Nickel titanate lithium-ion battery anodes with high reversible capacity and high-rate long-cycle life performance

Abstract

We demonstrate the impressive performance of sparsely studied nickel titanate anode materials for Li-ion batteries (LIBs). The nickel titanate anode delivers a high reversible discharge capacity of 435 mA h g⁻¹ at a current density of 35 mA g⁻¹, high-rate performance and excellent cycling retention of 96% with a long-term cycling stability at 1500 mA g⁻¹ over 300 cycles. The coulombic efficiency is obtained as high as 98%. This superior nickel titanate electrode material could be used as a safe, low-cost, long cycle life anode material for next-generation LIBs with a high power capability.
