Sodium-ion

No car in this database uses sodium-ion cells, though unlike solid-state the chemistry is in production. Sodium-ion is the one most often named as the cheaper, more cold-tolerant alternative to lithium, and the first vehicles using it have appeared in the Chinese market rather than in the European and US line-ups this site covers. What it trades away to get there is set out in the sodium-ion reference. If a car here adopts it, the car will appear in this list automatically, because the chemistry is a field on the vehicle record rather than an editorial tag.
