Abstract

To meet two goals of low cost and sustainability for battery fabrication, a SnO2 nanoparticles embedded biochar (biochar/SnO2) composite was fabricated using agriculture waste via a facile two-step hydrothermal and sintering method. The as prepared biochar/SnO2 showed a uniform SnO2 distribution in biochar. As a result, a high specific capacity of 577 mAh/g was obtained after 100 cycles, which is much higher than pristine SnO2 nanoparticles and biochar. The significant improvement of specific capacity and cycle stability could be attributed to the nature hierarchical porous structure from biochar, which provided a high surface area and a volume buffer for SnO2 during battery operation.
