Porous carbon networks containing Si and SnO2 as high performance anode materials for lithium-ion batteries
چکیده انگلیسی
Porous carbon networks containing Si and SnO2were synthesized by annealing the films formed by knife coating suspension with Si, SnCl2, polyacrylonitrile (PAN), poly(methyl methacrylate) (PMMA) and N,N-Dimethylformamide (DMF) in vacuum. The Si-SnO2-C composite was constructed by interconnected amorphous carbon branches containing nano-pores with a size of 1-5 nm, Si and SnO2 nano-particles with a size of 30-50 nm. The composite demonstrates high performance as lithium-ion batteries (LIBs) anode. It delivers a high capacity of 1359.12 mA h g−1after 200 cycling at a current density of 0.5 A g−1and excellent rate capability of 512.16 mA h g−1at a current density up to 20 A g−1.
