Core Viewpoint - The first large-capacity sodium-ion battery energy storage station in China has officially commenced its expansion project, enhancing the capacity for efficient consumption of renewable energy [1][3]. Group 1 - The newly expanded energy storage station in Wuming District, Nanning, Guangxi, is part of a national key research and development project focused on "hundred-megawatt-hour sodium-ion battery storage technology" [1]. - The station can achieve an annual charge and discharge cycle of up to 600 times, which will allow for the consumption of approximately 30 million kilowatt-hours of wind and solar energy each year [3]. - This energy consumption is equivalent to reducing standard coal consumption by 9,000 tons and cutting carbon dioxide emissions by 13,500 tons, which can meet the annual electricity needs of about 20,000 households [3].
