Sn nanoparticles embedded into porous hydrogel-derived pyrolytic carbon as composite anode materials for lithium-ion batteries
文献摘要：
The composite powders,Sn nanoparticles embedded into the porous hydrogel-derived carbon(Sn@PHDC),were successfully prepared by polymerization and calcination processes,and the characterization results confirmed that Sn nanoparticles were homogeneously dis-persed in the porous hydrogel-derived pyrolytic carbon.The coin cell assembled with the Sn@PHDC-50 composite electrode presented good cyclic stability and rate perfor-mance when the weight ratio of Sn nanoparticles to hydro-gel-derived pyrolytic carbon was maintained at 1∶1.Moreover,the Sn@PHDC-50 electrode manifested a lower charge transfer resistance of 58.57 Ω and a higher lithium ions diffusion coefficient of 1.117×10-14 cm2·s-1 than pure Sn and other Sn@PHDC electrodes.Those improve-ments can be partly ascribed to the fact that the hydrogel-derived pyrolytic carbon matrix can release the volume strain and enhance the electronic conductivity of the composite electrode,and partly to the fact that the porous hydrogel-derived pyrolytic carbon matrix can suppress agglomera-tions of Sn nanoparticles and shorten Li+diffusion paths.This work may provide a new approach for the improvement of Sn-based anode materials for lithium-ion batteries.
