The abundance of alkaline sodium (Na) is promising toward achieving a better, cheaper and more efficient energy storage system for renewable energy integration into the electric grid. However, the intercalation-based anode materials of Na-ion battery are inadequate in storing bulky Na ions which raises the concern about efficient reversibility. Desirable alternatives are alloy-based anode material such as tin (Sn), which has relatively high theoretical capacity of 847 mAh/g (for complete conversion of Na₁₅Sn₄). However, rapid volume expansion, which strains basic Sn skeletons, coupled with more frequent and extreme noxious events linked to electrolyte decomposition exacerbates the Na-Sn cycling properties and deteriorate the reversibility. The goal of this study to is to wade through different combinations of binders and electrolytes and extract kinetic and transport properties of Sn based Na-ion chemistry and to elucidate mechano-electrochemical underpinnings thereof.
