Abstract

• An eco-friendly aerosol-assisted chemical deposition (AACD) has been established. • A silicon anode is fabricated by the AACD and is used in lithium-ion batteries. • The features of charge curves are understood through univariate linear regression. Silicon is a promising alternative anode material in lithium-ion batteries as it has a higher theoretical specific capacity than the commercial graphite-based anodes. Within this work, a new multicoated composite material was fabricated through a simple, non-vacuum, and economical aerosol-assisted chemical deposition. This eco-friendly preparation method was developed for the first time with the sodium alginate for a nano-silicon composite. Such a multicoated composite generates excellent electrochemical performance. Our results suggest that the anode delivers a specific capacity of ∼760 mAh g −1 at 0.36 A g −1 after 300 discharge/charge cycles.
