MnO2 nanotube/GO composite anode for high performance lithium-ion capacitor
Li-ion capacitors (LICs) have emerged as promising energy storage devices within the electronic industry. The performance of LICs is predominantly influenced by the electrode material utilized, making the proper selection and development of said material of utmost importance. This study focuses on fabricating a composite electrode material using a simple, cost-effective, and environmentally friendly technique, combining Manganese dioxide (MnO2) nanotube and graphene oxide (GO). The low cost, high natural abundance, and high theoretical specific capacity (1230 mAh/g) of MnO2 enables it to be effectively used in energy storage systems. The resulting material showcases a distinctive architecture where MnO2 nanotube nanorods are enveloped by GO nanosheets. By employing a binder-free buckypaper approach, the MnO2 nanotube/GO composite anode exhibits exceptional electrochemical performance, including high energy (213.29 Wh/kg) and power density (28.5 kW/kg), improved rate capability, and excellent cyclic stability. These findings undoubtedly indicate a promising future for the MnO2 nanotube/GO composite anode in lithium-ion-based energy storage systems.
