The mechanism of the one-step synthesis of hollow-structured Li ₃VO₄ as an anode for lithium-ion batteries

In recent years, the controlled synthesis of inorganic micro- and nanostructures with hollow interiors has attracted considerable attention because of their widespread potential applications. A feasible method for synthesizing Li₃VO₄ by a template-free, solution synthesis of single-crystalline microboxes with well-defined non-spherical morphologies has been reported. This study provides the useful information to produce other hollow structure materials to the broad audience of readers. The formation of hollow structure and the influence of raw materials have been presented. The thus-synthesized Li₃VO₄ exhibited significantly improved conductivity, rate capability, and cycling life compared to commercial graphite, synthesized Li₄Ti₅O₁₂, and previously reported Li₃VO₄. A feasible method for synthesizing Li ₃VO₄ by a template-free, solution synthesis of single-crystalline microboxes with well-defined non-spherical morphologies is reported (see figure). The formation of hollow structures and the influence of raw materials are presented. The thus-synthesized Li₃VO₄ exhibited significantly improved electrochemical performance.
