Too bad we are not mining the lithium here just because doing so is an environmental nightmare. But I’m sure we can buy it forever from the Chinese.
So how big are the copper wires going to be to charge these new batteries quickly?
Who’s building the nuclear power plants to charge these things?
The article leads with: "These batteries are capable of charging in as little as an hour...".
We already see that. At a 150kW DC fast charger my EV charges from 15% to 80% in 15 minutes (closer to 10 minutes with a 350kW charger, though admittedly the battery charges that fast only in the first few minutes when the charge level is low). I can charge it completely to 100% in 30-40 minutes if I'm eating dinner plate lunch or otherwise taking a break to make it worth waiting an extra 15 or 25 minutes to top out the last 20%.
So the future is getting a Fast Charge refill in only 1 Hour:-)
I do not believe that Lithium is the future. It is too rare a material to be used on a worldwide basis for a very long time.
The battery that will work best will be something that makes use of material that is relatively common and abundant, like sodium.
I view the use of lithium as very limited.
With these monthly technology breakthroughs, batteries are now unlimited in capacity, unlimited in number of charge cycles, last for a minimum of 100 years, hold its charge for 20 years on the shelf, very light weight, very small, and cheaper than than a bic lighter!
Fast charging you say. And much does this fast charging make this battery die sooner? This always seems to be a problem.
As in you buy a new Tesla automobile. If you only charge it up via fast charging. You will have to replace your battery years sooner. A relative goes in for this EV stuff. He has a charging station in his garage. I must assume that you can regulate the charging speed at home? Right? So that you can dial it back. To where his Tesla (Chevy Bolt too) get charged more slowly over 8 hours.
New way to start house fires?
The difference is no dendrites. So the battery can be fast charged every time and never lose any capacity and last 20 or 30 years or more.
Yeah, ok.
lithium? Pshaw...
I’m waiting for the dilithium crystals. Then we can use the matter/antimatter reactor.
“With these monthly technology breakthroughs, batteries are now —— cheaper than than a bic lighter!”
And strike up a fire like a bic lighter, and burn the garage and any adjacent structures to the ground.
Like a previous poster said, they are not the future.
Lithium is too rare, too costly, too heavy and batteries made from such are fire hazards.
Brave soul. Hope his insurance will cover it.
I’m afraid to ask - is this “just around the corner”?
So tired of all the “breakthroughs” that are not commercially viable.
The west is exploiting the Third World for these resources while our banks deny them the loans to build power generation.
This is western enslavement of nations that will hate us for generations because we kept them in poverty instead of lifting them out.
“What’s the big deal here? I’m not getting it. Am I missing something?
The article leads with: “These batteries are capable of charging in as little as an hour...”. “
From the article...
“This new approach, led by University of California San Diego engineers, enables charging of lithium-metal batteries in about an hour, a speed that is competitive against today’s lithium-ion batteries.”
I guess you have lithium-ion.
So what’s the advantage of lithium metal? Higher power density? Lower cost?
True. But really enjoyed your tag!! LOL
Lithium metal is a surprisingly highly reactive element, much like sodium and potassium. When lithium metal comes into contact with water, it forms lithium hydroxide and hydrogen gas, and a LOT of heat, which then ignites the hydrogen in the presence of oxygen.
One of the reasons it is so hard to extinguish a fire ignited by a lithium battery.
