According to Chinese media reports, the cost of sodium-ion cells starts at 500 CNY ($77) per kWh at a small scale, and can be halved to 200-300 CNY ($31-$47) per kWh at a volume scale, making them potentially very competitive.
Energy-Storage.news has been told anecdotally that one reason China is investing so heavily on sodium-ion technology is because of fears that, long-term, it could start to be cut out of the lithium supply chain.
Sodium-ion batteries, developed with China’s proprietary technology, offer higher thermal adaptability and greater raw material security. Their maximum output and response speed are reportedly three and six times greater, respectively, than traditional sodium-ion batteries.
As standardization frameworks develop, lithium-sodium hybrid systems could see broader deployment across China’s renewable-rich regions such as Tibet, Xinjiang, and Gansu. Grid-forming storage is projected to account for up to 40% of China’s new energy storage market by 2030.
Lithium batteries, known for their maturity and fast response, handle high-frequency grid regulations. Sodium-ion batteries, developed with China’s proprietary technology, offer higher thermal adaptability and greater raw material security.
Sodium-ion has a lower energy density and, because of lower scale, generally a higher cost than lithium-ion, although by 2025 it could already be 15-30% cheaper than lithium-ion according to BYD. However, commercialisation and cost reductions have come slower than expected, Yicai Global said.
