QT-Batt

Overview

QT-Batt is a Helmholtz research project on quantum technologies for battery development and diagnostics. The project aims to use quantum computing and quantum sensing to gain new insights into electrochemical processes and to accelerate the development of next-generation battery technologies.

The central idea is that quantum technologies can serve as innovation accelerators in battery research. Quantum-computing approaches are used to investigate battery materials and electrochemical processes across different levels of description, while quantum sensors are explored as tools for monitoring batteries during operation and for obtaining high-resolution insight into processes at the atomic scale.

Research Focus

QT-Batt targets two complementary directions:

• quantum simulations of battery materials and electrochemical processes to support model-based materials discovery, and
• quantum-sensor approaches for in operando battery diagnostics with atomic-scale sensitivity.

These approaches are intended to complement and partially replace traditional trial-and-error strategies in battery development, with the broader goal of improving performance, reliability, and technological sovereignty in energy storage.

Consortium and Contribution

QT-Batt is funded by the Helmholtz Association as part of the Quantum Use Challenge and runs from 2026 to 2028. The project involves several Helmholtz Centres, including:

• Forschungszentrum Jülich
• Helmholtz-Zentrum Dresden-Rossendorf (HZDR)
• Helmholtz-Zentrum Berlin for Materials and Energy (HZB)
• GSI Helmholtz Centre for Heavy Ion Research

Within QT-Batt, our group contributes to the scientific development of quantum-computing approaches relevant to battery research.
