Abstract:

The graphene sheets were anchored into three-dimensional porous foam materials with the in situ polymerization of phenolic resin, and their structures were optimized. Then, after the carbonization and doping tin dioxide, their lithium storage properties were studied. The morphology and crystal structure were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The influence of different phenolic resin dosages on the morphology of three-dimensional graphene foam and tin dioxide-doped samples was studied. The results showed that when 0.1 g resorcinol and 0.2 g glutaraldehyde were used, the three-dimensional graphene foam with the best morphology could be obtained with high specific capacity and cyclic stability after carbonization. After doping tin dioxide, the charge-discharge specific capacity was further improved, and the charge-discharge specific capacity reached 360 mAh/g over 100 cycles.
