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.

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.

Tests conducted by Titirici Group , a multidisciplinary research team based at Imperial College London, have found that a novel carbon nanotube electrode material derived from CO 2 —produced by Estonian nanotech company UP Catalyst ( earlier post )—enhances the cyclability of sodium-ion batteries.

The PNNL researchers have developed a process to grow high-performance crystals in molten salts—sodium chloride, common table salt—at high temperature. The gliding occurs as the battery charges and discharges—lithium ions depart and return to cathode, straining the crystal ever so slightly each time.

Others solid battery types are nickel-cadmium and sodium-sulphur, while zinc-air is emerging. Technologies include energy storage with molten salt and liquid air or cryogenic storage. Batteries encompass a range of chemistries. SETEC POWER is keenly aware of market demand and industry changes.

Furthermore, the lithium insertion and extraction reactions that take place during charge and discharge, respectively, occur with no significant contraction/expansion of the crystal lattice, resulting in a much higher cycle life. Hydro-Québec invests more than $100 million per year in research.

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.
