Lithium 2-trifluoromethyl-4,5-dicyanoimidazole as a supporting salt in electrolytes achieves a reduced Li2S8 solubility by tuning the chemical production to Li4S8 dimer. Ab initio molecular dynamics and nuclear magnetic resonance calculation confirms the solvation structure radius increase by 20%. Combined with Li2S8 and LiNO3, the electrolyte can demonstrate a stable 300 cycling battery of practical sulfur loading.
