here we go again with another amazing battery breakthrough! remember fuel cells and how they were going to power your cellphone _real_ soon now. exactly.
I can tell you now why there will never be a battery with a significantly greater energy density than we have now. It's because such a thing is also known as a "bomb".
There are solutions, of course, nature solves this problem with, for example, sugar. But what you need is a metabolic process for the release of energy.
Anything that's a solid lump of something won't work. don't invest in this.
- jakobegger 11y agoDid you even take time to read the article? Using sodium instead of lithium isn't about making higher density batteries; it's about making cheaper batteries since sodium is much more abundant than lithium.
- igravious 11y agoI thought I read somewhere that in terms of the percentage cost of a battery the raw materials are fairly insignificant. Don't remember off the top of my head, I'll have a hunt for some sources and edit this comment. Maybe we'll get a multi-material battery market, that'd be cool.

His plan is to consolidate everything to one place and get raw materials from the mines and produce batteries on site at his gigafactory.
- ghshephard 11y agoThey didn't note energy density as a benefit of these batteries. They noted cost, availability, and recharge cycles as principal advantages.
