Circunomics lab for battery testing is open
Verifying results of AI-based battery analyses with real-life simulation
Efficiency and accuracy of analyses further enhanced
Precise predictions for 2nd-life battery usage
Mainz/Roßdorf. 28 May, 2025. Circunomics, headquartered in Mainz, has officially opened their own lab in Roßdorf, near Darmstadt, and has commenced full operations. The goal of the new battery lab is to compare, train, and verify analyses of used battery cells conducted with AI-supported software against laboratory values obtained from real-life simulation. This enables Circunomics to build a data foundation for it’s exclusive software which determines the state of health of a used battery with added precision, during and after its first life. More importantly, they will now be able to simulate and project in detail how a battery will behave in its second life, such as in a stationary storage system. Additionally, Circunomics will be able to make recommendations as to which batteries are best suited for specific projects.
Circunomics is using its new battery lab to continue its expansion. These strides are made possible by a successful completion of their Series A financing round. At the beginning of 2025, Circunomics received over eight million euros from investors.
Various cells can be housed simultaneously at the lab in Roßdorf. The cells are securely shielded in a the testing facility and subjected to a wide range of stresses, depending on the requirements and programs. Extensive real-life simulations of dily battery usage scenarios can be performed. One example of this is in an e-vehicle – rapid or slow successive charging cycles, varying charging voltage of up to 300 amps DC, various states of battery degradation, and all of this at different temperatures. A temperature range from -20 to 60 degrees Celsius is possible. These cell test can be conducted over short, medium, or long periods of time, raging from a few days, weeks, months, or up to two years.
“Until now, we had our cells analyzed by an external service provider. We are now moving this task in-house which increases our efficiency and speeds up our data comparision. This enables us to offer our simulations and projections for second-life use with more accuracy and reliability.” Explains Jan Born, Co-Founder and CTO of Circunomics. He adds, “On the one hand, we have millions of data points collected made available to us during the first-life of a battery. Based on this, we have now used our AI supported software to analyze what the used battery is still capable of in its second-life before it is recycled. Through our own lab analyses, we can now see how a cell behaves in a simulated battery life. We can compare and verify the results obtained with those from the software.”
Depending on the workload, up to six software and battery specialists work in the Circunomics lab. The entire facility is secured by an infrastructure that even under full and continuous capacity, various analyses can be carried out in parallel with sufficient and reliable power supply. The testing facility features multiple safety measures, including a CO2 extinguishing system and round-th-clock monitoring via data trasfer and camera recordings.
With its intelligent and unique battery lifecycle management solution, consisting of a digital marketplace for the battery trade and integrated analytics, Circunomics, GmbH, founded in 2019, has made a name for itself within the circular economy. Wit its global offering, the company enables batteries, modules, and cells to be integrated into a sustainable and comprehensive lifecycle. It connect industry partners involved at all stages of the battery supply chain. In turn, this helps to reduce the carbon footprint for the benefit of the environment and the use of valuable and rare materials. Additionally, this results in an optimized usage of the value chain.
