RMIT engineers say they’ve tripled the energy density of cheap, rechargeable, recyclable proton flow batteries, which can now challenge commercially available lithium-ion batteries for capacity with a specific energy density of 245 Wh/kg.

You see a lot of stories about the next great battery tech. I’ve been seeing them for years, but still Li-Ion is the ubiquitous tech.
Even if energy density is only comparable, a battery with lower fire hazard and increased longevity is sorely needed. Li-Ion batteries simply wear out too fast. Considering the replacement cost (especially for EV applications), its a huge advantage for consumers. Then there’s a bonus of it being cheaper and more environmentally neutral which is also a big deal.
Of all the proclamations of a better battery, Na-Ion sounds like it might actually be a reality. That would make me happy to be rid of Li-Ion batteries once and for all. The only advantage they have is high energy density, they’re a fail on every other front.
