Abstract:

© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Low-cost and sustainable sodium-ion batteries are regarded as a promising technology for large-scale energy storage and conversion. The development of high-rate anode materials is highly desirable for sodium-ion batteries. The optimization of mass transport and electron transfer is crucial in the discovery of electrode materials with good high-rate performances. Herein, we report the synthesis of 3D interconnected SnO2/graphene aerogels with a hierarchically porous structure as anode materials for sodium-ion batteries. The unique 3D architecture was prepared by a facile insitu process, during which cross-linked 3D conductive graphene networks with macro-/meso-sized hierarchical pores were formed and SnO2 nanoparticles were dispersed uniformly on the graphene surface simultaneously. Such a 3D functional architecture not only facilitates the electrode-electrolyte interaction but also provides an efficient electron pathway within the graphene networks. When applied as anode materials in sodium-ion batteries, the as-prepared SnO2/graphene aerogel exhibited high reversible capacity, improved cycling performance compared to SnO2, and promising high-rate capability. Explore the pores: 3D SnO2/graphene aerogels with a hierarchically porous structure are prepared by a facile self-assembly method, in which graphene nanosheets self-bridge to form 3D continuous networks with interconnected porous channels and SnO2 nanoparticles are homogeneously loaded on the graphene nanosheets. The integration of SnO2 nanoparticles leads to fast Na⁺ diffusion and electronic conductivity, giving rise to a promising high-rate performance as anode in sodium-ion batteries.
