Made in IndiaMeet PoroSil™
More energy.Same footprint.
PoroSil™ helps cell developers move beyond graphite without inheriting untreated silicon’s mechanical instability. Developed from a decade of research at IIT Bhubaneswar and produced at our pilot plant in Odisha.
- Higher capacity — 1,350 mAh/g reported, about 3.6× conventional graphite.
- Built for stability — porous structure absorbs expansion during charging.
- Drop-in integration — blends with graphite in standard slurry workflows.
- Faster charging — designed for better charge acceptance than graphite-only anodes.
Engineered advantages
Capacity, conductivityand room to breathe.
Three design choices make PoroSil™ practical for real cells — not just laboratory capacity.
01
Controlled Expansion
Porous, micron-scale silicon provides internal space to accommodate volume change during lithiation — so particles don’t crack.
02
Reliable Conductivity
A carbon-coated composite architecture maintains electrical pathways between active particles, cycle after cycle.
03
Practical Integration
Si–C powder blends with graphite through conventional electrode-slurry preparation — no new production line needed.
Reported performance
A practical stepbeyond graphite.
Even a modest 10% PoroSil™ blend delivers a measurable gain — without relying on a high silicon loading.
