Powering morewith less.
Higher-capacity PoroSil™ silicon–carbon anodes unlock real gains wherever battery size, weight and runtime define performance — from electric vehicles to defence systems.
Where it matters
One anode material.Six industries transformed.
Every battery-powered product is limited by how much energy fits in a given space and weight. By raising anode capacity while staying compatible with existing cell manufacturing, PoroSil™ helps each of these sectors do more with the same footprint.
Cellark in action01EVs & E-Mobility
More range from thesame battery pack.
Range, charging time and pack cost decide how fast India moves to electric — from two-wheelers and three-wheelers to cars and buses. Graphite anodes are close to their limit; silicon is the next step.
How PoroSil™ helps
- Higher anode capacity for longer driving range without a bigger pack
- Designed for faster charge acceptance than graphite-only anodes
- Blends into existing cell lines — no new manufacturing process
Cellark-powered drone02Drones & Space
Longer flight time whereevery gram matters.
For drones, UAVs and space hardware, battery weight directly limits flight time and payload. Higher energy per kilogram means longer missions and more useful load.
How PoroSil™ helps
- More stored energy for the same battery weight
- Longer flight endurance and bigger payload headroom
- Indian-made anode material for strategic aerospace programmes
Every cell format03Consumer Electronics
More energy insideslimmer devices.
Phones, laptops, wearables and earbuds keep getting thinner while users expect longer battery life. The answer is more energy per cubic centimetre — exactly what silicon delivers.
How PoroSil™ helps
- Longer battery life in the same device footprint
- Works across pouch, coin and cylindrical cell formats
- Room for slimmer, lighter product designs
Cellark × IndianOil04Energy Storage
Denser storage for arenewable India.
Solar, telecom towers, homes and industry all need reliable backup and grid storage. Higher energy density means smaller, lighter systems that store more in the same space.
How PoroSil™ helps
- More kWh in a smaller footprint for solar and backup systems
- Supports a domestic supply chain for battery materials
- Developed with the support of leading partners like IndianOil
05Data Centers & Robotics
Compact backup power.Longer robot runtime.
Data centres need dense, dependable backup power, while warehouse robots and AMRs need to run full shifts between charges. Both are limited by how much energy their batteries hold.
How PoroSil™ helps
- Higher-density battery backup in less rack and floor space
- Longer operating time for robots and autonomous machines
- Faster charge acceptance for shorter downtime
06Defense
Mission-critical power,built in India.
Soldier-worn electronics, field communications, UAVs and remote sensors all depend on light, long-lasting batteries — and on a secure, domestic supply of the materials inside them.
How PoroSil™ helps
- Lighter, higher-energy power for portable and field systems
- Longer endurance for UAVs and remote equipment
- An indigenous anode material supporting Atmanirbhar Bharat
From material to market
From PoroSil™ powderto the products you use.
PoroSil™ is a drop-in anode material. Cell makers blend it with graphite in their existing process — and the gain carries all the way to the end product.
Porous silicon–carbon composite, made in our pilot plant.
Mixed with graphite using standard slurry and coating lines.
Pouch, cylindrical or prismatic cells with more capacity.
More range, runtime and endurance across every sector.
Illustrative model, not cell-test data — assumes 10 wt% PoroSil™ at 1,350 mAh/g with graphite at 350 mAh/g. *Rate capability is a Cellark laboratory result versus a graphite-only reference; full-cell validation required. Actual results depend on cell chemistry and design.
