Stromer Teases the ‘Holy Grail’ of Batteries with Solid State Ceramic eBike Battery

It doesn’t take long walking around the Eurobike show halls to realize that eBikes are already here in a big way. All of those eBikes lining the show floor are running similar lithium-ion battery tech… for now. 

Like in the EV world of cars, battery tech is a hot topic. Sometimes quite literally as “eBike’ batteries have gone up in flames. 

Over at the Stromer booth, they were teasing what they consider to be the holy grail of battery tech – a lighter, safer option, that also charges much faster.

While it’s still just a concept, Stromer has been working with TD Hitech as a supplier to create a new solid-state ceramic ebike battery. Made from layers of ceramic, the claim is that it will enable fast charging in an hour or less. 

Perhaps more importantly, the ceramic plates could be more durable than lithium-ion cells and can be charged even if plates are broken. The battery tech will also supposedly allow for charging in colder conditions, down to -20c. As a bonus, it could also yield a lighter battery as well.

Update: While they failed to mention it while I was at the booth, Stromer reached out to us recently to let us know that they actually had a rideable prototype of an ST7 eBike with a solid-state ceramic battery at the show.

For now, this is all just a concept but Stromer says it could be here as early as 2025.

I think that many people would opt for the heavier lithium iron phosphate batteries on commuter bikes if given the option. Because of the steady voltage and the high amount of cycles, you could just lower the capacity and offset the higher weight. If you tell a customer that they last longer and are safer, they will choose it (for non-performance bikes)

Every new battery tech article I’ve read over the last 10+years has it coming to market just around the corner…then like a fart in the wind I never hear about it again.

It would be great to have a battery that weighed half what they do now. Glad somebody is pushing at boundaries, despite apparent rampant skepticism.

good to know that it works when broken, what else does it do ?, any info about weight, capacity of this pile of plates? can you serve pizza on it ? what about a greek wedding ? OPA !

We need new battery tech for traveling and apartment living as lithium is now being banned…

Sodium batteries are on the way with factories being built in Germany and Hungary

As much as I don’t like it when accessibility for bikes gets restricted, I can’t blame people for not wanting ebikes inside buildings. I put my battery inside the stove whenever I charge it.

Cycling business loves adding the word ceramic and an extra zero to the price of their products.

Toyota, of all companies, just announced the same thing. Looks like this may really be in the works.
