A method of preparing a cathode material for a lithium-sulphur battery

摘要

The method of preparing a cathode material consisting of a mesoporous carbon support structure with sulphur-filled pores is that during synthesis of the CMK-3 mesoporous carbon structure, the low molecular weight carbon source is incorporated into the solid template SBA-15, the resulting composite is completely carbonized and the template SBA-15 is then removed. As a carbon precursor source, low molecular weight chitosan is incorporated into the solid SBA-15 template, which is also used as a nitrogen source in the concurrent process of doping the carbon structure of the cathode with nitrogen atoms.
