Abstract Phosphorus doped carbons are of particular interest as anode materials because their large interlayer spacing and strong adsorption Na + ions. However, it remains challenging to achieve high phosphorus doping due the limited choices sources difficulty in constructing oxygen‐free synthesis system. Herein, a new strategy is proposed prepare ultrahigh phosphorus‐doped carbon (UPC) anodes for performance sodium ion batteries (SIBs). By using two commonly available, miscible, evaporable...
Prussian blue analogues (PBAs) are considered one of the promising cathodes for sodium-ion batteries because their low cost and tunable structure. As an intrinsic characteristic, influence structured water in PBAs on electrochemical properties is still controversial. Herein, low-vacancy iron hexacyanoferrate with different interstitial contents synthesized through citric acid-assisted single source method. Ex situ Fourier transform infrared X-ray diffraction characterization reveals that can...
Lithium metal anodes have long been considered as "holy grail" in the field of energy storage batteries, but dendrite growth and large volume changes hinder their practical applications. Herein, a facile eco-friendly CF4 plasma treatment is employed for surface modification Li anodes, an artificial layer consisting LiF Li2 C2 fabricated first time. Experimental results theoretical calculations reveal that high adsorption low Li+ diffusion barriers induce uniform nucleation planar Li,...
Engineering F-rich solid electrolyte interphase (SEI) layers is regarded as an effective strategy to enable the long-term cycling stability of potassium-ion batteries (KIBs). However, in conventional KPF
A covalent sulfur–carbon (covalent-SC) composite is successfully prepared in situ by a wet-chemical solvothermal method based on the strong interaction between carbon disulfide (CS2) and red phosphorus. It demonstrated that sulfur uniformly distributes among boundary interior of skeleton with formation S–C bonds. Moreover, can be electrochemically activated under 0.5 V then functions as capacity sponsor, because Na+ freely transfer into interlayer (with stable enlarged distance ∼0.4 nm after...
Abstract Constructing a flexible and chemically stable multifunctional layer for the lithium (Li) metal anodes is highly effective approach to improve uneven deposition of Li + suppress dendrite growth. Herein, an organic protecting polythiophene in situ polymerized on via plasma polymerization. Compared with thiophene (C‐PTh), (P‐PTh), higher Young's modulus 8.1 GPa, shows strong structural stability due chemical binding Li. Moreover, nucleophilic C─S bond facilitates decomposition salts...
Enhanced phosphorus (7.2 wt%) and sulfur (15.7 co-doped carbon (PSC) is synthesized <italic>via</italic> a one-step sintering of disulfide red in vacuum.
A simple and effective plasma functionalization technique for grafting fluorine-containing functional groups on commercial PP separators to induce the formation of LiF-rich SEI films has been proposed.
Abstract Organic carboxylates are well‐accepted as low‐cost anodes for sodium‐ion batteries, owing to their abundant natural resources, structural versatility and suitable potentials. In this work, sodium benzene‐1,2,4‐tricarboxylate (Na‐1,2,4‐BTC), featured an asymmetric carboxylic‐based coordination salt, is studied a Na storage anode. The ions exhibit diffusion‐controlled behavior involving the enolization of C=O groups in Na‐1,2,4‐BTC. Meanwhile, benefiting from its robust organic‐metal...
Wireless Mesh Network is a type of wireless networks in which demands bandwidth for users has mobility. The backbone node placement mesh dynamic scenario investigated, and the TSDPSO algorithm used to adapt environment, updates deployment location changes demand if it detects environmental at beginning cycle time. In order meet network connectivity, particle swarm optimization employed select gateway location, then nodes added constantly until all requirement covered. experimental results...
