Sodium 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.

- djbusby 3y agoBatteries aren't pure sodium. Pure sodium bonded with something (eg: chlorine) is less explosive.

- 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.
