Preparation and application of energy materials from biomass

Silicon-based anode materials in recent years has gained tremendous interest due to high theoretical specific capacity for next generation lithium ion battery. Some biomass, such as rice husks (RHs), has contained a lot of inorganic silicon, which are abundant in all the countryside and farmland. Considering that RHs are mainly composed of organic lignin, cellulose, hemicellulose, and inorganic Si compound, they could be used to prepare low-cost electrode materials, such as carbonaceous and silicon-based anode materials. In this work, we will present the synthesis of various anode materials from RHs with prominent performance for lithium ion battery application, such as porous C/SiO[Formula: see text] composites and Al-doped porous carbonized RHs husks composites.
