Safe batteries: Ethoxy(pentafluoro)cyclotriphosphazene additive for carbonate electrolytes is discovered to offer multiple important benefits for SiO_x-graphite/NMC811 lithium-ion batteries: synergistic effect for flame retardancy with LiPF₆ rendering electrolyte non-flammable at relatively low additive concentration, stabilization of Si-based anodes due to contribution to solid-electrolyte interphase, and improved electrolyte wetting of polyolefin separators.

多功能添加剂乙氧基（五氟）环三磷腈为 SiOx-石墨/NMC811 电池提供安全的碳酸盐电解质

安全电池：用于碳酸酯电解质的乙氧基（五氟）环三磷腈添加剂被发现可为 SiO _x -石墨/NMC811 锂离子电池提供多种重要优势：与 LiPF ₆的阻燃协同效应使电解质在相对较低的添加剂浓度下不易燃，由于对固体电解质界面的贡献，硅基阳极变得稳定，并改善了聚烯烃隔膜的电解质润湿性。
