Eco-friendly Supercapacitors with Battery-like Energy Density for Flexible and Structural Electronics

energyTestedTRL 4

Imagine a battery that charges instantly and lasts forever, but is as thin as a sticker or built directly into the frame of a drone. Instead of using heavy metals, this tech uses charred pistachio shells and wood to store power. It's like turning a structural part of a machine into its own fuel tank.

The business problem

What needed solving

Current energy storage struggles to balance high power output with high energy density while remaining environmentally sustainable. Batteries are energy-dense but slow to charge and often toxic, while supercapacitors are fast but lack the capacity for long-term use.

The solution

What was built

Bio-based carbon electrodes and ALD-coated graphene electrodes. Two demonstrators: a wireless sensor with a flexible supercapacitor and a drone with structural supercapacitors.

Who can put this to work

Aerospace & Robotics
SME
Target: Drone manufacturer

If you are a drone manufacturer dealing with heavy battery packs that reduce flight time — this project developed structural supercapacitors that serve as integral components of the drone. This allows the frame itself to store energy, potentially increasing efficiency and payload capacity.

IoT & Wearables
any
Target: Wireless sensor developer

If you are a sensor developer dealing with rigid batteries that don't fit curved surfaces — this project developed a printed flexible supercapacitor. This enables the creation of wireless sensor devices that are thin, bendable, and eco-friendly.

Green Manufacturing
mid-size
Target: Energy storage component producer

If you are a component producer dealing with the environmental impact of traditional capacitors — this project developed bio-based carbon materials from pistachio shells and alder wood. This provides a sustainable path to reach energy densities > 50 Wh/kg.

Frequently asked

Quick answers
