University of Sydney researchers have announced a new low-cost battery built with four times the capacity of lithium ion. The researchers are hoping that a new, low-cost battery is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonized economy. Led by Dr Shenlong Zhao from the University’s School of Chemical and Biomolecular Engineering, the battery has been made using sodium-sulfur – a type of molten salt that can be processed from sea water – costing much less to produce than…
