Zero-NMP Clean Process
Establishing a localized, secure, and sustainable supply chain for advanced supercapacitor cells and raw carbons.
Our upgrading and electrode processes are legally licensed from CSIR-CECRI, Karaikudi. Developed by Dr. M. Sathish, Senior Principal Scientist.
Tamil Nadu represents one of the largest coconut belts in India. Raw shell feedstock provides an direct source for supercap-grade carbons.
We use a water-based binder process that eliminates toxic NMP solvents, ensuring RoHS compliance, lower manufacturing costs, and environment safety.
As standard sources tighten, Igonix Carbons operates out of Coimbatore, adjacent to Chennai and Cochin ports, facilitating bulk exports worldwide.
We control the manufacturing cycle, ensuring strict quality checkpoints at each critical upgrade stage.
We source clean, dry coconut shells directly from farm cooperatives across Tamil Nadu. High density and low ash precursor properties make coconut shells the optimal organic framework for high-energy density activated carbon.
Pyrolysis is performed in rotary kilns under strict thermal profiles, excluding oxygen. This process converts the raw biomass into pure charcoal by driving off volatile compounds, initiating the internal honeycomb structure.
Our activation chambers expose the charcoal to water vapor or CO2 at high temperatures. This carves out billions of microscopic crevices, expanding the internal surface area to the target 1,500–2,000 m²/g range, crucial for EDLC electrostatic energy storage.
The raw activated carbon undergoes chemical purification licensed from CSIR-CECRI. High-purity acid leaching washes away inorganic ash and trace minerals, reducing internal leakage current and increasing electrochemical stability.
We prepare the electrode coating using a water-based binder system. This eliminates toxic NMP solvents, creating a sustainable, green process. The homogeneous slurry is continuously coated onto current collector foils with micron-level precision.
Coated electrodes are cut into specific ribbons, layered with separators, and tightly wound into cylinders. Aluminum tabs are ultrasonic-welded, and cells are placed inside protective aluminum canisters, ready for organic electrolyte filling.
Every single cell undergoes structural vacuum drying and electrochemical aging cycles. Internal leakage currents, ESR at 1 kHz, and capacitance are measured and recorded. Data sheets are compiled for batch transparency.
Custom packaging ensures moisture-proof and anti-static containment. We ship directly from Coimbatore via Tuticorin, Chennai, or Cochin sea ports. Samples are couriered globally for engineering evaluation.
Our advanced carbon purification processes are licensed under formal agreement from the Central Electrochemical Research Institute (CSIR-CECRI), Karaikudi. Developed by scientists in carbon nanotechnology, this chemistry ensures domestic capability, shielding OEMs from geopolitical supply chain delays.

Traditional EDLC electrode casting uses PVDF binders dissolved in N-Methyl-2-pyrrolidone (NMP), a toxic organic solvent under stringent EU/US environmental regulations.
Our Process A licensed water-based binder uses deionized water, which reduces processing hazards, eliminates solvent recovery plant costs, and delivers a clean carbon interface compatible with global ROHS standards.
