NaV 3 O 8 nanoplates with a thickness of approximately 50–200 nm, a length of 1–3 μm, and a width of 0.2–1 μm have been fabricated by using an in situ template method. When used as a cathode material for Li‐ion batteries (LIBs), the as‐synthesized NaV 3 O 8 nanoplates delivered a high reversible capacity of 230 mAh g −1 , with a capacity retention of 93.4 % for up to 200 cycles. Furthermore, about 50 % of its regular capacity can be retained even at a high current density of 6.4 A g −1 (ca. 21.3 C). The superior electrochemical performances are attributed to the fast lithium‐ion diffusion kinetics and good structural stability. The excellent Li‐storage properties, including high capacity, superior high‐rate performance, and long cycle life, demonstrate that NaV 3 O 8 nanoplates can serve as a potential candidate for the cathode materials of Li‐ion batteries.
