At the close of 2025, the continued rise in lithium carbonate prices pushed up lithium battery costs. With expectations of future cost advantages for sodium-ion batteries, substitution expectations continued to heat up, directly catalyzing a seasonal peak demand period in the industry chain. Against this backdrop, various segments of the sodium-ion battery industry showed differentiated growth trends. From materials to battery cell end-users, core product orders and production volumes benefited simultaneously. Enterprises engaged in frequent stockpiling and overseas expansion activities, laying a solid foundation for industry development in 2026.
