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.

As the pressure to decarbonize electricity grids mounts, so does the need to have long-term storage options for power generated from renewables. Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries.

We are transitioning from fossil fuels to renewable energy sources such as wind and solar, and the use of energy storage is becoming more widespread. 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.

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.

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. A number of licences have recently been granted for patents within the IP pooled portfolio.
