for the last 3 years I've been reading of these breakthroughs. They are not just 2x Lithium Ion, they are usually 10X!! or in this case 60X creating an "EV Range Breakthrough" to quote the title exactly.

You have a 60x EV Range breakthrough - and you are still a small company not snapped up by some monster. How in the HELL is that possible. 60x range is 20,000 miles for the tesla Model 3. How is this amount of energy even carried safely?

I've become jaded to these announcements. Glad someone is coming out with a checkbox for them.

Note that for EV's COST has become a key driver - 315 miles range is "good enough" if you get to leave your house every morning with a full charge. Hopefully the 60X improvement creating this "range breakthrough" translates into a 60x cost reduction given you can use a much smaller battery for the 315 miles.

I was watching an episode of Nova on PBS about "Search for the Super Battery" and it was pretty enlightening. The basic lithium battery can store a lot of energy but due to dendrite formation it can short circuit and fail catastrophically. So they made some modifications to improve its safety while compromising other parameters and we get an lithium ion battery. But scientists are learning how to improve its safety without degrading other properties too much. They play around with different anode and cathode formulas and the separator membranes between them.

So, if you are interested in lithium ion batteries, their problems, and current industry solutions, I can think of no better youtube channel then "the limiting factor".

Here's his video talking about Tesla's new silicon/lithium tech. https://www.youtube.com/watch?v=AL6xp4fLdFw

Looks like an interesting video. Thanks for the link.

It was 3x on capacity, 60x on charging speed. Which, if true would solve the two main problems with electric vehicles.

The only 60x in the article was charge time improvement.

Even the battery techs that show the most promising (in-lab, no guarantee of ever coming to fruitition) stats like lithium-air only have energy density roughly equal to or a bit lower than fossil fuels. Anything that actually blew that away by such huge would be worth billions if not trillions.

The article title and within the article clearly state "60x faster charge" which still means a hypothetical 315 miles of range until which point they also claim "60x more battery capacity."
