Semi-solid state batteries are coming to the e-bike industry – and for real this time

[Dave Rocks]

What it means for riders​

If the early claims hold up in real-world use, riders could see several tangible improvements.

First is longevity. A battery that lasts 2–3 times longer fundamentally changes ownership. Instead of planning for a costly replacement after a few years, riders could realistically keep the same battery for close to a decade.

Then there’s charging. Faster charging without long-term degradation could make e-bikes far more convenient for daily use. Think less overnight charging and more “top it off while you grab lunch” type of usage.

Cold-weather performance is another huge win, especially in regions where winter riding has always meant compromised range. A battery that holds onto more of its capacity in freezing temperatures makes e-bikes more viable year-round transportation, and more than just fair-weather tools.

And finally, safety. Reducing reliance on flammable liquid electrolytes could significantly lower the risk of thermal runaway events – something that has become an increasingly important issue as e-bike adoption grows in dense urban areas.

Interesting indeed. I've been expecting/waiting for this. Wonder if Giant will offer retrofit batteries in this format...

Odd no mention on weight which was to be an advantage.
But the real question is... will they get FM?

Yeah I'd have thought the higher density/lower weight would be first where bikes are concerned.

It is interesting all the pictures in the article showed e-motorcycles.

I guess that's the take away from the illiterate

strange, none of those are really major benefits to me - i’ve never had a well cared for battery die from cycles, have to be replaced, explode, etc. and i don’t ride in a cold climate,

but less weight per kwh would be a HUGE benefit!
