UCI scientists found a way to make Lithium-Ion batteries lose no capacity over 100,000+ charge cycle

Posting this here, but it is equally important for the motor industry I guess, perhaps even more so since there are concerns over battery swap costs for EVs and whatnot.

"Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it," Penner, chair of UCI's chemistry department, said in a statement. "She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity."

"That was crazy," he added, "because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most."

So will this now change the thoughts in the minds of many who look for phones with a swappable battery?

Effectively this means sealed off batteries are a no brainer. With fast wireless charging and wired quick charge technologies common place these days, I think replacement batteries will soon become a thing of the past.

This is also excellent news for the used phone market. No more fear of buying a used handset with a battery that might have degraded capacity if it's 12-24 months old.
 
I think I paid £10 for a spare battery for my LG G3, I guess for Electric Vehicles this will be quite significant
 
The only reason I bought phones with a swappable battery was so I could go on a multiday trip (camping at a race for example) and could easily just stick the other battery in when the one in the phone was running out.

I never considered a phone because I could swap a battery due to the battery dying. It's just never been a concern to me - if it dies in warranty (highly unlikely) it will be swapped and if it dies outside of warranty then I'd probably be approaching the upgrade-itis state for an upgrade excuse anyway.
 
Doesn't do anything to change my thoughts - sometimes batteries die and its much easier to change one out than send it away for RMA or whatever and there are times when having a spare charged to swap over "in the field" has been useful as well.

There is no good reason IMO not to have a swappable battery not like there are any real downsides with having a swappable one.
 
^^ The only upside is a better looking phone and maybe a stacked battery.

But yeah, you can still have a good solid design and build with a removable cover. No thank you to a glass or even metal back. Give me wood/leather/sandstone.

I think it's one of the more realistic things that will become common unlike the many others that are announced, then brushed under a rug (read: paid off and killed by those with vested interests in the competition) :p

Phone batteries maintaining capacity for years gives consumers one less reason to upgrade. With screen sizes no longer increasing and with the speed of performance improvement falling why would phone manufacturers score such a big own goal?

Hmm. This is my own experiance so im clearly showing bias here BUT they need to work on making the batteries last at least 2 years before worrING about people upgrading . Spooky how quiet a few of us with note 4's had to replace our batteries after 12 months. It would be a damn sight more inconvenient if it wasn't removable.

My phone has had 420 charges in 2 years, I really doubt i'll need 100,000 tbh. I'd rather have a battery capacity increase.
 
Surely this is a non starter, I can't think of a single example of where I've changed a product because the batteries life cycle has ended.

What we need is brand new battery tech, one that charges faster, lasts longer and plays nicer in everyday life, Graphene + Supercapacitor batteries as a possible future example.
Not a way to extend the existence of already planet killing tech that really isn't very friendly to start with.

It's also unmarketable and won't attract investment. What would the pitch be to the Dragons "hey we've designed a technology that means you'll sell far less products and reduce profit"......

Yup had to change my youngest's Note 4 battery after about a year, it was ridiculously bad how fast it ran out of a full charge.

Loads of things have only just changed in the few years to using Lithium-Ion batteries instead of crappy NiCad rechargeable batteries

This breakthrough only worked for small capacities according to a researcher on reddit, nothing like li-ion density. While it's possible it could be scaled up, i think this will be far away otherwise they would have mentioned it.
 
those affected will be the battery producers themselves. they will be reluctant to produce it in the first place using the new technique. only time will tell.
 
Phones get passed onto to other family members all the time. A flagship phone today should be good for upto 5 years for less demanding users. Performance wise.
