Messe Düsseldorf (IKTS) has developed a low-cost, ceramic high-temperature battery for stationary storage. The principle of the technology has been known since the 1990s and it has now become possible to adapt the technology for applications to PV home storage. The 130 kWh Cerenergy battery relies on a combination of sodium nickel chloride, eliminating the need for costly rare earth minerals, and has a cellular cost of € 100 /kWh – half that of lithium-ion batteries. IKTS said the module achieved a 50% efficiency with an energy density of 5 W/kg , and would be ready for production in the 1990s .
