Abstract The Co-based organic skeleton was combined with graphene oxide (GO) as a precursor, Ni 2+ hydrolysis etching introduced, and finally, NiCo-LDH obtained. final composite electrode material NiCo 2 S 4 /rGO obtained by high-temperature vulcanization. introduction of MOFs rGO significantly increased the specific surface area made it have excellent electrochemical properties. capacitance /20rGO reaches an astonishing 2452.65 F g − 1 when current density is A . In addition, at large 10 , can also reach 1250 after long cycle 5000 cycles such density, capacity remains original 73.2%. With positive activated carbon negative electrode, hybrid supercapacitor assembled. At energy 56.9 Wh kg its power 799 W still has retention rate 74% properties composites demonstrated in this work open up new possibilities for high-quality storage devices.

Abstract Ternary metal sulfides (TMSs) have garnered significant attention as alternative electrode materials for rechargeable metal‐ion battery anodes and electrodes electrochemical supercapacitors (SCs). With the escalating costs of lithium, research has shifted toward sources like sodium‐ion batteries (NIBs) potassium‐ion (KIBs), offering cost‐effectiveness greater natural abundance globally. However, pursuing suitable beyond lithium‐ion (LIBs), such NIBs, KIBs, SCs with enhanced energy power density, remains a formidable challenge. In this context, TMSs demonstrate remarkable reversibility NIB, KIB, SC materials, showcasing multi‐electron redox reactions, improved electronic conductivity, higher theoretical capacities. Numerous articles highlighted promising future conversion storage (EECS). Nonetheless, practical applications are hindered by limitations, including structural stability during long‐standing cyclability, scalability. This review systematically demonstrates how varying synthesis routes can tailor nanostructures their influence on activity. Additionally, an in‐depth literature survey is provided performances in summarize recent advancements best available literature. Moreover, prospects challenges highlighted, expressing optimism that will emerge pivotal EECS.

Abstract Herein, the performance of asymmetric supercapacitors (ASC) fabricated using ZnCo 2 O 4 (ZCO) nano‐hexagons and orange peel‐derived activated carbon (OPAC) as electrodes was studied. ZCO prepared by a double hydroxide method OPAC from peel followed KOH activation. For ZCO, calcination temperature determined TGA analysis. The XRD showed presence cubic spinel structure. chemical structure analyzed XPS, FTIR, Raman spectroscopy respectively. OPAC, an amorphous nature inferred; FTIR studies indicate functional groups defect in material. observed SEM TEM interconnected pore image. specific capacitance for found to be 194 F.g −1 159 at current density 0.25 A.g . Further, ASC positive negative electrode 2M KOH‐soaked separator. A cell voltage 1.2 V achieved calculated 64 cyclic stability changes electrode/electrolyte interface were
