Description
xCell Lab Sulphur–Carbon Composite Cathode Material [10 g, for High-Performance Lithium–Sulphur Batteries] – High-Capacity Sulphur Cathode for Next-Generation Energy Storage
Advanced sulphur–carbon composite optimised for high-energy lithium–sulphur battery research
The Cell Lab Sulphur–Carbon Composite Cathode Material is an advanced cathode powder designed for lithium–sulphur (Li–S) battery R&D. Engineered to overcome the key limitations of Li–S systems — such as polysulphide dissolution, volume expansion, and the low intrinsic conductivity of sulphur — this composite delivers enhanced electrical conductivity, stable cycling, and high reversible capacity.
Containing 75 wt% sulphur (customisable between 30–80%), this material achieves up to 1180 mAh/g at 0.1C, with excellent retention of 860 mAh/g after 100 cycles at 0.2C. It is pre-optimised for coin cell assembly and compatible with standard electrolytes and binders, making it ideal for both academic and industrial Li–S battery research.

FAQ
Q1: What is the optimal sulphur content for high-performance Li–S cells?
Typically 70–80 wt% delivers the best balance between energy density and cycling stability.
Q2: Is this material compatible with standard Li–S electrolytes?
Yes. It performs well with ether-based electrolytes such as DOL/DME and additives like LiNO₃.
Q3: Can this be used directly for electrode preparation?
Yes. It can be mixed directly with PVDF and conductive carbon in NMP to form a homogeneous slurry.
Q4: Is it suitable for pouch or cylindrical cells?
Yes. The composite can be scaled for various cell formats depending on the slurry coating and loading.
Q5: Can sulphur content or particle size be customised?
Yes. Cell Lab offers tailored formulations (30–80 wt% S) and particle size adjustments upon request.
