We report the electrochemical study of cubic and monoclinic NiP2 polymorphs toward Li, as a candidate for anodic applications Li-ion batteries. found that form is most attractive one performance-wise. Monoclinic can reversibly uptake 5 lithium per formula unit, leading to reversible capacities 1000 mAh/g at an average potential 0.9 V vs Li+/Li°. From complementary X-ray diffraction (XRD) HRTEM (high-resolution transmission electron microscopy) measurements, it was shown that, during first...
FePy (y = 1, 2, 4) anodes all react with lithium through a conversion reaction + 3yLi → yLi3P Fe0 in their first discharge, leading to nanocomposite discharged electrodes described by nanosized particles embedded matrixes. From electrochemical and complementary situ X-ray diffraction high-resolution transmission electron microscopy studies, we deduce that the occurring during discharge is followed two successive insertion processes further cycles for FeP electrode. The process highly...
High-performance flexible pressure sensors have an essential application in many fields such as human detection and human-computer interaction. Herein, on the basis of dielectric layer a bionic komochi konbu structure, we propose low-cost novel capacitive sensor that achieves high sensitivity stability over broad range tactile pressures. Further, durable electrode transparent junctionless copper/nickel-nanonetwork was prepared based electrospinning electroless deposition techniques, which...
Nickel nitride has been prepared through different routes involving ammonolysis of precursors (Ni(NH3)6Br2 or nickel nanoparticles obtained from the reduction nitrate with hydrazine) and thermal decomposition amide by precipitation in liquid ammonia. The electrochemical behavior against lithium was tested all cases, specific capacity being much larger for latter (1200 mA h g−1 compared to 85 125 respectively). Ni3N 'cast' electrodes exhibited good rate capability, 500 reversible maintained...
We present an efficient method for computing acoustic energy within complex-shaped geometries and cavities with obstacles in the mid-high frequency range. This is based on Simplified Energy Method (MES), known its accuracy such ranges but traditionally limited to simple cavity shapes. The proposed hybrid integrates techniques of ray triangle intersection MES formulation address these limitations. By calculating points rays, we identify obstructing elements before transfer between boundary...
Zn3P2 zinc phosphide was synthesized as powders by three different preparation routes: ball-milling, ball-milling followed annealing, and ceramics at high temperature. Depending on the synthetic route, various powder morphologies (size crystallinities) were obtained. The electrochemical reactivity toward lithium of these is shown to be unique despite some quantitative performance differences. insertion mechanism involve two distinct but parallel reversible pathways for a large number...
The study presents a combined experimental and computational of Li+ extraction/insertion mechanisms in cubic-fcc transition metal pnictides LixMPn4 (MPn = TiP, VP, VAs). Exhibiting high specific capacities (Cmax 830 mA h g-1) at potential close to 1 V, these materials have been recently proposed as promising negative electrode for Li-ion battery. In situ XRD first-principle electronic structure calculations including full structural relaxations are used correlate the reversible phase...
We present the ternary phases LixVPn4 (Pn = P, As) as new materials for negative electrode in lithium-ion batteries. Associated with a large variation of lithium content per formula unit (3 ≤ x 7.5 P and 3 11 As), these show higher specific capacities their first charge/discharge cycle than graphite (550 mA·h/g Pn 530 As vs 372 m·Ah/g Cgr) open routes design types rechargeable Li-ion High-temperature syntheses, X-ray diffraction analyses, first-principle electronic structure calculations...
The present work provides a comparative study of the electrochemical behaviors binary and ternary manganese phosphides toward lithium. redox mechanism involved in these two electrodes is elucidated by means galvanostatic situ X-ray diffraction measurements first-principles calculations. Compared to previous reported on MnP4, additional processes are here clearly identified: after first conversion process that transforms MnP4 electrode into Li7MnP4, partial irreversible decomposition Li7MnP4...
