Pass the salt?

Sodium-ion battery beats lithium for cost effectiveness

Of course, this is years off, but...

Thoughts?

I like salt, so I'm all for it. I wonder if a sodium ion battery causes less damage to the environment.... Will probably investigate this at some point when I have a moment. Even if it's years off, I'm thinking it may be a good thing....

Maybe Sodium-Ion batteries will be more forgiving when pushed to high limits. Lithium is a volatile element.

In a new study, researchers have designed and fabricated a sodium-ion full-cell battery that uses sodium titanium oxide nanotubes as the anode material. In addition to greatly reducing the safety risks compared to sodium-ion half-cell batteries, the new battery can store nearly the same amount of energy in a given volume as today's state-of-the-art lithium-ion batteries. Although the new battery's energy density (220 Wh/kg by itself, or an estimated 130 Wh/kg when fully assembled) is not as high as that of the best sodium-ion half-cells, it is the highest achieved so far for sodium-ion full-cell batteries. A high energy density ultimately translates to longer battery lifetimes and—when used in electric vehicles—longer driving ranges.
