High-performance batteries are key components in mobile and stationary electrically-powered applications, and are also the most complex elements in the system. Particularly in high energy and output ranges, the durability and reliability of a system must be high, placing significant technical demands on the batteries.

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

Electrical energy storage devices in vehicles must meet a particularly wide range of (sometimes contradictory) requirements, regarding for example their cost, energy and power density, cycle stability, temperature range and safety. In order to adapt lithium ion batteries for use in vehicles, optimization is needed in a variety of areas. The institutes of the Fraunhofer-Gesellschaft have competences in virtually all of these areas.
