HIGH-PERFORMANCE CATHODE MATERIALS FOR LITHIUM SULFUR BATTERIES FROM LIGNOSULFONATE |
摘要 |
Methods of making cathodes for lithium-sulfur batteries are disclosed, in addition to cathodes and batteries containing the cathodes. A method of making a cathode is disclosed which includes extracting lignosulfonate from brown liquor, pyrolyzing the lignosulfonate, carbonizing the pyrolyzed lignosulfonate to form a carbon-sulfur compound, and forming the carbon-sulfur compound into a cathode. A cathode for a lithium-sulfur battery is disclosed which includes pyrolized lignosulfonate recovered from brown liquor, and carbon. The pyrolized lignosulfonate and carbon are suspended in a matrix having a substantially homogenous distribution of sulfur. A battery is disclosed in which an anode including an electrolye, lithium, is provided along with a membrane separate and a carbon comprising a carbon-sulfur compound derived from lignosulfonates. |
