China’s battery industry is increasingly turning to sodium-ion technology as lithium prices rise and major manufacturers expand production and investment. Sodium-ion batteries are chemically similar to lithium-ion batteries but use more abundant raw materials. However, sodium-ion technology is being adopted more broadly, with several Chinese battery manufacturers investing in production capacity. BYD has commissioned a 30 GWh sodium-ion battery line, while EVE Energy has launched a 1 billion-yuan (about 144 million USD) sodium-ion project, and Ronbay Technology has converted part of its lithium battery production to sodium-ion materials. Industry observers suggest that 2026 could mark a period of accelerated commercialization for sodium-ion technology in China.
