Solid-State Batteries: The Biggest Upgrade Scooters and Power Chairs Have Ever Seen Is on the Way

Byeasymed

Status: Announced: in pilot production now. Not available for scooters or power chairs yet.

Lighter, safer, faster to charge, and built to last

Ask any scooter or power chair owner what they’d change, and most will say the same thing: the batteries. They’re heavy, they take all night to charge, and they wear out sooner than anyone expects. Solid-state batteries could fix all of that at once. After decades of fixing this equipment, I think they’ll be the biggest single upgrade mobility devices have ever had.

I can’t wait to get these on my bench: load tests right up to the spec limits, then real road tests with portable recording test equipment hooked to the batteries. When I do, I’ll post the results here.

What “solid-state” really means (it’s still lithium)

Here’s the part most videos and articles get muddled. Every battery has an electrolyte, the material that carries charge between the two ends of the cell. In today’s lithium-ion batteries that electrolyte is a liquid. A solid-state battery replaces that liquid with a solid, a thin layer of ceramic, glass or polymer.

So yes, they’re “dry” batteries. But most solid-state designs are still lithium batteries. Many actually use more lithium, not less. “Solid-state” describes how the battery is built, not a new chemistry. (If you’ve heard about batteries with no lithium at all, that’s sodium-ion, a different technology.)

What it could mean for your scooter or power chair

  • Much lighter battery packs. Solid-state cells promise to store far more energy for their weight. On a travel scooter, the battery is one of the pieces you lift every single time. A much lighter pack could make breaking down and loading a scooter a one-person job for more people.
  • More range, same size. Or keep the weight and go much farther on a charge. Running out of power halfway across a parking lot becomes a lot less likely.
  • Faster charging. Car makers are targeting fast charges measured in minutes, not hours. Scooters won’t charge that fast on a home charger, but “plug in overnight” could become “plug in over lunch.”
  • Safer. The liquid electrolyte in today’s lithium cells is what burns when a battery fails. Taking it out greatly reduces the fire risk. That matters for a battery sitting under your seat or charging in your living room.
  • Longer life. Solid-state cells are expected to handle many more charge cycles. Today’s sealed lead-acid (SLA) batteries often need replacing every year or two. A battery that outlasts the scooter would save owners real money.
  • Better in heat and cold. Solid electrolytes are more stable across temperatures. Here in Arizona, heat is one of the biggest battery killers I see.

So when will scooters get them?

Here’s where things stand in late 2026:

  • Cars come first. Toyota is targeting its first solid-state vehicles around 2027–2028, and QuantumScape has been shipping sample cells to car makers for testing. Big pilot production lines are running in Japan, Korea and China.
  • “Semi-solid-state” is already arriving. This in-between version uses a gel-like electrolyte. It’s showing up in some e-bike batteries and power banks in 2026. E-bikes are the closest cousin to scooters, so this is the one to watch.
  • Scooters and power chairs come after that. New battery technology starts out expensive and goes where the big money is first: cars, then phones and e-bikes. Mobility equipment usually gets it once prices come down. My best guess is a few years behind e-bikes. Watch for the major makers to announce it first on their premium travel scooters.

A repair tech’s take: what will change for owners

  • You’ll need the matching charger. Every battery chemistry needs a charger built for it. Never charge a lithium battery with an SLA charger, or the other way round. Solid-state will be no different.
  • A battery management system (BMS) comes along with it. Like today’s lithium packs, solid-state packs will have built-in electronics that protect the cells. When they fail, it’s usually the BMS, not the cells, and that’s the kind of repair I expect to see more of.
  • Airline rules probably won’t change right away. Because solid-state batteries are still lithium, expect airlines and regulators to treat them like today’s lithium batteries until the rules are updated. Always check with your airline before you fly with a mobility battery.
  • Don’t buy “solid-state” on a label alone. As the term gets popular, expect products that stretch it. Look for real specs: the chemistry, watt-hours, cycle rating, and whether it’s full or semi-solid-state.

I’m also curious how well solar charging will pair with these new batteries. If they really charge faster and waste less energy, solar could become a practical way to top up a scooter away from home.

What you can do today

You don’t have to wait to get most of these benefits. Lithium iron phosphate (LiFePO4) batteries are available now for many scooters and power chairs. They’re much lighter than SLA, last far more charge cycles, and are one of the safest lithium chemistries. They’re the closest thing to solid-state you can buy today.

We’ll update this page as solid-state batteries move closer to scooters and power chairs.
