China's first sodium ion battery could cut reliance on lithium
The success of the station could have big implications for the industry, as the new technology is seen as a promising alternative to resource-dependent lithium batteries.
The station in Nanning, in the Guangxi autonomous region in southern China, has a storage capacity of 10 megawatt hours The success of the emerging battery technology could cut reliance on imports of raw materials such as lithium and cobalt Once sodium-ion battery energy storage enters the stage of large-scale development, its cost can be reduced by 20 to 30 per cent, said Chen Man, a senior engineer at China Southern Power Grid. This can be achieved through further improvements in the sodium-ion battery structure, manufacturing process, material utilisation and cycle life, thus lowering the energy storage cost per kilowatt-hour of electricity, he said.
