Abstract Sodium‐ion batteries (SIBs) have a promising application prospect for energy storage systems due to the abundant resource. Amorphous carbon with high electronic conductivity and surface area is likely be most anode material SIBs. However, rate capability of amorphous in SIBs still big challenge because sluggish kinetics Na + ions. Herein, three‐dimensional (3DAC) controlled porous disordered structures synthesized via facile NaCl template‐assisted method. Combination open 3DAC,...
Abstract The safety hazards and low Coulombic efficiency originating from the growth of lithium dendrites decomposition electrolyte restrict practical application Li metal batteries (LMBs). Inspired by cost concentration electrolytes (LCEs) in industrial applications, dual‐salt LCEs employing 0.1 m difluorophosphate (LiDFP) 0.4 LiBOB/LiFSI/LiTFSI are proposed to construct a robust conductive interphase on anode. Compared with conventional using 1 LiPF 6 , ionic conductivity is reduced but...
We prepare a totally nonflammable phosphate-based electrolyte composed of 5 mol L-1 (M) Li bis(fluorosulfonyl) imide (LiFSI) in trimethyl phosphate (TMP) solvent. The concentrated M LiFSI/TMP shows good compatibility with graphite and no Al corrosion. More attractively, such can effectively suppress the growth dendrites metal batteries because stable LiF-rich SEI layer. Therefore, this highly is promising for safe batteries.
Abstract Considered the promising anode material for next‐generation high‐energy lithium‐ion batteries, SiO x has been slow to commercialize due its low initial Coulombic efficiency (ICE) and unstable solid electrolyte interface (SEI) layer, which leads reduced full‐cell energy density, short cycling lives, poor rate performance. Herein, a novel strategy is proposed in situ construct an artificial hybrid SEI layer consisting of LiF Li 3 Sb on prelithiated via spontaneous chemical reaction...
The notorious lithium (Li) dendrites and the low Coulombic efficiency (CE) of Li anode are two major obstacles to practical utilization metal batteries (LMBs). Introducing a dendrite-suppressing additive into nonaqueous electrolytes is one facile effective solutions promote commercialization LMBs. Herein, difluorophosphate (LiPO2F2, LiDFP) used as an electrolyte inhibit dendrite growth by forming vigorous stable solid interphase film on metallic anode. Moreover, CE can be largely improved...
Three-dimensional (3D) porous vanadium pentoxide (V2O5) thin films were synthesized by electrostatic spray deposition followed annealing at 350 °C in air. The interconnected pore networks facilitate the kinetics of lithium-ion diffusion and help V2O5 with stable capacity, high energy efficiency excellent rate capability as a cathode material for lithium batteries.
A well-designed nanostructure of transition metal oxides has been regarded as a key to solve their problems large volume changes during lithium insertion-desertion processes which are associated with pulverization the electrodes and rapid capacity decay. Here we report an effective approach for fabrication porous iron oxide ribbons by controlling nucleation growth precursor onto graphene surface followed annealing treatment. The resultant possess aspect ratio, structure, thin feature...
The applications of Na metal batteries (SMBs) are restricted owing to the capacity attenuation and safety hazards during cycling process, while a rational design electrolyte is critical on solving this problem. In work, an designed by adding 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether (TTE) into 3.8 M sodium bis(fluorosulfonyl)imide/1,2-dimethoxyethane (NaFSI/DME) electrolyte, forming localized high-concentration (LHCE) for constructing stable solid interface (SEI) SMBs.

Heteroatom-doped high-quality graphene is highly effective in encapsulating sulfur (S) and fabricating a high-performance electrode for lithium–sulfur (Li-S) batteries. Herein, simultaneously exfoliated boron-doped sheets (B-EEGs) are prepared via electrochemical exfoliation of graphite 1.0 mol L–1 Li bis(oxalato)borate (LiBOB)/dimethyl methylphosphonate (DMMP) electrolyte. The obtained B-EEG possesses high quality with large planar size ∼11 μm, few structure defects ID/IG = 0.26, low oxygen...
