#2Nice, when can we use them for phones and laptops lasting 72% longer and without fire risk?
Genuine question, because optimistic battery articles have been popping up for decades, but here we are still with lithium ion in practice.

#3Research Vs Reality are quite often decades behind in physical world.

News about news battery chemistry is interesting, but it's not meaningfully correlated with our ability to produce practical batteries at scale.
If there are existing manufacturing processes that can be leveraged to build cells with this chemistry—and do so economically—then commercialization could happen very rapidly.
Otherwise, it's likely to be filled away until future manufacturing technology comes along, which may be "too late" if even better or more economical options exist at that point.

#5Surprised how "dead" this industry is. I remember having Lithium-Ion batteries since I was in high school which was more than 20 years ago (and some Li-Po until then). Everything is leaps and bounds since then but not the batteries. Seems like a massive disconnect to me but I'm no chemist or researcher in this field.

#6Solid state might share the fate of Betamax.
There was a post a while ago about a small scale battery manufacturer named Amprius, which reported 500Wh/kg batteries:

Thing is, the company is producing 450Wh/kg batteries NOW and they're planning on scaling up their manufacturing capacity to 5GWh:

This solid state news piece is exiting, but the real revolution is happening in the background, with LFP achieving decent densities without sacrificing cost or longevity and silicon anode batteries reaching large-scale commercialization as we speak.

#7"...the problem they face going through cycles of discharging and recharging in a stable way."
They suffer from poor wearing like almost all new battery technologies. Until that's solved they aren't useful.

If you read the article to the end it does actually offer reasonable perspective on this, pointing out that there are many other challenges left to solve before even getting to a prototype scale. TL;DR It's a promising step in the direction of solid state batteries.

#9Isn't this what Quantumscape is already betting on ?

Energy density is ~8 times higher than in 2008 at 1/10th the price. That's more progress than we've made in single-core performance in the same timeframe.
