The iron salt battery, as developed by Voltstorage, addresses the growing need for long-term battery storage to support renewable energies. As an alternative solution to lithium-ion batteries, it offers a sustainable, cost-effective, and safe solution for long-term storage of wind or solar energy. The international development of the technology is progressing, and the current status was presented at events such as the International Flow Battery Forum (IFBF) in Glasgow and the ees Forum in Munich.
The Munich-based startup Voltstorage is working with the technology and advancing further patent applications. The company has now begun the next development phase, which includes a twentyfold increase in performance. Additionally, the implementation of fully automated test systems, an enhanced battery health management system, a defined form factor concept, and a higher technology readiness level (TRL) are part of the newly launched development stage.
Jakob Bitner, co-founder and CEO of Voltstorage, explains:
“We are already in discussions with potential partners to define solution concepts tailored to their specific needs. This includes energy suppliers and large industrial companies looking for cost-effective, sustainable, and safe LDES solutions that will enable them to improve the production and use of renewable energy.”
Voltstorage remains on schedule with development
As part of the next development stage now underway, Voltstorage is distributing its development work across multiple parallel objects. In this way, the startup aims to increase the volume of collected test data. One of these objects – Voltstorage refers to development stands – focuses on operation with multiple battery cells. Another is equipped with a cell enlarged threefold. The development stands are operated at Voltstorage’s location in Munich, which enables close collaboration between the research and development and product development teams.
Verena Graf, CTO of Voltstorage, says:
“The hard work and high expertise of our experts are crucial to our success. We are confident that we will remain on schedule in the development of our iron salt battery and through continuous progress will ultimately create a reliable and efficient LDES solution for the renewable energy market.”
