Solid State Batteries Are REALLY Here: Yoshino Power Station

Corrections:
00:05 - I've received some comments that this may not be a true solid state battery, but a semi-solid state battery based on testing from a third party company. I'm currently investigating and will update this video as soon as I have more information. I'm also working with a friend/fellow YouTuber to do a breakdown of the cell chemistry.

Matt, I think you’ve reached the point of this channel, where you should be buying two of these things, one to show off, and the other to do a tear down on. Would have really loved to have seen the actual size of the battery, compared to all the other electronics inside.

[napalmenthusiast]

As an engineer once said "The last of the old will always be better than the first of the new" but they already made a promising product thats somewhat competitive in the market

[jackhemsworth]

For a first gen product to be even this close to lithium batteries that have been around and refined for decades now is really something.

[solarmax]

We have been using a Yoshino B2000 for around a year now. We use it as electricity backup for medical equipment in our home. Everything has been just fine for us so far.

"It's a bit of a charged topic" he says, with a straight face. This man is a dad. I guarantee it

[Casper]

I LOVE that at 2:45 in the Yoshino video the teenage daughter gives zero fucks that Dad got the TV working.

[mika]

The fact the first gen product is actually able to compete and not just a tech demo is very promising, hope it continues to improve so we can all have safer and lighter batteries

It is bizarre how angry people are that Yoshino wasn't able to live up to the claims that researchers have made about the *potential* of solid state batteries, which is totally unrealistic for a first generation product. It's entirely possible that not all claims made by researchers will *ever* materialize. The fact that this is competitive on the first generation is amazing! Thank you Matt for telling us about this in this unbiased and informative review.

I love the 2:49 stock footage where the dad is happy the TV is on but daughter couldn't care less.

What was the point of this video? It's an analysis of a product based entirely on the manufacturers claim. Is this even a real solid-state battery? Why not tear it down and see for sure if there is no liquid electrolyte? Why are you doing energy density measurements based on the entire product weight and not the weight of the cells themselves? Have you tested to see if the maximum energy capacity listed by the manufacturer is accurate?

[JLarky]

Two modes of a random person on the Internet learning about something new:
- this is not going to work
- I already knew it

[MrDLYouTube]

"It's bit of a charged topic"...oh nice one sir.

[bosstowndynamics]

Matt, have you done any kind of testing to confirm these are actually using solid state cells? Just eyeballing the specs it seems to me that all of the most immediately testable properties of these devices (weight, capacity, power in/out) could all be achieved with conventional NMC lithium ion cells, at the cost of much shorter service life and theoretically increased safety concerns compared to their LFP competitors

[dominique___]

I've been using my EcoFlow Delta Pro for almost 3 years. (Early-bird kickstarter). I love it. We boondock A LOT with it. When I'm boondocking, it's in the RV. When at home, we use it 24/7. So moving it back and forth from the RV is a challenge. The Yoshino being half the weight has me SUPER intrigued.

[curbthepain]

I want one of these for my scooter. I want to be able to head to the half way point of my journey, have a coffee or lunch and charge up, then finish my trip.

[Elijah-]

I'll wait until JerryRigEverything has stripped it apart to verify that it is authentic. 😂

[lucretius]

In case anyone is wondering, Yoshino is not a Japan brand.

[websterleone]

It *is* nice to see actual solid-state battery products. I'm just disappointed that I likely won't be able to get drop-in replacement batteries for my massively oversized UPS by the time I have to replace them next year. 12x 9Ah SLAs are a lot and I'd love replacements that have the promises of longer life, longer run-time, and lower weight.

[RoysTechStuff]

What is the usable power, though? In my experience, lithium-ion based power banks only give you around 70% of the rated capacity when put to practical use. Does this solid state device show similar performance?
