Theion is a German startup that is pioneering the development of a new type of battery technology, known as the Crystal Battery. This innovative product is designed to offer a high-capacity, long-life, and fast-charging solution for a variety of applications, including mobile devices, wearable technology, electric vehicles, and renewable energy storage.
Battery makers need higher energy density and lower-cost materials without relying on nickel, cobalt and large amounts of graphite.
R&D Focus
Sulfur crystal cathodes, lithium-metal anodes and high-energy solid-state batteries.
Innovative Solution
Direct Crystal Imprinting forms sulfur wafers for the Crystal Battery, paired with a protected lithium-metal anode and electrolyte system.
Solution Effectiveness
The company’s roadmap targets up to 1,000 Wh/kg, 1,500 Wh/L and more than 1,000 cycles. These are development targets rather than commercial-cell specifications.
