An ionic liquid (IL) incorporated in a quasi-solid-state electrolyte (ILQSE) is prepared using 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF4) and poly (ethylene glycol dimethacrylayte) (PEGDMA) for high-temperature application of supercapacitors. The ILQSE displays thermal stability up to 150 °C the supercapacitors exhibit specific capacitance 134 F g-1.
Harsh oxidation of 1 nm single-walled carbon nanotubes (SWCNTs) can lead to fatal defect structures, which jeopardize their mechanical and electrical performances. Here, we show the structural recovery highly oxidized SWCNTs (Ox-SWCNTs), were rapidly (within h) by kneading without forming failure-causing defects inspired flour dough. The rational debundled led obtaining thermodynamically stable SWCNT solutions in water or even alcohol dispersant molecules. Importantly, structure Ox-SWCNTs...
We developed a flexible supercapacitor cell with biocompatible oxidized SWCNTs driven by electrolytes in body fluids through integration wireless sensor network for use implantable electronic medical devices (IEMDs).
Abstract Innovative anode materials are essential for achieving high‐energy‐density lithium‐ion batteries (LIBs) with longer lifetimes. Thus far, only a few studies have explored the use of layered perovskite structures as LIB materials. In this study, study demonstrates performance and charge/discharge mechanism previously undefined Ruddlesden‐Popper Li₂La₂Ti₃O₁₀ (RPLLTO) an material LIBs. RPLLTO exhibits two unique voltage plateaus ≈0.6 0.4 V(vs Li/Li + ), due to insertion lithium ions...
The increasing demand for efficient energy storage has led to increased research on sodium-ion batteries (SIBs) as a promising alternative lithium-ion batteries. However, the anode materials currently employed in are not suitable SIBs, highlighting need development of appropriate materials. In this study, cellulose- and lignin-rich residues extracted from wood biomass were converted hard carbon, their performance SIBs was evaluated. Cellulose lignin separated larch using deep eutectic...
Abstract The phase control of spinel LiNi 0.5 Mn 1.5 O 4 was achieved through surface treatment that led to an enhancement its electrochemical properties. Li + diffusion inside could be promoted by modifying the structure phosphidation into a disordered ( Fd 3 m ) allows facile transport. Phosphidated showed significantly enhanced performance, even at high rates exceeding 10 C, demonstrating improved kinetics (related amount 3+ can render competitive as high‐power cathode material for...
Carbon materials have gained considerable attention in recent years due to their superior properties. Activated carbon has been used supercapacitors its density and rapid adsorption capability. The sp2–sp3 hybrid porous are synthesized using herringbone-type nanofibers (CNFs) carbonized spherical phenol resins, with KOH as the activating agent. morphology of facilitates formation ribbon-like nanosheets from highly activated CNFs wrapped around resin-based carbon. etching separation produce a...
Abstract We report the optimized electrochemical performance of a hybrid supercapacitor constructed with cokes‐derived activated carbon (CAC) and Li 4 Ti 5 O 12 /carbon nanotube (LTO/CNT), which has improved capacitance rate capability. The CAC is attributed to additional shallow intercalation due remaining graphitic structure ion adsorption via surface area pore structure. partially maintained adjusted KOH activation conditions. capability LTO/CNT affected by increase in electronic...
Recently, lithium-ion batteries have been increasingly used as energy sources for electric vehicles, and research has highlighted the need to improve stability of these batteries. In this study, we propose a novel inorganic coating method that utilizes sub-micron boehmite particles agents enhance thermal mechanical battery separator.
