Na3VO4 as a new anode material for lithium-ion batteries

Sodium vanadate, Na3VO4, is prepared for the first time as a new anode material for lithium-ion batteries (LIBs), showing satisfactory capacity, an ultra-long cycle life and excellent rate capability. When cycling at a current of 0.1 A g(-1), the Na3VO4 electrode delivers a high reversible capacity of 535.2 mA h g(-1) after 610 cycles. Then cycling at a current of 1 A g(-1), the Na3VO4 electrode still retains a discharge capacity of 208 mA h g(-1) after 2000 cycles. After rate performance testing from 0.1 to 1.6 A g(-1) over 210 cycles, the Na3VO4 electrode retains a satisfactory capacity of 350 mA h g(-1), when the current returns to 0.1 A g(-1). The superior comprehensive electrochemical performance and low cost of Na3VO4 endow it with great potential for practical applications in LIBs.
