【Sodium batteries: China's first 10MWh sodium-ion battery energy storage station has been officially put into operation in Nanning, Guangxi】 On May 11th, China's first 10MWh sodium-ion battery energy storage station was officially put into operation in Nanning, Guangxi. Guangxi Fulin Sodium-ion Battery Energy Storage Station is the first time that sodium-ion battery energy storage has achieved large-scale application in China. At present, the energy conversion efficiency of this sodium-ion battery energy storage system can exceed 92%, which is higher than that of the commonly used lithium-ion battery energy storage system.
