STUDY ON CARBON FROM PYROLYZING PHENOL-FORMADEHYDE RESIN FOR AN ANODE OF LITHIUM ION BATTERY

Carbon anode for a lithium ion battery was prepared by low temperature ( 600 ℃ ～ 1 600 ℃ ) pyrolysis of commercial thermoplastic phenol formaldhyde resin. Elemental analyses of pyrolytic carbon were investigated. X ray diffraction pattern and the constant current charge discharge properties of pyrolytic carbonaceous materials were stuied. Results showed that the pyrolytic carbonaceous materials became structurally order, and the first charge discharge special capacities reduced with increasing pyrolytic temperature. The specific capacities depended on pyrolytic temperature and hydrogen content.
