Enhanced Lithium Storage Performance of α-MoO₃/CNTs Composite Cathode.

ABSTRACT: Orthorhombic molybdenum oxide (α-MoO₃), as a one-layered pseudocapacitive material, has attracted widespread attention due to its high theoretical lithium storage specific capacity (279 mAh/g) for lithium-ion batteries' cathode. Nevertheless, low conductivity, slack reaction kinetics, and large volume change during Li⁺ ions intercalation and deintercalation seriously limit the practical application of α-MoO₃. Herein, we added a small number of CNTs (1.76%) to solve these problems in a one-step hydrothermal process for preparing the α-MoO₃/CNTs composite. Because of the influence of CNTs, the α-MoO₃ nanobelt in the α-MoO₃/CNTs composite had a larger interlayer spacing, which provided more active sites and faster reaction kine
