobalt (NiCo) phosphides (NCPs) possess high electrochemical activity, which makes them promising candidates for electrode materials in aqueous energy storage devices, such as supercapacitors and zinc batteries. However, the actual specific capacitance and rate capability of NCPs require further improvement, which can be achieved through reasonable heterostructural design and loading conditions of active materials on substrates. Herein, novel hierarchical Bi‐NCP heterogeneous structures with built‐in electric fields consisting of bismuth (Bi) interlayers (electrodeposited on carbon cloth (CC)) were designed and fabricated to ensure the formation of uniform high‐load layered active materials for efficient charge and ion transport. The resulting CC/Bi‐NCP electrodes showed a uniform, continuous, and high mass loading (>3.5 mg) with a superior capacitance reaching 1200 F⋅g−1 at 1 A⋅g−1 and 4129 mF⋅cm−2 at 1 mA⋅cm−2 combined with high‐rate capability and durable cyclic stability. Moreover, assembled hybrid supercapacitors, supercapatteries, and alkaline zinc batteries constructed using these electrodes delivered high energy densities of 64.4, 81.8, and 319.1 Wh·kg−1, respectively. Overall, the constructed NCPs with excellent aqueous energy storage performance are potential for the development of novel transition metal‐based heterostructure electrodes for advanced energy devices.This article is protected by copyright.
