Sustainable High-Energy Supercapacitors Replacing Critical Raw Material Batteries

energyPilotedTRL 6

Imagine a battery that charges as fast as a flash and lasts much longer, but without using rare or toxic minerals. This project uses ultra-thin carbon sheets and special salts to store more energy than typical capacitors. It's like giving a sprinter the endurance of a marathon runner while keeping the equipment eco-friendly.

The business problem

What needed solving

Current energy storage relies on Critical Raw Materials (CRMs) that are hard to source and environmentally damaging. Existing supercapacitors also lack the energy density required to replace batteries in high-end applications.

The solution

What was built

Cylindrical prototype cells and pouch cell demonstrators. A supercapacitor management system for high-end application integration.

Who can put this to work

Electric Mobility
enterprise
Target: EV Manufacturer

If you are an EV manufacturer dealing with battery degradation and rare mineral shortages — this project developed CRM-free supercapacitors that provide energy densities >20 Wh/kg. This allows for faster charging and longer cycle life without relying on critical raw materials.

Industrial Automation
mid-size
Target: Heavy Machinery OEM

If you are a machinery OEM dealing with equipment failure in extreme temperatures — this project developed a system that operates from -50°C to +100 °C. This eliminates the need for expensive and heavy cooling systems in your hardware.

Renewable Energy
any
Target: Grid Storage Provider

If you are a storage provider dealing with the environmental impact of lithium battery disposal — this project developed recyclable ionic liquid electrolytes. This ensures your energy storage infrastructure aligns with circular economy requirements.
