“…The micromorphology of the composite electrodes can be optimized by adjusting the electrodeposition cycle. Xiong et al [ 103 ] prepared a new type of lignin-free carbonized wood hybrid as an effective scaffold for loading CoS/NiS nanofibers and Co/Ni flower-like structures of cobalt and nickel nanoparticles and as an electrode material for high-performance supercapacitors. The CoS/NiS nanofibers formed some new pore structures, which was helpful for the transport of electrolyte ions.…”

As a new type of energy storage device, supercapacitors have the advantages of high-power densities, high safety factors, and low maintenance costs, so they have attracted widespread attention among researchers. However, a major problem with supercapacitors is that their energy densities are not high enough, which limits their application. Therefore, it is crucial to expand the application scenarios of supercapacitors to increase their energy density as much as possible without diminishing their advantages. The classification and working principles of supercapacitors are introduced in this paper. The electrochemical properties of pure NiS materials, NiS composites with carbon materials, NiS composites with sulfide materials, and NiS composites with transition metal oxides for supercapacitors are summarized. This paper may assist in the design of new electrode materials for NiS-based supercapacitors.

[96] In a previous literature, Lv et al introduced an all-solid-state wood-inspired supercapacitor from RGO-coated wood transverse section slice (WTSS) (Figure 11f). Due to the hierarchical cellular architecture of wood substrate, the RGO@ WTSS electrode exhibited a 3D honeycomb porous skeleton that functioned as an electrolyte reservoir to sustain the mechanical flexibility, constant capacitive behavior (102 mF cm −2 ) and cycling reliability (98.9% capacity retention over 5000 cycles) under the bendable conditions.…”

It is a natural choice to realize the vision of wood‐inspired functional materials for energy engineering. Apart from being naturally abundant, renewable, and biodegradable, wood‐based devices possess hierarchically porous structures, mechanical integrity and flexibility, and tunable functionalities, holding the potential to significantly push the boundaries of efficient energy storage and conversion. Meanwhile, the hunting of batteries with superior energy/power output to redeem the ever‐growing energy demand has ignited a thick electrode conception, which is deemed as a burgeoning technic to maneuver the maximum active material loading at the device‐scale. As an integrated carbonaceous scaffold with hierarchical architecture and aligned channels, wood thick electrode ameliorates the ion/electron conductivities to strengthen the charge transfer kinetics. In this review, the rational design and unique prospects in the construction of wood thick electrodes that concerns over structural optimization and low‐tortuosity for integrated cell configuration are summarized. To trap the structure‐feature‐performance interplays, advanced wood thick electrode that opens an avenue in emerging energy chemistries such as supercapacitors, lithium‐ion/metal and post‐rechargeable batteries are also spotlighted with a standpoint on task‐tailored modification. Ultimately, the blueprint over ongoing challenges and upcoming opportunities for wood‐structured thick electrode is drawn to broaden their brand‐new energy talents.

“…The global energy shortage issues have stimulated growing demands for advanced electrochemical energy storage and conversion technologies. − Rechargeable metal–air batteries, especially zinc–air batteries benefitting from the exceptionally high energy density, cost-effective manufacturing, non-flammable, and non-explosive nature, demonstrate a very appealing candidate power source for next-generation electric vehicles, portable devices, and telecommunication applications. − However, the inadequate performances of zinc–air batteries largely stem from the polarization loss in the air cathode caused by the slow reaction rate of the electrochemical oxygen reduction reaction (ORR). , Typical commercial ORR catalysts are generally platinum-based materials, but their prohibitive cost, resource scarcity, and poor durability dramatically hampered the practicability and commercialization of zinc–air batteries. − Therefore, tremendous efforts have been dedicated to searching for alternative non-precious ORR catalysts from abundant natural resources. − …”

A strategy for one-dimensional nanofibrous Co@N-C oxygen reduction reaction (ORR) electrocatalysts was developed using nanofibrillated cellulose (NFC) as the scaffold material. In situ coupling of a Co-adenine (Co-Ad) complex on an NFC bio-template leads to populated and well spatial distribution of C, N, and Co active species after pyrolysis, which has a pivotal effect on facilitating ORR via a four-electron-dominated process. Additionally, the internal abundant micro- and mesopores in the carbon nanofiber skeleton ensure rapid mass transport and adequate exposure of active compositions. In combination with these advantages, the as-obtained Co-Ad/NFC-700 demonstrated superior ORR activity and endowed the fabricated Zn-air battery with superb performance: a high peak power density of 167 mW cm–2, an excellent specific capacity of 739 mA h g–1, and an excellent cyclability exceeding 40 h.
