Bi2O3 is a promising sodium storage material due to its high gravimetric specific capacity. However, Bi2O3 possesses lower electrochemical performance due to its poor electrical conductivity and structural integrity during Na+ insertion/extraction process. Here, we prepared a carbon coated Bi2O3 nanocomposite by a redox reaction and a carbon coating process. In this nanocomposite, the carbon layer...
A composite consisting of Bi2O3 nanoparticles encapsulated by three-dimensional (3D) porous nitrogen-doped graphene is reported. Due to the 3D porous structure, the composite has large specific surface area of 112 m2 g−1, which can increase the contact area between active material and electrolyte. In addition, the 3D porous conductive framework can not only facilitate the fast electron transport and...
