Fraunhofer develops ceramic high-temperature battery
The Fraunhofer IKTS has picked up the principle of the sodium-nickel chloride battery developed in the 90s and brought this to series production. The storage systems are in particular suitable for photovoltaic systems.17 Feb. 2019 Roland Freist
The Fraunhofer Institute for Ceramic Technologies and Systems IKTS plans to showcase its high-temperature battery cerenergy – and specifically the 5 kWh, 20 battery cell model – at Energy Storage Europe 2019 in Düsseldorf in mid-March. The sodium-nickel chloride battery is primarily based on sodium chloride, one of the most cost-efficient raw materials in the world. No rare earths or other strategic resources are used. In addition to sodium chloride, only a ceramic Na ion-conducting electrolyte made of doped aluminum oxide, as well as nickel and iron are required.
Together they create an energy storage system with an overall efficiency of > 90% and an energy density of 130 watt hours per kilogram. The operating temperature, which easily reaches 300 °C for ceramic battery solutions, is shielded from outside influences by a vacuum insulation.
