This product not only has such excellent freeze resistance, but also has flame resistance. Due to these characteristics, when used for mobility, it is a technology that can not only suppress the ignition of battery cells, but also fundamentally suppress the spread of fire to the entire pack or electric vehicle even if a fire occurs in an individual cell. Unlike solid-state batteries that still have a long way to mass-produce, this technology consists of general materials that are currently in use. Therefore, it can be mass-produced quickly to protect people's safety.
