Description
Atomfair Mesoporous Nano Carbon for Lithium-Sulfur Battery (10g)
Product Overview
Rechargeable lithium–sulfur (Li–S) batteries are recognized as one of the most promising next-generation energy storage systems, attributed to the low cost and high specific energy of sulfur cathodes. However, their commercialization is constrained by critical challenges: dissolution of lithium polysulfides (Li₂Sₓ, x>3) in electrolytes, significant volumetric expansion (80%) of sulfur during lithiation, and poor electronic/ionic conductivity of sulfur and lithium sulfide (Li₂S).
Atomfair’s mesoporous nano carbon is engineered to address these pain points. With its large specific surface area, ordered pore structure, excellent electrical conductivity, and structural stability, it effectively enhances sulfur utilization, inhibits polysulfide diffusion, and improves the overall cycling performance and reliability of Li–S batteries.
Key Advantages
- High Sulfur Loading Capacity: Large specific surface area (232 m²/g) and pore volume enable theoretical sulfur loading up to 90 wt%, maximizing battery energy density.
- Polysulfide Trapping: Ordered mesoporous structure physically and chemically inhibits the diffusion of lithium polysulfides (Li₂Sₓ, x>3), mitigating the “shuttle effect”.
- Enhanced Conductivity: Excellent electrical conductivity facilitates efficient ion/electron transport, addressing the poor conductivity of sulfur and Li₂S.
- Volume Expansion Mitigation: Rigid yet adaptable structure accommodates sulfur’s 80% volumetric expansion during lithiation, maintaining electrode integrity.
- Superior Electrochemical Performance: Optimizes cycling stability, rate capability, and long-term reliability of Li–S battery cathode composites.
