Evonik developing the world’s largest Li-ceramic battery

By Gerald Ondrey |

Evonik Industries AG (Essen, Germany; www.evonik.com) and its partners are developing the world’s largest lithium ceramic battery. This has been made possible by CERIO technology, a special combination of ceramic materials and high-molecular 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-MW 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 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…
