Characteristics of electrolytes for silicon based anodes

Silicon is currently considered the most promising negative electrode material for next-generation high-energy lithium-ion batteries due to its high volumetric and gravimetric capacity, low cost, and good availability. The major obstacle hindering its wide commercial application so far, is the insufficient cycle life caused by enormous volumetric changes during lithiation and delithiation, resulting in pulverization, electronic contact loss and recurring breakage and reformation of the solid electrolyte interphase in every cycle.

Application fields of electrolytes for silicon based anodes

E-Lytes electrolytes for silicon-based anodes are designed to enable a long-cycle life via the formation of a highly efficient solid electrolyte interphase that is flexible enough to withstand the expansion/shrinkage of silicon particles, thereby reducing the irreversible electrolyte and lithium consumption significantly. The electrolyte formulations contain optimized salt and solvent mixtures that are combined with synergistically working film-forming additives. The electrolytes are suitable for pure silicon, silicon/graphite blends, as well as silicon suboxides (SiOx with x≈1) containing electrodes.
