Abstract
Durability, rate capability, capacity and tap density are paramount performance metrics for promising anode materials, especially for sodium ion batteries. Herein, a carbon free mesoporous CoTiO 3 micro-prism with a high tap density (1.8 g cm −3) is newly developed by using a novel Co-Ti-bimetal organic framework (BMOF) as precursor. It is also interesting to find that the Co-Ti-BMOF derived carbon-free mesoporous CoTiO 3 micro-prisms deliver a superior stable and more powerful Na + storage than other similar reported titania, titanate and their carbon composites. Its achieved capacity retention ratio for 2,000 cycles is up to 90.1% at 5 A g −1.
