Cancrie

Cancrie is a Jaipur, India-based advanced materials company that converts lignocellulosic agricultural and industrial residues, including coconut shells, into engineered nanocarbon powders used as additives in batteries and capacitors. The materials are positioned as a drop-in alternative to petroleum-based carbons, intended to integrate into existing battery manufacturing lines without process changes or added cost per cell. The company states its technology is patent-granted and built on more than 13 years of research, with a library of over 250 nanocarbon formulations and validation across more than 20 biomass feedstocks.

The company describes its materials as chemistry-agnostic, supporting lead-acid, lithium-ion, sodium-ion, redox flow batteries and supercapacitors. Claimed performance effects include up to 60% higher charge acceptance, roughly 20-25% higher energy density, around 25-30% longer cycle life for lead-acid batteries, four times stronger electrodes, lower internal resistance and up to 14% higher active material utilisation. Target applications span automotive batteries, solar storage, drones, e-rickshaws and UPS systems. Cancrie also frames its process as environmentally advantaged, citing 89% lower energy consumption, 20x lower greenhouse gas emissions and circular manufacturing with chemical and heat recovery and zero discharge, and estimates a reduction of 0.25 kg of CO2 per battery using its material.

Cancrie reports that its material has been tested at ARAI, NABL and other third-party accredited laboratories and proven at industrial scale with more than 20 battery manufacturers.
