Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction. Weller et al.

Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries. A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required.

Nickel offers relatively low cost, wide availability and low toxicity compared to other key battery materials, such as cobalt. The PNNL researchers have developed a process to grow high-performance crystals in molten salts—sodium chloride, common table salt—at high temperature.

MIT professor Donald Sadoway and his team have demonstrated a long-cycle-life calcium-metal-based liquid-metal rechargeable battery for grid-scale energy storage, overcoming the problems that have precluded the use of the element: its high melting temperature, high reactivity and unfavorably high solubility in molten salts.
