Abstract

Ultra-thin SiO_x (0 < x < 2) nanosheets were obtained via a convenient solvothermal route from a Zintl compound CaSi₂. After carbon coating, the SiO_x@C nanosheet anodes exhibit high capacity, good rate and superior cycling performance for high-capacity lithium ion battery applications. The specific capacity can be maintained as high as 760 mA h g⁻¹ with almost no capacity decay after 400 cycles at a current density of 0.5 A g⁻¹.
