Abstrakt: In this paper, SiO2@C-Sn/SnO2 nanospheres with core-shell structure were synthesized by the hard template method using resorcinol-formaldehyde resin as a carbon source and the hydrolysis of SnCl4-5H2O. Tin material as lithium battery anode has the advantages of high specific capacity and low voltage plateau. This innovative core-shell structure exhibits excellent electrochemical lithium storage performance, making it an excellent candidate for lithium-ion batteries. After 100 cycles, the material demonstrated a notable reversible capacity of 591.8 mAh g−1 at a current density of 100 mA g−1. In addition, the stability of the core-shell structure provides excellent capacity retention for the battery. [ABSTRACT FROM AUTHOR]
