🔋 Semi-Solid-State batteries revolution!
- Thread starter BikeBert
- Start date
You've clearly not read this thread, but there's no such thing as solid state batteries.
All current batteries are technically already semi solid state batteries, you are drinking the marketing koolaid being set in front of you.
Idk crap about batteries and yes I just regurgitated what I saw in a YouTube video that was touting the new battery tech
Sorry, it gets old, the marketing shenanigans...
I mean I’m sure it’s not the exact same as their last battery, so could be something there. Just figured you battery nerds would be interested in digging into it. I honestly don’t care. Figured some people on here would find it worth looking into
I digged a little. Rumors are (and before you guys freak out I’m not saying this because of more power, just want to see if this is crazy numbers for batteries that can be scaled down to our application for lighter/more efficient not more power)
78v 45ah 7C discharge and possible 25kW peak. 3.53 kwhr. 33lb battery. People saying to expect 50% more range.
No clue what those numbers mean if scaled down to our 600-800wh applications, but hopefully better than what we have?

The cells currently used in most e-bike/e-moto batteries are at least one, if not several generations behind.
Simply changing to molicell 65's would result in a capacity and charge speed upgrade for every current battery, including the avinox's. And they drop right in to the existing battery packaging formats. They've been commercially available for over a year.
E-bike's are one of the last places you will see new battery tech.
Hence my eye rolling at the "new" semi solid surron batteries...
They are almost certainly simply using this off the shelf cell.
Alright my bad. Thought I was breaking some news for you guys haha. I’ll see myself out.

CATL chief: solid-state batteries at 'level 4 of 9,' no leap until 2030
CATL chairman Robin Zeng says solid-state batteries are only at 'level 4 of 9' and won't reach mass production before 2030, cooling industry hype.

There actually is such a thing as semi solid state. It has a definition.
If you mean the Molicel M65A, that's sort of true, but it's really hard to get hold of them, especially in large quantities. What's definitely true is that most brands have chosen high-ish capacity, slow-charging cells (usually the LG M58T) rather than lower-capacity, fast-charging ones, which is not good for those of us who use more than one battery's capacity in a day.

I'd say if you had to choose one, that capacity > charge speed. I think the minority of users are charging mid-ride.

Its not a super dramatic improvement to Wh/Kg vs. the current status quo, but did any of you guys see the new WeLion batteries shown at Eurobike? According to Seb at Pinkbike "WeLion's 1,080 e-bike battery is the same size and weight as a Bosch 800 Wh battery (around 4 kg). It packs in over 25% more energy per unit mass (264 Wh/kg) thanks to semi-solid-state pouch cells with a gel rather than a liquid electrolyte.":
