ProLogium is advancing its next-generation energy storage through a portfolio of proprietary technologies designed to overcome the long-standing challenges of solid-state batteries. The company's lithium ceramic battery platform combines advanced materials, novel cell architecture, and scalable manufacturing processes aimed at delivering higher energy density, enhanced safety, and ultra-fast charging capabilities.
ProLogium's battery platform includes its proprietary Logithium® electrode structure technology, which serves as the foundation for the company's current and future battery generations. The architecture employs a silicon-based frame adhesive and a unique cell-layer design that improves mechanical stability, enhances moisture resistance, and prevents edge short circuits. The technology also supports high-speed roll-to-roll manufacturing, enabling efficient large-scale production.
Another key pillar of the platform is ProLogium's 100% ceramic separator technology. Unlike conventional polymer separators, the all-ceramic structure is composed of non-flammable inorganic oxides, providing intrinsic safety and superior structural rigidity. The ceramic separator is designed to address conductivity and brittleness issues commonly associated with oxide-based solid electrolytes while maintaining compatibility with continuous roll-to-roll manufacturing processes.
ProLogium has steadily increased production capabilities for this technology. After developing coating-based ceramic separator fabrication in 2013 and establishing a pilot roll-to-roll line in 2017, the company launched a gigawatt-hour-scale production line in 2024 capable of coating speeds of 30 m/min. Future manufacturing targets aim to raise production speed to 55 m/min, further improving throughput and commercial viability.
A major technological breakthrough within the company's battery roadmap is its SF-Ceramion superfluidized all-inorganic solid-state electrolyte. The electrolyte is engineered to provide both intrinsic and active safety. Because it is non-flammable and does not release combustible gases under high-temperature or high-voltage conditions, it significantly reduces the risk of thermal runaway. In addition, the electrolyte can actively stabilize electrode materials during abnormal operating conditions, providing an additional layer of protection.
The electrolyte achieves room-temperature ionic conductivity of 57 mS/cm. The conductivity is reported to be several times higher than that of conventional liquid electrolytes and sulfide-based solid-state electrolytes. The material also maintains high discharge efficiency at temperatures as low as -20°C, making it suitable for applications operating in harsh climates.
The company is also pursuing higher energy densities through a 100% silicon composite anode. Silicon offers significantly higher lithium storage capacity than conventional graphite anodes, enabling energy densities of approximately 380-400 Wh/kg and volumetric energy densities approaching 940 Wh/L. The architecture further supports rapid charging performance. Under a 400 V system, ProLogium's Gen 3 batteries can charge to 80% capacity in 8.5 minutes, while Gen 4 technology reduces the charging time to 6.4 minutes, with cycle life exceeding 1200 cycles within the 10-80% charging window.
ProLogium's Gen 4 platform introduces an anode-less lithium-metal architecture. Enabled by the combination of its superfluidized electrolyte and ceramic separator technologies, the design aims to deliver energy densities ranging from 430 to 470 Wh/kg and volumetric energy densities of up to 1,100 Wh/L. The structure is intended to suppress lithium dendrite formation, one of the principal obstacles preventing widespread adoption of lithium-metal batteries.
Collectively, these technologies demonstrate ProLogium's strategy of balancing battery performance with manufacturability and cost competitiveness. By emphasizing scalable production processes alongside materials innovation, the company aims to accelerate the commercialization of safer and higher-energy solid-state batteries for electric vehicles and other advanced energy storage applications.
