Electrochemical lithium insertion into vanadia nanotubes

Vanadium oxide nanotubes are promising as cathode material for lithium-ion batteries, this unique material demonstrated the discharge capacity to be about 260 mAh/g. The decrease of discharge capacity of material with number of cycle was accompanied by degradation of tubular-like micromorphology. Analysis of tubular and planar nanostructures by EXAFS, EELS and electrochemical techniques showed that the nanotubes whose are more active electrochemically degrade quicker than planar structures because of the loss of long-range order.
