Additive-free synthesis of V(4)O(7) hierarchical structures as high performance cathodes for lithium ion batteries.
Vanadium oxide (VOx) hierarchical structures were controllably synthesized through a solvothermal method in water-ethylene glycol (EG) mixed media. A V4O7 "nanocross" structure is first reported and observed to exhibit exceptional cycling stability at 0.05 A g(-1) and 3.05 A g(-1), which could be a promising cathode candidate for lithium ion batteries.
