China’s first large-scale sodium-ion battery fees to 90% in 12 minutes

China’s first main sodium-ion battery power storage station is now on-line, based on state-owned utility China Southern Energy Grid Vitality Storage.

The Fulin Sodium-ion Battery Vitality Storage Station entered operation on Could 11 in Nanning, the capital of the Guangxi Zhuang autonomous area in southern China. Its preliminary storage capability is claimed to be 10 megawatt hours (MWh). As soon as absolutely developed, the Station is anticipated to succeed in a complete capability of 100 MWh.

The state utility says the ten MWh sodium-ion battery power storage station makes use of 210 Ah sodium-ion battery cells that cost to 90% in a mindblowing 12 minutes. The system contains 22,000 cells.

As soon as the undertaking reaches 100 MWh, it may launch 73,000 MWh of fresh power annually. That’s sufficient to energy 35,000 households and scale back carbon dioxide emissions by 50,000 tonnes yearly.

In an interview with China Central Tv, Gao Like, a supervisor on the Guangxi department of China Southern Energy Grid, mentioned that the power conversion effectivity of its sodium-ion battery power storage system exceeds 92%. It’s similar to the effectivity of widespread lithium-ion battery storage programs, at 85-95%.

Chen Man, a senior engineer at China Southern Energy Grid, mentioned [via the South China Morning Post] that after sodium-ion battery power storage enters the stage of large-scale improvement, its value will be decreased by 20-30%. He continued:

This may be achieved by additional enhancements within the sodium-ion battery construction, manufacturing course of, materials utilization, and cycle life, thus reducing the power storage value per kilowatt-hour of electrical energy.

Massive-scale sodium-ion batteries are gaining momentum because of their decrease value and abundance of uncooked supplies in comparison with lithium-ion batteries. The challenges with sodium-ion batteries have been decrease power density and shorter lifespans that may restrict effectivity and long-term efficiency in large-scale functions.
