Abstract
Energy storage materials with high energy density are highly desired due to the development of electrical vehicles. In this work, monomer aniline is driven to be carbon by a simple liquid deposition and carbonization. The C/MnO nanocomposite with a non-linear contact interface core–shell structure were successfully fabricated. It contains 92.5 wt% of MnO for the dry nanocomposite. When evaluate as anode materials for lithium ion battery, the C/MnO electrode exhibits excellent reversible capacity of 943.6 mAh g−1 at a current density of 100 mA g−1 after 100 cycles. Impressively, a capacity of 484 mAh g−1 retains at a high current density of 4000 mA g−1, indicating that the C/MnO nanocomposite is potential competitor for application in lithium ion battery.
