AI Article Synopsis
- The chemistry of fluorinated organosilane polycondensation helps create a strong silicon anode coated with a fluorine-doped silicon oxide/carbon composite.
- Fluorine doping enhances the formation of a coating with less electrochemically active silicon, as well as a lithium fluoride-rich solid electrolyte interphase.
- This results in a silicon anode that maintains its performance for up to 500 charge cycles at high current densities, making it effective for lithium storage.
Article Abstract
The chemistry of fluorinated organosilane polycondensation is utilized to form a robust Si anode with F-doped SiO/C composite coating. F-doping promotes the formation of not only a coating rich in less electrochemically active Si 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.
