Your electronics could soon be powered by an ultra cheap sea salt battery.
Researchers have built a new cheap battery with four times the energy storage capacity of lithium.
Constructed from sodium-sulphur - a type of molten salt that can be processed from sea water - the battery is low-cost and more environmentally friendly than existing options.
It could be a ‘breakthrough’ for renewable energy, according to lead researcher Dr Shenlong Zhao, from the University of Sydney.
