A team from the University of Technology, Sydney (Australia) and Gyeongsang National University (S. Korea) have developed SnO2@graphene nanocomposites for use as anodes in sodium-ion (Na-ion) batteries. The nanocomposite exhibited a high reversible sodium storage capacity of above 700 mAh g-1 and excellent cyclability, which the researchers ascribed to the 3D architecture of the SnO2@graphene nanocomposite.
The material also demonstrated a good high rate capability for reversible sodium storage.
To the best of our knowledge, this is the best performance among all reported anode materials for Na-ion batteries.—Su et al.
Their paper is published in the RSC journal Chemical Communications.
