Building a Flexible and Highly Ionic Conductive Solid Electrolyte Interphase on the Surface of Si@C Anodes by Binary Electrolyte Additives

“…As a result, silicon-based LIBs show low initial Coulombic efficiency and poor cycling performance, thus limiting its practical applications. 13,14 In response to the structural instability of Si anodes during cycling, many strategies have been proposed, such as nanoengineered Si to prevent particle cracking and crushing, 15,16 construction of core−shell or yolk−shell nanostructures to accommodate volume expansion, 17,18 structure optimization of active materials, and new functional binders and electrolyte engineering. 19,20 Among these strategies, the technique of electrolyte additive is considered to be a promising technique due to its simplicity.…”

“…Structural optimization involves designing the battery structure to minimize the amount of inactive components and maximize the amount of active materials. , Electrode modification includes surface coating and composite fabrication, which can enhance the electrochemical properties of the electrodes. − Among them, silicon (Si) has attracted great attention as a promising anode material in LIBs mainly due to its low discharge potential (<0.5 V) and large theoretical storage capacity (4200 mAh g –1 ). , However, the Si anode undergoes severe volume expansion (>300%) during the lithiation/delithiation process, which results in the crushing of Si particles and the rupture of the solid electrolyte interphase (SEI). As a result, silicon-based LIBs show low initial Coulombic efficiency and poor cycling performance, thus limiting its practical applications. , In response to the structural instability of Si anodes during cycling, many strategies have been proposed, such as nanoengineered Si to prevent particle cracking and crushing, , construction of core–shell or yolk–shell nanostructures to accommodate volume expansion, , composition and structure optimization of active materials, and new functional binders and electrolyte engineering. , Among these strategies, the technique of electrolyte additive is considered to be a promising technique due to its simplicity.…”
