HomeAbout Us
Cellark Powertech is an advanced battery-materials company rooted in a decade of research at IIT Bhubaneswar — building India’s own supply of silicon–carbon anode materials.
Our story
Cellark Powertech Pvt. Ltd. was founded in 2018 to take a decade of porous-silicon research at IIT Bhubaneswar out of the laboratory and into real-world lithium-ion cells.
Today, our multidisciplinary team combines materials science, battery engineering and industrial production experience to scale PoroSil™ — our silicon–carbon anode material — from pilot-scale sampling towards commercial production, made in India for the world’s cell makers.
Vision & Mission
Our journey
A decade of clean-energy materials research lays the scientific foundation for porous silicon anodes.
The company is formed to commercialise silicon–carbon anode technology for lithium-ion batteries.
PoroSil™ is registered with the Trade Marks Registry, Government of India (TM No. 5461095, Class 1).
Our innovation portfolio grows to five patents — two granted and three applications filed.
Our Li-ion battery Si anode production pilot plant begins producing PoroSil™ material in-house.
Samples and joint-development programmes are open for cell manufacturers, battery developers and strategic partners.

Co-Founder & CEOMechanical engineering graduate with a master’s in materials engineering from IIT Bhubaneswar. He brings seven years of energy-sector experience and a deep understanding of India’s clean-energy business ecosystem.
Co-FounderA clean-energy materials researcher with more than 15 years of R&D experience. He is an Associate Professor at IIT Bhubaneswar.
Senior Research EngineerPhD from IIT Bhubaneswar (2022) with expertise in powder metallurgy, powder synthesis, lithium-ion electrode manufacturing and fabrication.
Advisor · Production & Scale-upA chemist with 28 years of experience in industrial research, technology development and management, including roles at CSIR-IMMT and Gharda Chemicals.
Years of combined experience across clean energy, advanced materials and industrial R&D — spanning powder synthesis, battery electrode manufacturing and industrial process development. This technical depth, paired with knowledge of India’s clean-energy market, positions us to scale silicon–carbon anodes from lab to commercial production.
What drives us
Four values guide how we research, build and partner — from the lab bench to the production floor.
Every product decision is grounded in rigorous materials research and real test data.
Building a domestic supply chain for critical battery materials — for India and the world.
Processes designed from day one for industrial manufacturing, not just the laboratory.
We co-develop with cell makers, institutions and industry to get materials into real cells.
Where we work
Our registered office sits inside the Research & Entrepreneurship Park at IIT Bhubaneswar, close to the labs where our technology was born — with pilot production operations in Odisha.
Room No. 20, CRIF Building, Research & Entrepreneurship Park, IIT Bhubaneswar, Argul, Jatni, Khordha, Odisha 752050
