Products Description
Mesoporous Carbon Materials for Lithium-Sulfur Battery Cathode
Mesoporous carbon features a high specific surface area and large pore volume, along with excellent electrical conductivity and structural stability. Its well-controlled mesopore size distribution and ordered pore structure enhance sulfur utilization and improve the cycling stability of batteries. Composites made from ordered mesoporous carbon and sulfur tend to deliver superior electrochemical performance.Small mesopores primarily hold the active material and help limit polysulfide ion diffusion, while interconnected large cylindrical mesopores promote efficient lithium-ion transport during charge and discharge cycles.
Additionally, the material’s high pore volume allows for increased sulfur loading, and optimizing sulfur content can boost initial discharge capacity and enhance cycling life.
Technical Parameters
Mode:XW-HPC，Packing: 10g/bag
Physical parameters of mesoporous carbon materials:
1.HPC features a porous structure with pore diameters around 130–150 nm and thin walls of approximately 15 nm. It is a partially graphitized, disordered carbon with a uniform surface distribution of carbon, oxygen, and nitrogen.
2.The material has a specific surface area of 232 m²/g, measured by mercury intrusion porosimetry (Figure 2a). Its total pore volume for pores under 200 nm is 2.51 cm³/g, enabling a theoretical sulfur loading of up to 90 wt.%.
3.The tap density is 0.146 g/cm³. According to laser particle size distribution testing, D(10) is 3.689 μm, D(50) is 10.429 μm, and D(99) is 27.902 μm. These particle size characteristics make the material compatible with standard lithium battery slurry preparation and coating processes.
