Abstract
With the fast development of lithium secondary battery, LiVPO4F, a new class of cathode materials for lithium ion battery, was synthesized by solid-state reaction firstly. LiVPO4F is a promising cathode material for lithium ion battery with high specific energy and excellent thermal stability. It is therefore anticipated having great potential in application of power battery for high efficiency energy storage.based on a short summarizing of the present cathode material systems, the specialty and latest research rogress on material preparation, structure analysis, electrochemical performance and energy storage mechanism of LiVPO4F were comprehensively reviewed, and the future perspective was finally concluded.
