Core Competencies & Industry Advantages

Revolutionary Fire Suppression Technology

Lianjie's flagship lithium battery fire extinguishing agents utilize a penetration and inerting mechanism, addressing the unique challenges of lithium battery thermal runaway. Unlike traditional fire suppressants that focus on oxygen deprivation, our technology penetrates deep into battery cells, rapidly cooling internal reactions and neutralizing flammable gases. This approach not only extinguishes flames within seconds but also eliminates re-ignition risks, a critical advantage over conventional methods
