Graphite–Silicon Composites
Ready-to-blend graphite–silicon anode material
Silicon blended with graphite for an instant capacity boost — using the same slurry, coating and electrode processes cell makers already run today.

from silicon

Every cell formatThe easiest upgrade
Same process.More capacity.
Switching anode chemistry usually means new equipment and long requalification. Our Graphite–Silicon Composites keep the graphite you already know and add silicon for more capacity — the fastest, lowest-risk route to higher-energy cells.
- Drop-in ready — works on conventional slurry and electrode lines.
- Instant capacity gain — a modest silicon share lifts anode capacity measurably.
- Cost-effective — more energy without a full material switch.
- Made in India — produced at our Si anode pilot plant in Odisha.
Why blend
The practical pathbeyond graphite.
Built for cell makers who want higher energy now — without redesigning their production.
No Line Changes
Uses standard mixing, coating and calendering — existing equipment and know-how stay the same.
Familiar Behaviour
Graphite remains the main matrix, so handling and electrode behaviour stay close to what your team already runs.
Measurable Gain
Even a 10% silicon share is modelled to lift anode capacity by about 28.6% — more energy in the same cell.
