The world's largest sodium-ion battery is launched: how powerful it is

The world's largest sodium-ion battery has been put into operation in Qianjiang, Hubei Province (China). State-owned power company Datang Group connected it to the grid at the end of June.

The energy storage was built using sodium-ion batteries with a capacity of 185 Ah, manufactured by HiNa Battery. The system consists of 42 battery containers and 21 sets of boost converters. HiNa batteries broke their own record, which they had held since May of this year, when a 10MW facility went live in Nanning.

The sodium-ion battery system in Qianjiang will store up to 100,000 kWh of electricity per charge and will distribute it to 12,000 households for everyday needs. On this scale, the installation will help to avoid equivalent emissions of carbon dioxide of 13,000 tons per year.

In the future, the capacity of the Nanning facility is expected to increase to 100 MWh, and in the next phase, the capacity of the Qianjiang facility will increase to 200 MWh.

What advantage of such batteries

Sodium-ion batteries have advantages over lithium-ion batteries. They are made from sodium, which is widely available and easier to mine than lithium. In addition, due to the increase in demand, lithium prices are at a record high level, making it difficult to switch to environmentally friendly energy sources. But an alternative made of widely available and cheap materials makes the transition easier.

Also, sodium-ion batteries have the best safety performance, they work well at extremely low and high temperatures, able to guarantee 85 percent charging and discharging efficiency at temperatures – 20 degrees Celsius, which has no equal among other batteries. Such batteries can withstand 1,500 charge-discharge cycles at high temperatures — +60 degrees Celsius.
