One-Step Synthesis of MnO2 Flower/Carbon Nanotube with Improved Lithium Storage Properties.

This work reports a one-step hydrothermal synthesis of MnO2-flower/Carbon nanotube (CNTs) binary material, featuring a coated-worm like structure. The material showed a specific capacity of 800 mA h g(-1), a working plateau at 0.5 V against a Li+/Li electrode, and ideal stability under a current density of 2 A g(-1). The transition of the crystalline form of MnO2 was also observed when adjusting the ratio of CNTs in the reaction, which may be an intriguing result for the material's future application.
