Changan Auto Reports Progress on Sodium-Ion Battery High-Power Electrode Tech

Changan's move matters less as a battery breakthrough than as a signal that automakers are hedging their dependence on lithium by pairing sodium-ion with swap infrastructure, a combination that could reshape entry-level and cold-climate segments. The CATL tie-up extends a relationship already central to Changan's electrification roadmap, concentrating technical risk and reward in one partner. The open question is whether the high-power electrode work moves from single-point progress to a manufacturable cell, and whether swap standards gain traction beyond these two players.
