Significant electrochemical performance improvement of TiSnSb as anode material for Li-ion batteries with composite electrode formulation and the use of VC and FEC electrolyte additives

Amorphous-silicon@silicon oxide/chromium/carbon as an anode for lithium-ion batteries with excellent cyclic stability

“…The electrolyte was 1 M LiPF 6 with 5 wt% fluorinated ethylene carbonate (FEC) and 2 wt% vinylene carbonate (VC) as the electrolyte additives, which were dissolved in ethylene carbonate, dimethyl carbonate and ethyl methyl carbonate with a volume ratio of 1:1:1. Herein, the use of FEC and VC as additives is to form a compact and stable solid-liquid interface (SEI) film on the surface of the electrode materials [30,31]. The charge-discharge measurements of the cells were performed at different current densities over a potential window of 0.0-1.5 V using Neware instruments.…”

The Solid Electrolyte Interphase a key parameter of the high performance of Sb in sodium-ion batteries: Comparative X-ray Photoelectron Spectroscopy study of Sb/Na-ion and Sb/Li-ion batteries

“…It has been reported that the good electrochemical performance of metalloïds (Sb, P…) based negative electrode material in Li-ion batteries are correlated with the formulation with the carboxymethyl cellulose binder [29,30].…”

At the Heart of a Conversion Reaction: An Operando X-ray Absorption Spectroscopy Investigation of NiSb2, a Negative Electrode Material for Li-Ion Batteries

“…5 TiSnSb is another interesting case for which electrode formulation together with a tailored electrolyte composition produced a spectacular improvement of the performances, with a stable capacity maintained over several hundred cycles. 8 MSb x compounds are expected to react with lithium by forming a matrix of Li 3 solution. Secondly, the back-conversion reaction was found to be incomplete, with the formation of some Sb metal, and of an ill-defined Sb-depleted NiSb 2 polymorph, which was supposed to crystallise with the structure of a high pressure NiSb 2 phase.…”
