A novel N-doped organic porous carbon derive from water-based alkyd resin for lithium ion battery anode materials

Nitrogen-doped aqueous alkyd resin carbons are prepared by polymerization methods with biorenewable, biodegradable, and cheap raw materials (soybean oil) as precursor, and NH3 center dot H2O as nitrogen source, and ZnCl2 as template pore-forming agent, followed by carbonization process. The effect of carbonization temperature on the pore structures and electrochemical properties of nitrogen-doped aqueous alkyd resin carbons is studied. Carbon materials prepared at higher carbonization temperature (PC-800) exhibits the higher graphitization and better porosity. The PC-800 maintains a high discharge specific capacity after 300 charge and discharge at a low current density. In addition, it shows good cycling stability, high rate capability and excellent reversible capacity, due to the good pore structure and N doping. Nitrogen-doped aqueous alkyd resin carbons with superior electrochemical performances as anode active material of lithium ion battery provide a new strategy to solve energy shortages.
