When everyone talks about Sodium batteries, which sodium are we talking about? 😂
More technical things here: https://lnkd.in/g74uDfjF
The three are not interchangeable:
- Sodium-ion (Na-ion) — the lithium-ion look-alike: same cell formats and manufacturing logic, lower energy density, better cold-temperature behaviour; early commercial deployments now shipping.
- Sodium-sulfur (NaS) — a high-temperature (~300 °C) molten chemistry, commercially operating in utility storage for decades, but a different beast operationally.
- Sodium-nickel-chloride (ZEBRA) — another high-temperature chemistry, used in niche transport and stationary roles.
So when a headline says “sodium battery”, the first question is: which one?
