VALUE.
Flash chemistry. Advanced membranes. Precision electrolysis. Magnetic separation. Printed photovoltaics. Self-reinforcing technology loops across energy, materials, and mining.
// 01 · Verticals
FOUR PILLARS.
ONE SYSTEM.
Each vertical feeds the others. Outputs from one process become inputs for the next, building a self-reinforcing loop that compounds in value with every unlock.
01 ————
Energy Storage
Iron-based all-flow redox batteries using in-house proton-exchange membranes and ferric chloride electrolyte. No scarce metals. Arbitrage-ready grid-edge storage.
02 ————
Advanced Chemistry
Flash Joule synthesis of turbostratic graphene, nano-iron, and nanodiamond. Chlor-alkali electrolysis producing NaOH, HCl, Cl₂, and H₂ from local salt inputs.
03 ————
Mining & Refining
Prospecting across Sri Lanka's gold, rare-earth, and mineral-sand belts. Gravity and magnetic separation feeding on-site refinery for precious metals and oxide production.
04 ————
Renewables
Roll-to-roll printed perovskite solar cells using locally-derived TiO₂ pigment. Thermophotovoltaic research and integrated solar farm development for grid supply and arbitrage.

THE UNLOCK
CHAIN.
Each technology unlock cascades into the next. Electrolysis outputs become battery electrolytes and refining reagents. Flash-synthesised graphene upgrades batteries, tyres, and concrete. Mining outputs feed the solar pigment pipeline. No unlock is an island.
UNLOCK 01
Electrolysis
MMO-electrode brine cells producing NaOH, HCl, Cl₂, and H₂ — the chemical backbone of every downstream process.
▶UNLOCK 02
Membranes
Sulfonated polyethylene cation-exchange films enabling zero-gap cells and iron flow batteries.
▶UNLOCK 03
Flash Joule
Millisecond joule-flash synthesis of turbostratic graphene, nano-iron, and nanodiamond from local carbon feedstocks.
▶UNLOCK 04
Gravity & Mag Sep
Shaking tables and drum separators concentrating gold, rutile, monazite, and iron ore from alluvial deposits.
▶UNLOCK 05
Redox Battery
All-iron flow battery stacks using in-house membranes and FeCl₃ electrolyte — scalable and repairable.
▶UNLOCK 06
Printed Solar
Roll-to-roll perovskite cells using TiO₂ from local rutile. Solar farm integration closes the cash loop.
SYNERGY NOTE — Outputs from Unlock 01 (NaOH/HCl) feed directly into Unlock 05 electrolyte chemistry. Unlock 03 graphene enhances Unlock 05 electrodes. Unlock 04 rutile pigment feeds Unlock 06 perovskite cells.

WE BUILD
THE LOOPS.
Work With Us →
Cenfracee is a Sri Lanka-based resource technology company building self-reinforcing production loops across energy storage, advanced materials, mineral recovery, and renewable photovoltaics.
Our philosophy is that real value creation comes from owning the full chain — from raw mineral to finished energy product — and from technologies that feed each other. Every unlock we achieve compounds the value of all the others.
We are building in Sri Lanka, for Sri Lanka first, with technology that can scale globally.
