Semi-solid-state batteries are finally breaking into the real world, and they’re starting with E-bikes.

This tech has long been hyped in the EV world for its potential to deliver faster charging, more range, and better safety for cars.

Now it’s moving from concept cars to production bikes, promising to change what electric two-wheeler bikes can do.

And the first company to make it happen is T&D, a spin-off from e-mobility specialists, Bafang, carving out a niche in a new frontier.

Why are semi-solid-state batteries so important?

Any EV fan would be excited to see that semi-solid-state batteries are on their way – this time for E-bikes, rather than cars.

Unlike standard lithium-ion packs that rely on a liquid electrolyte, T&D’s battery replaces most of that liquid with a thicker, gel-like material.

This creates the Hannah Montana of the EV battery world – a hybrid between traditional and solid-state batteries that offers the best of both worlds.

These snazzy new batteries have a very impressive payoff; the energy density jumps to around 250 to 350 watts per kilogram, compared to the 150 to 250 watts per kilogram that most E-bikes use today.

That means either a smaller, lighter pack for the same range, or the same size pack for much longer rides.

Safety is also a big win with these, and the company says its cells can pass nail penetration tests without catching fire, something not many lithium-ion batteries can survive.

The E-bikes are also designed to last longer, holding up for around 1,500 full charge cycles before dropping to 70 percent battery capacity.

This could change the market of E-bikes as we know it

The potential impact on E-bikes is massive because smaller, cooler-running batteries could free up E-Bike builders and creators to create lighter frames, sportier models, and sleeker designs.

It also opens the door for faster charging and longer trips – two of the biggest challenges for bike riders in busy cities today.

T&D hasn’t revealed which brand will use the new battery first, but production is already starting, and it’s so exciting.

If it performs as promised, semi-solid state power could mark the beginning of a new era in electric transport, one that blurs the line between E-bikes and regular EVs.
