Battery Alliance

High-performance batteries are essential components in both mobile and stationary electric-powered applications, and they are also the most complex parts of these systems. Especially in high energy and power ranges, the durability and reliability of the system must be exceptional, placing considerable technical demands on the batteries.

The Battery Alliance focuses on both primary and secondary (rechargeable) systems, ranging from small-scale applications like button cells to large stationary systems such as redox-flow batteries.

Electrical energy storage devices in vehicles must fulfill a broad set of often conflicting requirements, such as cost, energy and power density, cycle stability, temperature range, and safety. To optimize lithium-ion batteries for vehicle use, improvements are necessary in several areas. The Fraunhofer-Gesellschaft institutes possess expertise in nearly all of these fields.

The Fraunhofer Battery Alliance is a collaborative initiative involving 26 Fraunhofer institutes that focuses on advancing research in electrochemical energy storage devices, such as batteries and super-capacitors. Its goal is to develop both technical and conceptual solutions for the commercial application of these technologies. The alliance prioritizes the social, economic, and ecological implications of energy storage technologies, ensuring that their development is aligned with sustainable practices.

As part of its mission, the Battery Alliance will continue to expand and enhance research in the field of electrochemical energy storage, positioning it as a key business area within the Fraunhofer-Gesellschaft. The alliance’s expertise spans a wide range of areas, including materials science, cell production, energy storage systems, simulation, and testing. These efforts aim to support the development of more efficient, sustainable, and economically viable energy storage solutions for various industries.
