Preparation and properties of mesoporous carbon composite as negative electrode materials

Using sodium lignosulfonate as carbon source, microspheres were prepared by ultrasound. Molybdenum disulfide was synthesized directly by hydrothermal method and grown on the surface of lignin microspheres. Then, molybdenum disulfide modified porous microsphere carbon material was prepared by pyrolys...
