Abstract In this work, a novel high entropy hydroxide NiCoMoMnZn‐layered double hydroxide(LDH) is synthesized as an electrode material for supercapacitors using template re‐etching method to promote the energy density. As positive supercapacitors, NiCoMoMnZn‐LDH has advantage of uniform distribution elements, specific surface area, porous and stable structure. More importantly, capacitance can reach 1810.2 F g −1 at current density 0.5 A , NiCoMoMnZn‐LDH//AC HSC assembled from up 62.1 Wh kg power 475 W . Moreover, influence different compositions on their morphological, structural, electrochemical properties investigated based characterization results. Then, synergistic mechanism among components revealed in detail by DFT calculations. addition, synthesis strategy proposed work high‐entropy hydroxides exhibits universality. Experimental results show that successfully avoids not only phase separation element aggregation formation materials, but also reduces structural distortion, which beneficial efficient large‐scale hydroxides.

Nanostructured binary transition-metal-sulfides and nanocomposites as high-performance electrodes for hybrid supercapacitors

Applied Physics Reviews, Год журнала: 2024, Номер 11(2)

Опубликована: Май 13, 2024

Supercapacitors (SCs) are attractive as promising energy storage devices because of their distinctive attributes, such high power density, good current charge/discharge ability, excellent cyclic stability, reasonable safety, and low cost. Electrode materials play key roles in achieving performance these SCs. Among them, binary transition metal sulfides (BTMSs) have received significant attention, attributed to conductivity, abundant active sites, electrochemical properties. This topic review aims summarize recent advances principles, design, evaluation the for nanostructured BTMSs (including nickel–cobalt sulfides, zinc–cobalt copper–cobalt sulfides.) nanocomposites those carbon nanomaterials, oxides, polymers). Nanostructuring well effects on were discussed, including nanoparticles, nanospheres, nanosheets, nanowires, nanorods, nanotubes, nanoarrays, hierarchitectured nanostructures. Their has further been reviewed specific capacitance, rate capability, cycling stability. In addition, hybrid supercapacitors (HSCs) assembled using cathodes also summarized compared. Finally, challenges prospects HSCs-based BTMS electrodes presented.
