It'll be interesting to see whether there might be any kind of late-mover advantage for those who sat out lithium and begin pursuing sodium-based batteries now.

- recursive 3y agoSodium is not competitive with lithium for energy density, as measured in joules/gram. Sodium is good for stationary deployments. It's not good when weight matters.
- coffeebeqn 3y agoI wonder how well it suits home storage? Not being violently flammable would be a bonus for homeowners
- bogeholm 3y agoSodium + water is, unfortunately, violently flammable. Add water to elemental sodium, and you get heat, hydrogen gas and sodium hydroxide.

- SketchySeaBeast 3y agoI'm not sure how it's held in the proposed batteries, but isn't pure Sodium violently explosive when in contact with water?
- djbusby 3y agoBatteries aren't pure sodium. Pure sodium bonded with something (eg: chlorine) is less explosive.
- 0cf8612b2e1e 3y agoAny concentration of energy (gasoline, batteries, compressed air, etc) is always a potential bomb if it is released too quickly.
- leplen 3y agoThe safety problem with Li-ion batteries is the electrolyte is a flammable organic solvent. It is unrelated to the amount of energy stored in the battery under normal operation.
- specialist 3y agoSodium battery production mosdef benefits from lithium's advances. As you know, each new chemistry (and anode, cathode, etc) opens up new niches, use cases, and price points. Sodium won't displace so much as compliment lithium.
