Donut Lab reveals world's first all-solid-state battery

Donut Lab, headquartered in Helsinki, Finland, has officially launched what it claims is the world’s first all-solid-state battery ready for mass vehicle production at the CES 2026. The new solid-state battery (SSB), called “Donut battery”, is scheduled to appear on the road in Q1 2026 through an electric bike made by Verge Motorcycles.

What’s special about the Donut solid-state battery?

The company claims their revolutionary mass-market-ready battery is much more durable, fire-resistant, fast-charging, has no liquid electrolyte and has a much higher energy density than a conventional Li-ion battery. As of early 2026, the Donut Battery is being marketed with the following production-grade specifications:

1. Energy density: 400 Wh/kg (30% higher than leading Li-ion batteries), enabling lighter vehicles and longer range, including a claimed 600 km range for the Verge electric bike
2. Charging speed: 0–100% charge in 5 minutes, with no tapering at 80% as with conventional batteries
3. Longevity: Up to 100,000 charge cycles with minimal degradation.
4. Full discharge capability: Repeated 100% depth-of-discharge without stability or degradation issues
5. Extreme temperature resilience: Retains 99% capacity from –30°C to 100°C
6. Intrinsic safety: Uses a non-flammable solid electrolyte, removing risks of battery fires
7. Geopolitical and environmental benefits: Made from abundant, non-toxic materials, avoiding rare or sensitive elements such as Cobalt
8. Cost saving: The Donut battery lowers production costs at scale
9. Design versatility: Can be produced in custom shapes and voltages, allowing it to act as a structural component in vehicle chassis or drone bodies

When is the solid-state battery coming to the market?

Donut Lab confirmed that Verge Motorcycles will be the first brand to put these “Donut batteries” on public roads. The batteries will be used in the 2026 Verge TS Pro and Verge TS Ultra, with deliveries beginning before March 2026.

The company stated at CES 2026 that the technology is already fully tested, validated, and installed in production vehicles. As of January 2026, Verge Motorcycles are available for order and delivery across Europe, the UK, and North America.

Other Donut Battery partnerships

Following the electric motorcycle launch, the Donut Lab’s technology is slated for broader commercial deployment using its business partnerships in:

• Defence platforms: Partner ESOX Group is integrating the battery into the X1 interceptor drone and X2 autonomous ground vehicle. A production ramp-up for these is planned for late 2026.
• Smart freight: The Cova Power Smart Trailer (a joint venture Ahola Group & Donut Lab) will feature the battery alongside Donut Lab’s hubless motors for electrified heavy transport.
• Modular platforms: WATT Electric Vehicles (WATTEV) has debuted a functional aluminium “skateboard” chassis using the battery, intended for multi-vehicle OEM use.

Developing the world’s first mass-market solid-state battery

Donut battery, which is the biggest battery breakthrough of Donut Lab was developed alongside its hubless in-wheel “Donut motor.” For the battery, the tech company partnered with Nordic Nano Group, a Finnish nanotechnology company. This partnership secured the core battery technology, which uses Atomic Layer Deposition (ALD) to “print” battery layers. This process removes the need for rare earth metals and flammable liquid electrolytes.

In November 2025, Donut Lab also launched DonutOS, a software platform designed to manage next-generation EV hardware, including the demanding charge and discharge cycles of its solid-state batteries.

What this means for the EV Industry

If this technology scales, it could dramatically change how EVs perform, charge, and last.  Solid-state batteries have long been called the “holy grail” of EVs, but until now, they were mostly lab experiments. Donut Lab claims to have removed the obstacles and compromises in the mass production of an accessible, safe, and durable solid-state EV battery.
