Abstract
- Hollow structured CoFe<subscript>2</subscript>O<subscript>4</subscript> nanospheres were synthesized by a hydrothermal method. The uniform hollow nanosphere architecture of the as-prepared CoFe<subscript>2</subscript>O<subscript>4</subscript> has been confirmed by field emission scanning electron microscopy and transmission electron microscopy analysis, which give an outer diameter of 200-300 nm and a wall thickness of about 100 nm. CoFe<subscript>2</subscript>O<subscript>4</subscript> nanospheres exhibited a high reversible capacity of 1266 mA h g<superscript>-1</superscript> with an excellent capacity retention of 93.6% over 50 cycles and an improved rate capability. CoFe<subscript>2</subscript>O<subscript>4</subscript> could be a promising high capacity anode material for lithium ion batteries. [ABSTRACT FROM AUTHOR]
