Massive efforts have been devoted to enhancing performances of Li–S batteries meet the requirements practical applications. However, problems remain in energy density and improving cycle life. We present a free-standing structure walnut-shaped VS4 nanosites combine with carbon nanotubes (NTs) as cathodes. In this framework, NT arrays provide high surface area conductivity for sulfur loadings, facilitate trapping catalytic conversions lithium polysulfides. The synergistic effects enabled rate...
Abstract Polyethylene oxide (PEO)‐based solid polymer electrolytes exhibit promising commercial prospects due to their superior processability and scalability. However, limited ion transport unstable electrode/electrolyte interface restrict practical application. Herein, the paraelectric strontium titanate (STO) is introduced into PEO‐based solve those problems. The electrostatic force originating from polarized STO weakens coordination between EO Li + releases more free , thus promoting...
Nanoporous composite films of multi-walled carbon nanotubes (MWNTs) and polyaniline (PAn) were grown electrochemically from acidic aqueous solutions, such that the constituents deposited simultaneously onto graphite electrodes. Scanning electron microscopy (SEM) revealed consisted nanoporous networks MWNTs coated with PAn. Cyclic voltammetry (CV) electrochemical impedance spectroscopy (EIS) demonstrated these had similar response rates to pure PAn films, but a lower resistance much improved...
Abstract Room‐temperature sodium‐ion batteries have attracted great attentions for large‐scale energy storage applications in renewable energy. However, exploring suitable anode materials with high reversible capacity and cyclic stability is still a challenge. The VS 4 , parallel quasi‐1D chains structure of V 4+ (S 2 2− ) which provides large interchain distance 5.83 Å capacity, has showed potential sodium storage. Here, the uniform cuboid‐shaped nanoparticles are prepared as by...

Garnet-type Li7La3Zr2O12 (LLZO) is one of the most promising solid-state electrolytes (SSEs). However, application LLZO limited by structural instability, low ionic conductivity, and poor lithium stability. To obtain a garnet-type solid electrolyte with stable structure high series TaCe co-doping cubic Li6·4La3Zr1.4-xTa0.6CexO12 (LLZTCO, x = 0, 0.02, 0.04, 0.06, 0.08, 0.10, 0.20, 0.30) were successfully synthesized through conventional solid-phase method. The Ta5+ doping can introduce more...
Abstract The limited ionic conductivity at room temperature and the constrained electrochemical window of poly(ethylene oxide) (PEO) pose significant obstacles that hinder its broader utilization in high‐energy‐density lithium metal batteries. garnet‐type material Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) is recognized as a highly promising active filler for enhancing performance PEO‐based solid polymer electrolytes (SPEs). However, still by high interfacial resistance. In this study, novel...
