Evonik developing the world's largest lithium ceramic battery

Mar. 6


In Germany, Evonik Industries and its partners are developing for this purpose the world's largest lithium ceramic battery. This has been made possible by CERIO® technology, a special combination of ceramic materials and highmolecular ionic conductors, which ensures greatly increased safety combined with a small footprint and long cycle lifetime.

As a first step, an energy storage device with an output of one megawatt (MW) and a storage capacity of about 700 kWh is being developed at the Völklingen power plant site in the Saarland. An example gives an idea of the performance of such a device: If it were charged and discharged every 15 minutes, the energy supplied would meet the needs of 4,000 households a year. Following the development of the 1-megawatt storage device, an expansion to 10 MW is planned.

“We're using our unique lithium ion expertise, which is already revolutionizing the electrification of the car, to enter an entirely new market,” says Dr. Klaus Engel, chairman of the Executive Board of Evonik Industries AG. “Using lithium ceramic technology, we've achieved, for the first time ever, cost effective decoupling of the generation and consumption of power. We can stabilize grid fluctuations arising from solar and wind power generation, and can therefore organize power generation with far greater overall efficiency. As in the automotive sector, this will be a billion-euro market,” predicts Engel. Experts estimate market volume for advanced energy storage devices at more than €10 billion in the long term.

Lithium ion batteries are currently being intensively developed worldwide for the drive systems of the future. This unique patented technology from Evonik is also at the core of our partnership with Daimler AG, which aims at mass producing electric vehicles from 2012 onward. In addition to the anode and cathode material, the SEPARION® ceramic membrane serving as a separator is at the core of the innovation.
