State of Safety: Research for safe lithium batteries

Electrical energy storage systems (EES), which are currently based primarily on lithium-ion technology, are a key to e-mobility as well as to the energy transition. They make it possible to reduce CO2 emissions in transport and to temporarily store renewable energy from wind and sun.

The focus at BAM is on the state of safety of electrical energy storage systems. This concerns all processes related to the charging, use and recycling of large and small batteries.

A holistic view of the state of safety is also indispensable in the development of innovative storage materials and battery components. For this purpose, BAM has unique state-of-the-art testing and experimental facilities - from laboratory to real scale.

The State of Safety also comes into play when prototypes of new storage units have to be transported or defective lithium batteries have to be recycled and disposed of. As the higher federal authority, BAM has the sovereign task of approving the corresponding packaging and specifies the conditions for transport. To this end, we are involved in rule-making and standardisation at European and UN level.

With its comprehensive expertise on the state of safety of electrical energy storage systems, BAM is an ideal partner for science and industry in research on current and future battery technologies.
