摘要

利用氟化有机硅烷缩聚的化学性质，在掺f的SiOx/C复合涂层上形成坚固的Si阳极。f掺杂不仅促进了富含电化学活性较低的Si4+物质的涂层的形成，而且还促进了富含lif的固态电解质界面的形成，使Si阳极在大电流密度下具有500次循环的长寿命，用于锂存储。

Fluorinated organosilane polycondensation enables a robust Si anode for lithium storage†

The chemistry of fluorinated organosilane polycondensation is utilized to form a robust Si anode with F-doped SiO_x/C composite coating. F-doping promotes the formation of not only a coating rich in less electrochemically active Si⁴⁺ species but also an LiF-rich solid-state electrolyte interphase, enabling an Si anode with a long life of 500 cycles at large current densities for lithium storage.
