New molten salt battery could solve renewable energy storage problem
The EU-funded SOLSTICE project plans to develop two sodium-zinc molten salt batteries operating at high temperatures that could be used for stationary energy storage. The first battery will be based on ZEBRA technology, a type of rechargeable molten salt battery based on nickel, sodium and chloride. Instead of nickel, researchers will use cheap and abundant zinc as the positive electrode. In the second all-liquid battery, researchers will apply the same chemistry but will not use a ceramic electrolyte, thereby further driving down battery costs. Both battery concepts will be brought at a technology readiness level 5.
