Within the Horizon 2020 project SOLSTICE, sodium-zinc molten salt batteries are being developed. The first cell concept employs solid zinc powder embedded in molten salt electrolyte, together with a solid ceramic electrolyte – operating at 300°C, similarly to the commercially available ZEBRA batteries. Secondly, a high-temperature cell operating at 600°C with fully liquid electrodes and electrolyte is being investigated.
The talk will give an overview of the current state of research on high-temperature Na-Zn batteries, including electrochemistry, molten salt chemistry, salt corrosion, cost aspects, cell design and risk assessment.
