An international team of researchers are hoping that a new, low-cost battery which holds 4X the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonised economy.
Led by Dr Shenlong Zhao from the University’s School of Chemical and Biomolecular Engineering, the battery has been made using sodium-sulphur — a type of molten salt that can be processed from seawater — costing much less to produce than lithium-ion.
Although sodium-sulphur (Na-S) batteries have existed for more than half a century, they have been an inferior alternative and their widespread use has been limited by low energy capacity and short life...
