Chinese automaker BYD has built the world’s first mass-production facility for sodium-ion batteries in Chongqing. The factory has a planned annual capacity of 20GWh and will start producing batteries in 2025.

BYD’s sodium-ion batteries will use a new battery chemistry developed in-house. The company claims its batteries have a range comparable to lithium-ion batteries but with advantages such as faster charging times and higher energy density.

The new factory represents a major investment by BYD in sodium-ion technology. The company sees great potential for sodium-ion batteries due to the abundance and lower cost of sodium compared to lithium.

BYD plans to initially use the sodium-ion batteries produced at this factory in its electric buses. Over time, the company may expand the use of sodium-ion batteries into its electric cars and other applications.

The opening of this large-scale sodium-ion battery factory highlights China’s ambitions to lead in next-generation battery technologies. With strong government support, Chinese companies like BYD aim to leapfrog established lithium-ion batteries.

As you can see, the Chinese batteries have taken a step that we would not have liked to see, given the relevance it will have for our industry. The problem? It is not a shared innovation, but an invention that remains hidden from the rest of the world. There is still a long way to go to see if they decide to extend them to the rest of the planet and replace lithium forever.
