Description
xCell Lab Silicon Oxide (1600) – Lithium-Ion Battery Anode Material [CVD-Coated SiOx | 1600 mAh/g]
High-capacity carbon-coated silicon oxide anode for next-generation energy storage
The Cell Lab™ Silicon Oxide (SiOx 1600) is a high-performance lithium-ion battery anode material featuring a carbon-coated SiOx composite structure produced through Chemical Vapour Deposition (CVD). Engineered for superior energy density and cycle stability, this advanced material offers a first-cycle reversible capacity exceeding 1600 mAh/g—significantly outperforming conventional graphite anodes.
Designed for battery R&D, prototyping, and pilot-scale cell manufacturing, SiOx (1600) enhances lithium storage capacity, structural stability, and conductivity, making it a key material for next-generation EV and solid-state battery research.
Key Features
• High Specific Capacity (≈1600 mAh/g)
Delivers more than four times the reversible capacity of standard graphite, boosting overall cell energy density.
• Carbon-Coated SiOx Core
CVD carbon coating improves electronic conductivity and mechanical flexibility, reducing particle fracture during cycling.
• Optimised Particle Morphology
Average particle size of 5 µm with uniform distribution ensures efficient electrode slurry dispersion and smooth coating behaviour.
• Excellent Processing Compatibility
Ideal for use with standard binder systems such as PVDF or LA133 and compatible with NMP and water-based electrode fabrication.
• High Purity and Stability
Low surface area and moisture absorption enhance oxidation resistance and long-term electrode integrity.

FAQ
Q1: What advantage does SiOx (1600) offer over traditional graphite anodes?
A1: It offers much higher specific capacity (≈1600 mAh/g vs. 370 mAh/g for graphite) and better cycle stability when paired with advanced binders or prelithiation techniques.
Q2: Is carbon coating necessary for performance?
A2: Yes, the carbon layer enhances conductivity and reduces irreversible lithium loss during the first cycle.
Q3: Can SiOx (1600) be blended with graphite?
A3: Absolutely—blending (typically 5–20 wt%) improves cycle life and reduces expansion stress.
Q4: What slurry system is recommended?
A4: Compatible with PVDF/NMP and LA133/water-based systems. Ensure thorough mixing and controlled viscosity.
Q5: What precautions are required during storage?
A5: Store in a moisture-free, vacuum-sealed environment. Avoid exposure to air or humidity to prevent surface oxidation.
