Mn3O4 nanowires with diameter of similar to 15 nm and a length of up to several micrometres have been hydrothermally synthesized at 200 degrees C for 15 h without any surfactants. It was investigated that during the formation process of Mn3O4 nanowires the length of the nanowires increased while the diameter did not obviously change. The coercivity of the Mn3O4 nanowires is up to 5600 Oe at 5 K. As these Mn3O4 nanowires were treated with LiOH by solid state reaction at 750 degrees C for 6 h, interconnected LiMn2O4 polyhedrons were obtained. The achieved discharge capacity of the LiMn2O4 polyhedrons was 115 mAh g(-1) and they retained 98.3% of this capacity after 60 cycles at 0.1 C.
