Mesoporous VO2 nanowires with excellent cycling stability and enhanced rate capability for lithium batteries

Abstract

To combine the merits of the one-dimensional structure and the porous structure, mesoporous VO₂ nanowires have been designed and reported for the first time. Excellent cycling stability and enhanced rate performance are obtained and may be attributed to the mesoporous nanowires, realizing both high surface area for more active sites and facile stress relaxation resulting in excellent structure stability. Our results demonstrate that the mesoporous nanowires are favourable for high-rate and long-life lithium batteries.
