Sodium batteries in all their variants are promising alternatives to the lithium cells currently in use. This is reflected in the increasing interest shown by experts and the public. At the invitation of the Fraunhofer Institute Dresden, numerous representatives from science and companies took part in the 4th “International Sodium Battery Symposium” on September 4 and 5, 2023. Alumina Systems presented the prototype of the CeraSalt® Na/NiCl2 battery for home use at the symposium.
Alumina Systems Managing Director Dr. Holger Wampers and Karl-Hermann Buchner (Development of the Battery Systems division) presented the first prototype of the CeraSalt® Home Solutions to the numerous experts. CeraSalt® battery storage system based on Na/NiCl2. In his presentation, Dr. Wampers pointed out the many advantages of CeraSalt® batteries. “The raw materials for this battery come from Europe, neither lithium nor cobalt are required. The batteries can therefore also be 100 percent downcycled,” Dr. Wampers emphasized. Due to their intrinsic safety (non-flammable, non-explosive), CeraSalt® batteries can also be installed anywhere in buildings without additional structural measures (such as fire protection, ventilation), whether in basements, garages or attics. Dr. Wampers also pointed out that the CeraSalt® batteries do not require any maintenance over their service life of at least 15 years. “Our CeraSalt® batteries also work in extreme temperatures, from -20 to +60 degrees Celsius,” Dr. Wampers emphasized.
Market launch schedule:
The CeraSalt® Na/NiCl2 battery is suitable for all stationary applications, e.g.
CeraSalt® Home: as a home storage solution for photovoltaic systems in single-family or multi-family homes. Market launch planned for the end of Q1/2024.
CeraSalt® Pro: as a modular rack installation and as large storage units in shipping containers for storage, peak shifting and peak storage in wind farms and solar fields. Market launch planned for the end of Q2/2024.
CeraSalt® UPS: as an uninterruptible power supply, e.g. in telecommunications, hospitals and critical infrastructure (e.g. public administrations, emergency control centers, municipal utilities, etc.). The market launch is planned for the end of 2024.
