Carbon-based transition-metal oxides are considered as an appropriate anode material candidate for lithiumion batteries. Herein, a simple and scalable dry production process is developed to produce carbon-encapsulated 3D netlike FeOx/C materials. The process is simply associated with the pyrolysis of a solid carbon source, such as filter paper, adsorbed with ferrite nitrate. The carbon derived from filter paper induces a carbothermal reduction to form metallic Fe, the addition of carbon and iron increase the conductivity of this material. As expected, this 3D net-like FeOx/C composite delivers an excellent charge capacity of 851.3 mAhg(-1) after 50 cycles at 0.2 Ag-1 as well as high stability and rate performance of 714.7 mAhg(-1) after 300 cycles at 1 Ag-1. Superior performance, harmlessness, low costs, and high yield may greatly stimulate the practical application of the products as anode materials in lithium-ion batteries.
