Durable lithium storage of Si anode enabled by semi-embedded integration of SnO2 onto surface

Year: 2025

Type: article

Abstract: Herein, a high-performance Si-based anode (Si@SnO 2 @C) has been obtained by semi-embedded integration of ultrafine SnO 2 nanoparticles onto the surface of cost-effective irregular Si particles and further coated with an ultrathin carbon through a simple route. The results verify that the in-situ conversion of SnO 2 into Li x Sn during lithiation process contributes to superb lithium storage performance of the Si particles, such as high capacity (1071.2 mAh g −1 after 500 cycles at 400 mA g −1 ) and long lifespan (1000 cycles). Finally, this study might be able to offer a viable strategy for facilely preparing Si-based anodes with advanced performance for lithium-ion batteries.
