Nitrogen-doped carbon nanofiber webs (CNFWs) with high surface areas are successfully prepared by carbonization-activation of polypyrrole KOH. The as-obtained CNFWs exhibit a superhigh reversible capacity 943 mAh g−1 at current density 2 A even after 600 cycles, which is ascribed to the novel porous nanostructure and high-level nitrogen doping.
The olivine LiFePO4 now stands as a competitive candidate of cathode material for the next generation green and sustainable lithium-ion battery system due to its long life span, abundant resources, low toxicity, high thermal stability. In this review, we focus on discuss structure, synthesis, electrochemical behavior, mechanism, problems encountered in application. major goal is highlight some recent development with rate capability, energy density, excellent cyclability resulting from...
We report on the energetics of intercalation lithium, sodium and potassium in graphite by density functional theory using recently developed van der Waals (vdW) functionals. First stage compounds are well described conventional functionals like GGA, but crucial for higher graphite, where interactions important. The vdW-optPBE gave best agreement with reported structure LiC6 was further applied Na K. enthalpy formation KC8 were found to be −16.4 −27.5 kJ mol−1 respectively. NaC6 NaC8 unstable...
Abstract Poor cycling stability and safety concerns regarding lithium (Li) metal anodes are two major issues preventing the commercialization of high‐energy density Li metal‐based batteries. Herein, a novel tri‐layer separator design that significantly enhances batteries is presented. A thin, thermally stable, flexible, hydrophilic cellulose nanofiber layer, produced using straightforward paper‐making process, directly laminated on each side plasma‐treated polyethylene (PE) separator. The...

Abstract Membrane with ordered channels is the key to controlling ion sieving and proton conductivity in flow batteries. However, it remains a great challenge for finely nanochannels of polymeric membranes. Herein, two types acid‐stable Zr‐metal organic framework (MOF‐801 MOF‐808) variable pore structures channel properties are introduced as fillers into non‐fluorinated sulfonated poly (ether ether ketone) (SPEEK). The membrane incorporated MOF‐801 smaller triangular window (≈3.5 Å)...
Although aqueous zinc-ion batteries (AZIBs) promise high capacity, low cost, and environmental friendliness, the Zn metal anode suffers from limited reversibility unsatisfied lifespan arising severe dendritic growth inevitable interfacial corrosion. In this regard, constructing artificial protective layer on foil has been recognized as an effective strategy to realize durable AZIBs. Inspired by phytic acid (PA) anticorrosion conversion coating for industrial protection, herein, we designed a...
Abstract Waste tyres (WTs) are a major global issue that needs immediate attention to ensure sustainable environment. They often dumped in landfills or incinerated open environments, which leads environmental pollution. However, various thermochemical conversion methods have shown promising results as treatment routes tackle the WT problem while creating new materials for industries. One such material is char, has properties comparable those of carbon used an active electrode batteries....
Abstract Rechargeable aqueous zinc batteries (RAZBs) suffer from the structural degradation of layered oxide cathode, parasitic side reaction on Zn foil as well often‐overlooked self‐discharge phenomenon at elevated temperatures. Herein, this study presents a thin‐layer (9 µm) molecular‐engineered separator strategy to achieve concurrent shelf life, cycling endurance, practical energy density for RAZBs prototype. On face‐to‐cathode side, biphthalic anhydride is anchored onto polyethylene...
The poor stability of LiPF6-based electrolytes has always been a bottleneck for conventional lithium-ion batteries. presence inevitable trace amounts moisture and the operation batteries at elevated temperatures are particularly detrimental to electrolyte stability. Here, lithium 2-trifluoromethyl-4,5-dicyanoimidazole (LiTDI) is investigated as moisture-scavenging additive can sufficiently suppress hydrolysis LiPF6. With 2 wt % LiTDI, no LiPF6 degradation be detected after storage 35 days,...
