AU Researchers Develop Cheap Salt Battery

Researchers at Murdoch University in Perth, Western Australia are developing water-based sodium-ion battery.

Dr. Minakshi says a water-based sodium-ion battery he and Dr Danielle Meyrick are developing has shown excellent potential for affordable, low-temperature storage.

The concept of using salts for energy storage is nothing new, with molten salt batteries already rolled out in a number of solar farms; including the world’s first baseload solar generation facility in Spain.

“To provide power at non-generation times, excess energy needs to be stored in batteries, but storage technologies now being considered, such as molten salt or molten sulfur, work at high temperatures, making them expensive and impractical” says Dr Manickam Minakshi  of Murdoch’s School of Chemical and Mathematical Sciences.

“While the technology is too bulky for portable devices, it has excellent potential for large-scale use, including storing energy from wind turbines and solar farms for later feeding into local electricity grids, as well as use in industry.”
