Sodium-ion vs. lithium-ion: Tracking the battery race in 2026

Consumers could soon notice cheaper electric vehicles as China moves to tax lithium‑ion batteries while exempting sodium‑ion units, a policy that may lower purchase prices and widen adoption. Manufacturers may also adjust pricing strategies, and the cost gap could shift sourcing decisions toward sodium‑ion chemistries in upcoming model years. The policy change stems from Beijing’s roadmap for next‑generation batteries, outlined by 스타뉴스, which describes a tax exemption for sodium‑ion cells and a levy on lithium‑ion packs.

CarNewsChina.com reports the exemption aligns with Hina’s target of 10 GWh of commercial EVs using sodium‑ion tech. openPR.com projects the sodium‑ion market to reach US$8.64 billion by 2035, while Yahoo Finance notes Aeson Power’s demonstration of the technology at All Energy Australia 2026. Interesting Engineering tracks the 2026 battery race, highlighting growing competition between sodium‑ion and lithium‑ion platforms and confirming industry momentum. With tax incentives and market forecasts signaling growth, the next question is how quickly automakers will scale sodium‑ion production and whether lithium‑ion pricing will adjust in response.

Observers will watch for additional policy moves in other regions and for further commercial roll‑outs that could reshape the battery supply chain.
