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.

The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction. The new discovery shows that this neutral molten salt can undergo a further reaction into an acidic molten salt. of peak charge capacity. Weller et al.

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. But this particular salt, it happens, is very good at preventing that malfunction.

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.

The idea, says Daniel Codd , a researcher in renewable energy systems at the University of California, San Diego, is to store solar-produced heat in rock formations below the surface, creating a solar-charged geothermal resource in which heat is stored for meaningful durations. This can imply a long road to commercial success.”

Professor Donald Sadoway and colleagues have already started a company, Ambri (initially Liquid Metal Battery Corporation), to produce electrical-grid-scale liquid batteries, which comprise layers of molten material which automatically separate due to their differing densities. Earlier post.). —Wang et al. That was a stunner for us.

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.
