The anion-solvent interactions in Li-ion batteries were promoted in ether-based electrolyte by applying the small-anion-size LiNO₃ and tetrahydrofuran with a high ratio of dipole moment to dielectric constant. The designed ether-based electrolyte showed optimized interphasial stability on the pure-SiO_x anode and NMC811 cathode, thus enabling stable cycling performance of the pure-SiO_x||NMC811 full cell over 500 cycles.
