AI Technical Summary
Technical Problem
Secondary batteries are vulnerable to thermal runaway due to internal defects or external impacts, leading to rapid energy release and fires, which conventional fire extinguishing methods fail to prevent or effectively suppress.
Method used
A fire suppression extinguishing sheet containing a fire extinguishing liquid with a catalyst to block oxygen reactions, digestible substances like carbonates to decompose and neutralize flammable gases, and surfactants to prevent aggregation, integrated into a storage pouch.
Benefits of technology
The solution effectively suppresses and extinguishes fires in secondary batteries by blocking oxygen reactions, neutralizing flammable gases, and preventing the spread of flames, providing time for evacuation.
