Abstract:Due to its quite high theoretical specific-energy density, FeF2 nanomaterial is a good candidate for the cathode material of lithium-ion batteries. The preparation of FeF2 nanomaterial is very important for its application. At present, the preparation process mostly involves high temperature and an inert atmosphere, which need special or expensive devices. It is very important to seek a low-temperature and mild method, without the need for high temperature and inert atmosphere, for the preparation and followin… Show more
This study introduces an FeSiF6 additive synthesized via the reaction of HF with Si–Fe alloys. It prevents crystalline Li15Si4 formation and promotes stable SEI film, significantly enhancing the cycling stability of silicon-based anodes.
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.
