Making lithium-ion
battery systems safer.
Product Description
LithiumPrevent is a passive fire containment solution that makes lithium-ion battery systems safer by preventing thermal runaway propagation. Including LithiumPrevent in the design of an OEM’s battery system is proven to achieve the industry’s toughest fire safety test standards. The base material is a proprietary intumescing polymer that can be extruded or injection molded to meet application requirements.
LithiumPrevent provides fire safety solutions for problems associated with lithium-ion batteries:
• Contains thermal runaway at the cell or module level
• Provides thermal separation between cells or modules
• Controls explosive events
• Prevents cascading fire propagation
• Prevents transfer of internal heat to outside combustibles
Lithium Prevent Features
• A durable polymer composite material
• Can be injection molded or overmolded to almost any shape or size
• Extrudable into sheets for various applications
• Several commercially available formulations
• Electrically non-conductive
• Separation between cells or modules segregates runaway events
• Designed to manage an explosive event by venting both ejecta and gases
• Several commercially available formulations
• Excellent processability
