摘要
The present invention relates to a method for manufacturing a sulfur-selenium-carbon complex. The method comprises steps of: (1) mixing selenium and carbon material and heat treating the same with microwave to form a selenium-carbon complex; and (2) mixing sulfur with the formed selenium-carbon complex and heat-treating the same with microwave to form the sulfur-selenium-carbon complex, wherein a heat treatment of the step (1) is performed at a higher temperature than a heat treatment of the step (2). The sulfur-selenium-carbon complex according to the present invention has an effect of improving electrical conductivity of a battery and alleviating overvoltage during a discharge process.
