Abstract

Abstract : Fast reaction kinetics and excellent performance were achieved in 2D laminate Li3 VO4 /C prepared via a scalable and economical biomass-aided approach. Abstract : Li3 VO4 is a new insertion type anode material with combined merits of high capacity and safety, demonstrating great potential in Li-ion batteries. However, its practical application is hindered by unscalable fabrication coupled with particular challenges in morphology regulation and unsatisfactory rate capability. Here, a 2D laminate Li3 VO4 /C anode is first constructed via a concise, low-cost, and environment-friendly biomass-aided approach. Li3 VO4 /C shows robust pseudocapacitive Li-ion storage, rendering high capacity and excellent rate capability. After 4 periodic rate performance testing from 0.1 to 2.0 A g −1 over 330 cycles, a high reversible capacity of 612.0 mA h g −1 can be reverted. The excellent performance of the 2D laminate Li3 VO4 /C and the scalable fabrication approach will advance the practical applications of Li3 VO4 .
