21_13/2011Lithium-Ion Batteries: Epitaxial Growth of Branched α-Fe2O3/SnO2 Nano-Heterostructures with Improved Lithium-Ion Battery Performance (Adv. Funct. Mater. 13/2011)

Unique branched α-Fe2O3/SnO2 nano-heterostructures with six-fold symmetry are presented by Ting Yu, Hong Jin Fan, and co-workers on page 2439. When used as anode material for lithium-ion batteries, the composite demonstrates superior performance to either of the individual components. The improvement is ascribed to a synergetic effect between the two oxides and the unique feature of the branched structure, which provides an increased specific surface areas.
