BUNCKER®
Advanced thermal runaway packaging for lithium batteries
Lithium-ion batteries power modern industry, but their high energy density comes with a critical safety risk: thermal runaway. During a thermal runaway event, a lithium battery can generate extreme heat, flames and hazardous gases that traditional fire suppression systems may not be able to control. Safe lithium battery transport, storage and handling therefore require specialized safety solutions.
