Explore how solid state energy storage reaches the road, offering rapid charging, high density, and stable performance in production electric motorcycles.
As electric mobility scales toward faster charging and higher energy density, battery technology has remained a critical bottleneck. Many solid state concepts have shown promise in laboratories but failed to reach real world deployment, leaving manufacturers reliant on conventional lithium ion systems with inherent safety and durability limitations.
Donut Lab announced the availability of an all solid state battery designed for immediate use in OEM production vehicles. The battery is already operating under real world conditions and will power all model Verge Motorcycles. Unlike earlier solid state efforts limited to prototypes, this solution is being deployed directly in production models including the Verge TS Pro and TS Ultra.
The battery is engineered for high performance and scalability, delivering an energy density of 400 Wh per kilogram while supporting full charging to 100 percent capacity in five minutes. Its solid electrolyte design removes flammable liquids and eliminates thermal runaway risks, addressing long standing safety concerns in electric vehicle applications. The system is designed for repeated full discharge without measurable degradation.
Key features of the battery include:
- Energy density of 400 Wh per kilogram
- Full charge in five minutes
- Up to 100,000 charge cycles with minimal capacity fade
- Stable operation from minus 30 degrees Celsius to above 100 degrees Celsius
- Solid electrolyte design without ignition risk
The battery uses abundant and geopolitically safe materials, avoids rare elements and is designed for lower cost compared to lithium ion alternatives. Its modular architecture supports flexible sizing, voltage configurations and unconventional integration approaches across vehicles, drones and structural platforms.
Marko Lehtimäki, CEO of Donut Lab, says, “While the advantages are obvious, the future of solid state batteries has been a moving target constantly delayed when companies working in electrification are asked about when they will become a reality.” With solid state batteries now operating in customer vehicles, the technology marks a significant step toward faster charging, safer energy storage and scalable electrification.
