Abstract
A sulfur-carbon composite for controlling the particle size of the sulfur-carbon composite to a specific range and a method for preparing the same.
Claims20
A method for preparing a sulfur-carbon composite comprising:
- (a) mixing sulfur with a porous carbon material;
- and
- (b) heat-treating the mixed porous carbon material and sulfur to prepare the sulfur-carbon composite,
- wherein a particle size (based on D50) of the sulfur-carbon composite is adjusted in the range of 37.25 μm to 70 μm.
1 more element
A sulfur-carbon composite comprising:
- a porous carbon material;
- and
- sulfur on at least part of an inside and a surface of the porous carbon material, wherein a particle size (based on D50) of the sulfur-carbon composite is in the range of 37.25 μm to 70 μm.
