SULFUR ELECTRODE FOR ANODE OF LITHIUM SECONDARY BATTERY AND PROCESS FOR PRODUCING THE SAME

摘要

PURPOSE: Provided is a sulfur electrode for an anode of a lithium secondary battery, which is produced by adding nickel as an electric conductor to a sulfur electrode material, therefore, it can improve the lifetime of the lithium secondary battery. CONSTITUTION: The sulfur electrode is produced by a process comprising the steps of: mixing 10-90% (based on the total composition of the sulfur electrode) of sulfur powder as an active material and carbon powder and 10-30% (based on the total composition of the sulfur electrode) of the nickel powder as electric conductors under the inert atmosphere; stirring the mixture powder with polyethylene oxide in a solvent such as acetonitrile to make a slurry for the anode; and drying the slurry.
