Resultant Material

We report an effective approach to fabricate layered-spinel capped nanotube assembled 3D Li-rich hierarchitectures as a cathode material for Li-ion batteries. The resultant material exhibits a reduced first-cycle irreversible capacity loss, rapid Li-ion diffusion rate and excellent cycle stability.

Highly ordered spherical LiFePO4 is synthesized by an intermittent microwave heating assisted water-bath reaction and the resulted LiFePO4 shows high tap-density of 2.0 g cm-3 and volumetric specific capacity of 325 mAh cm-3 when used as cathode material in Li-ion battery. The high performance of the ordered spherical LiFePO4 is explained in terms of the high conductivity and the improved mass transfer kinetics. Such highly ordered spherical LiFePO4 with improved volumetric specific capacity will be potentially used in the high-power Li-ion batteries for electric vehicles.
