As someone who works in the battery industry I want to applaud them for calling the battery for what it is; semi-solid state. So many dirt bag companies keep throwing the term "solid-state" batteries around for prototypes they're working on but they dont exist yet, they're an aspiration. No company has figured this out yep so right now best you get is a semi-solid state that has improvements over existing chemistry but a whole bunch of additional caveats and negatives.

Oh lord it’s a fatbike. To call that an e-bike is a stretch. The pedals are mainly for show and to circumvent the rules for e-scooters.
It's a motorcycle
Don’t think so. You ever seen a motorcycle with cycling pedals?
That’s what “moped” used to mean. Also that “e-bike” does 750 watts. A good cyclist can do that for a couple seconds. And that’s about twice what a pro cyclist can do for sustained efforts. The thing is a motorcycle pretending to be a bicycle.
Yes that is what I said in my first comment
You called it a fatbike and an e-scooter. An e-scooter is an electric kick scooter and a fatbike is a bicycle with fat tyres which can be ridden on soft ground such as sand. In some countries the term fatbike is used to mean electric motorcycle with pedals and fat tyres, and a scooter can also be a kind of motorcycle/moped. Words are confusing.
Let me introduce you to the wondrous world of fatbikes and electric scooters.
You really don’t need to rack your brain wondering about whether I know what they are. As I said, they’re all over the place over here.
Nobody is pedaling this thing. Manufacturers want to make a motorcycle with broad appeal that doesn't require a license to operate and current e bike laws let them get away with it by slapping a crankset on it.
Yes that is what I said in my first comment
but then you....
Said it wasn’t a motorcycle? Well that’s because it isn’t. To call it a motorcycle would be too much honor. There are things in between you know.
Ever seen someone actually pedaling these stupid things?
Yeah they’re all over the place here. Some people pedal, most people illegally install a throttle and remove the limiter.
Yes. This one, for example
Apologies, I forgot that in this day and age I have to specify everything: have you ever seen one before* ?
Yes, there are quite a few other brands and models of these things that are marketed as bikes but are really motorcycles with cycling pedals
Yes that is what I said in my first comment
I’ll specify even further, have you ever seen an actual real motorcycle with pedals?
Yes, there are quite a few other brands and models of these things that are marketed as bikes but are actual real motorcycles with cycling pedals; I guess I saw the first one of these about 3 years ago but I'm sure they have existed for longer
Gee I’ll bet your mom thinks you’re a really funny guy!
For starters, lifespan is dramatically improved. The Revv1 EVO’s battery is rated for over 1,200 charge cycles before dropping to 80% capacity. That’s more than double what you’d expect from a typical e-bike battery, which often lasts around 500 cycles
Let me introduce you to my friend LFP. 5k-10k cycles, easily.
The battery can fully recharge in around two hours, thanks to its chemistry AND Ride1Up’s inclusion of a high-power 9A charger, compared to the typical 2-3A charger typically paired with most e-bikes.
That's nothing to do with chemistry. Typical NMC batteries can charge way faster than that.
Many semi-solid state battery cells already pass the puncture test, in which a nail driven through the cell won’t cause a fire or explosion. Try that with a typical e-bike cell, and, well… you’d better do it in an open and safe area.
Also not a problem with LFP.
You are correct but the energy density is half. For this huge bike in the article you probably could get away with it but for a proper small/light ebike LFP doesnt make much sense because they're so heavy.
How is the energy density of the semi-solid?
This is a good move in the right direction.
