The next major step in electric-vehicle development is solid-state batteries. Compared to the lithium-ion batteries used in the current crop of EVs, solid-state units promise better range, quicker charging times, and a longer battery life.

Longer battery life?

 

To quote from the linked article

The other challenge facing solid-state batteries currently is battery life, with repeated charging taking a toll on early prototype batteries.

 

They may promise better battery life, but doesn't look like they're meeting that promise.

Toyota has perfect business vision and 2 decades of the best ever hybrid technology.
While 10 year old Leafs are heading towards scrap yards already, people are seriously considering 10 year old Toyota hybrid being a good buy (judging by posts in various social media groups I am part of)..
While some local dreamers are hoping there will be buyers for their home-cooked $20k+ EV replacement batteries, Toyota owner just hops into nearest Toyota dealer and gets brand new, $4k NZD genuine hybrid battery as a replacement for their tired one, which had already made 300.000kms.
We'll see about solid state batteries, timing is perfect, 2025 would be right time to get me a brand new Toyota...

Always with the promises. They cant deliver this, not yet, by 2025? perhaps. Right now they suck on cycles or temperature ranges or cost or charge speed, often on several fronts. 

 

 

 

We dont need them though, not to switch to BEVs..

$4k for a what 1.5kwh battery at best? How is that better than $20k for a 30kwh pack?

@RobDickinson -
how about one looks from the following angle:
$20k of non-cetrified, non-insurable vs $4k genuine battery to bring life into car with degraded battery....
There were no takers for $20k battery during last 3 years AFAIK while hundreds of already upgraded Prius and Camry are serving as taxi NZ wide.
Taxi do 300.000kms easily in 3 years and upgrade batteries at least once during it's lifespan of 500.000kms as Taxi.
One Auckland Uber Leaf driver (know him in person) had to change his 24kWh Leaf in just about 1 year for 30kWh Leaf which is already near it's end of life, so he has to change car for the 3-rd time in less than 5 years. He is using free Vector charger ..

Adding that up looks like 100,000 km life over a reasonable range with constant fast charging and very little cooldown. I guess that's kind of working out for him with tax deductibility and free fast charging or he would not continue to do that through several vehicles. Good to know, but this is not the way most people drive leaf.

I’m hoping that solid state batteries are not a case of “just around the corner”, a bit like fusion reactors. They know how to make it work, just need to iron out a few ‘kinks’ (for the last 50 years in the case of fusion).

 

I remember watching a trade show a couple of years ago where they were interviewing the head of a battery company. He was spruiking his new battery chemistry and design that promised four times the energy density and a smaller form factor. When he was asked how long it would be before it was in production he said “when we can stop it bursting into flames while recharging”!
