- SOLiTHOR achieved 465 Wh/kg energy density in multilayer pouch cells.
- Its manufacturing process reduces production complexity and costs.
The SOLiTHOR solid-state battery technology has reached a significant milestone in advanced energy storage development. On June 10, the company announced the integration of its proprietary Solid Composite Electrolyte with a high-loading cathode featuring an areal capacity of 8 mAh/cm². This achievement enabled the company to reach an energy density of 465 Wh/kg and 1,400 Wh/L at the stack level in a pouch-cell configuration. Such performance highlights the growing potential of solid-state battery architectures to deliver higher energy storage while supporting next-generation electric mobility applications.
The company's proprietary sol-gel chemistry introduces an alternative approach to manufacturing solid-state batteries. Unlike conventional methods, the process eliminates the need for liquid electrolyte filling while maintaining high energy density and efficient operation across various conditions. The technology has demonstrated stable performance under different operating temperatures, c-rates, and cycle life requirements. By simplifying manufacturing while preserving electrochemical performance, the approach offers a promising pathway for scalable production of advanced batteries.
Performance validation in multilayer pouch cells has shown encouraging results at 25°C. The battery supports high discharge rates with minimal capacity loss, indicating its capability to handle demanding operational conditions. Durability testing further demonstrated strong cycling performance, with more than 80% of the original capacity retained after over 500 charge-discharge cycles in a 1 Ah multilayer pouch cell. These results suggest the technology can support long-term reliability requirements across various electrification applications.
Another key advantage lies in manufacturing compatibility. The production process is designed to work with existing roll-to-roll battery manufacturing methods, allowing easier integration into current industrial facilities. By eliminating the electrolyte-filling step and reducing formation and aging time, manufacturers may benefit from lower production costs and improved throughput. Such compatibility can accelerate commercialization while reducing barriers to large-scale adoption of solid-state battery technology.
