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.
