Sodium-ion batteries hold great promise for large-scale energy storage but face significant challenges at extreme temperatures. Especially high temperatures, side reactions and electrode dissolution are exacerbated by repeated cycling. It is, therefore, essential to optimize the electrolyte formulation. Here, a series of siloxane molecules screened boost high-temperature performance anode materials in SIBs. Octamethyltrisiloxane (MDM), as result this screening, prefers interact with anions due unique electron-donating Si→CH3. This association then weakens P─F bond facilitates formation NaF-rich solid interphase. Additionally, MDM inhibits hydrolysis PF6 -, reducing deleterious species electrolyte. Therefore, commercial Sn microparticles show reversible capacity 752 mAh g-1 60 °C after 750 cycles 2 A g-1, much better than case without MDM. exceeds reported data an additive also improves Bi hard carbon. The results provide useful guidance rational selection additives sodium-ion batteries.

Hard carbon (HC), which is one of the anode materials widely used in commercial sodium-ion batteries at present, suffers from a thick and unstable solid electrolyte interface (SEI) layer formed by self-reduction traditional carbonate-based electrolytes on its surface. This phenomenon impacts battery’s Coulomb efficiency, cycle stability, rate performance. In this paper, pyrrolidinium-type di-cation ionic liquid, butyl-1,4-di(methylpyrrolidinium) di[hexafluorophosphate] (C4di[mPy].di[PF6]), studied as an additive to improve interphase stability HC anode. The PF6− C4di[mPy].di[PF6] enhances coordination number between Na+ PF6−, C4di[mPy]2+ preferentially reduced, jointly participating construction stable, thin, dense NaF-rich SEI films, thus laying foundation for improving battery As result, carbonate containing 2 wt% C4di[mPy].di[PF6], reversible capacity HC/Na half-cell increased 14.7%, retention remains 90.4% after 400 cycles. work provides reference future research design high-performance ion liquid additives.
