Surface Modification with F-Doped Carbon Layer Coating on Natural Graphite Anode for Improving Interface Compatibility and Electrochemical Performance of Lithium-Ion Capacitors
Abstract:F-doped carbon layer coating is an effective surface
modification
method to enhance the intrinsic conductivity of active materials and
facilitate the accommodation of solvated Li+ ions near
the carbon surface. Furthermore, it induces the formation of an effective
LiF-rich solid electrolyte interface with high electrochemical stability
and facile surface diffusion of Li+ ion owing to its low
energy barrier. Therefore, by employing a cost-effective coating material
poly(vinylidene fluoride) (PVDF), high electroc… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
