Bio mass-derived Microsupercapacitors for IoT devices

Introduction

The increasing importance of the Internet of Things (IoT) for applications within e.g. climate monitoring for agriculture, water quality measurements, or industrial process control drives the development of compact microelectronic systems for portable wireless sensors. In consequence, the demand for miniaturised energy storage systems is growing rapidly.

Research Overview

In our ERC-funded research, we have invented a novel method for the fabrication of biomass-derived 3D electrodes for electrochemical energy storage with custom-made dimensions and shape.

Project Objective

Within BioMiCap, our objective is to transition from laboratory-scale single electrode studies with aqueous electrolytes into a commercially relevant encapsulated microsupercapacitor (µSC) device with thermally stable electrolytes.

Key Features

Compared to existing µSC, our electrodes have the following advantages:

• Binder-free
• Without metal current collector
• Recyclable

The use of additive manufacturing technology allows for the fabrication of custom-made miniaturized energy storage devices for specific IoT applications.

Validation and Commercialization

We will validate the biomass-derived µSC as a sustainable and green power source for IoT devices through field tests in collaboration with our industrial partners.

Innovation Process

The innovation process includes:

1. An analysis of commercial feasibility
2. A follow-up on the existing IP strategy
3. The development of a business strategy that enables the commercial exploitation of the µSC by a spin-off company.
