QuantumScape’s solid state batteries are designed to solve many of the biggest issues in conventional lithium ion tech. By using a lithium metal anode and replacing flammable liquid electrolyte with a solid ceramic separator, the result is a safer, denser, and faster charging cell.

These batteries deliver more energy per kilogram, allowing electric vehicles to drive farther on a single charge. The absence of liquid means almost zero fire risk, even under extreme conditions. Their structure also maintains performance across a wide range of temperatures, making them suitable for more than just EVs. Future applications could include home storage systems, robotics, and portable electronics.

In short, this is not just an upgrade. It is a total rethinking of how a battery should work.

QuantumScape has opened its fully automated pilot line, Eagle, in San Jose to produce 5 amp hour prototype cells using high nickel cathodes and ceramic separators. Instead of building huge factories, the company plans to license its tech to automakers and battery manufacturers, making it easier to scale.

Backed by Volkswagen, QuantumScape’s roadmap starts with ultra high performance electric vehicles and motorcycles. Ducati has already showcased a concept bike using these solid state cells. The idea is to launch at the top of the market first, where cost is less of a barrier and performance is everything.

From 2026 to 2030, more models and partners will gradually adopt the tech. Experts predict solid state will not immediately replace lithium ion, but will complement it. Lighter, compact devices like smartphones and EVs will benefit first, while traditional batteries will still power large, stationary storage systems due to their lower cost.

QuantumScape also believes that being first is not the goal. Like Apple or Facebook in their early days, winning the market depends on building reliable performance over time. Solid state’s journey is just beginning.
