Flexible potassium vanadate nanowires on Ti fabric as a binder-free cathode for high-performance advanced lithium-ion battery

A facile and scalable strategy, based on a hydrothermal route, has been applied to fabricate potassium vanadate (KVO) nanowires on Ti fabric. The morphology, crystal structure, chemical composition of the prepared sample are tested and presented in detail. When tested as cathode materials for lithium-ion batteries, the flexible KVO electrode has a high reversible capacity of 270 mAh g(-1) at a current density of 100 mA g(-1) after 300 cycles. Furthermore, the KVO delivers outstanding rate behavior, even at 960 mA g(-1), a reversible capacity as high as 214.1 mAh g(-1) can be retained. The superior electrochemical performance suggests that the KVO nanowires on Ti fabric can be as a potential cathode candidate for flexible rechargeable lithium-ion batteries. (C) 2016 Elsevier B.V.
