ProLogium Demolishes Solid-State Battery Safety Fallacy through Innovative Dual Safety Measures
In a significant development for the lithium battery industry, ProLogium's fourth-generation superfluidized all inorganic solid-state lithium battery promises improved safety through multiple key advancements.
High-temperature simulation tests have revealed that sulfide solid-state electrolytes can transform into internal lithium-based explosives under heat, triggering thermal chain reactions and causing potential explosions. However, ProLogium's battery platform, with its intrinsically non-combustible materials and active thermal risk control, marks a new benchmark in lithium battery safety.
The root cause of lithium battery thermal runaway is the inherent reactivity of the electrodes under high temperatures. ProLogium's battery addresses this issue with an innovative approach that redefines safety. The battery uses a proprietary superfluidized fully inorganic solid-state electrolyte embedded with an Active Safety Mechanism (ASM) material. This mechanism proactively interrupts hazardous chemical reactions at critical temperatures, preventing thermal runaway and ensuring the reaction chain does not propagate, even in high-energy cathode/anode configurations.
Another critical component of ProLogium's battery is the oxide-based all-ceramic separator. This separator, in mass production since 2013, maintains structural stability and electrical insulation at high temperatures, effectively blocking dendrite penetration and preventing thermal propagation inside the battery.
The battery also exhibits unprecedented thermal stability. Accelerating Rate Calorimetry (ARC) tests confirmed the battery does not exhibit thermal runaway, no spontaneous heat peaks, and significantly reduced total exothermic energy. This shows a reversal of the traditional ignition-to-end thermal reaction chain seen in conventional lithium batteries.
ProLogium’s approach redefines safety by combining material chemistry innovations with system-level structural designs. This shift from passive containment of hazards to proactive risk elimination and control ensures the battery system physically stabilizes battery components at high temperatures, chemically interrupts hazardous reactions, and prevents thermal runaway rather than merely containing it.
Furthermore, the electrolyte in ProLogium's battery achieves a world record ionic conductivity of 57 mS/cm at room temperature—5 to 6 times higher than traditional liquid electrolytes. This high ionic conductivity enables fast charging without safety trade-offs, contributing to operational stability and reliability.
In conclusion, ProLogium's fourth-generation superfluidized all inorganic solid-state lithium battery represents a significant leap forward in lithium battery safety. By addressing the inherent reactivity of electrodes under high temperatures, ProLogium's battery offers a promising solution to the safety issues that have long plagued the lithium battery industry.
