Lithium Prevent

Lithium Prevent is a unique, proprietary intumescent, fire resistant, polymer composite technology that is injection moulded to form fire resistant battery pack components that contain the spread of runaway lithium batteries in a wide range of applications.

The product has successfully completed testing programs including internal testing, independent testing, and evaluations at NASA as well as DNV.

Fire Test Standards

  • ASTM E119 – Fire Resistance
  • UL 94 – Flame Spread

Lithium Prevent Features

• A durable polymer composite material• Tailor made formulation
• An injection molded polymer composite• Electrically non-conductive
• Separation between cells segregates
runaway events
• Chemically inertial
• The design allows for the overheated electrolyte solvent to vent out of the package and manage an explosive event• Cost effective
• The pack can be combined with various materials to provide desired mechanical / electrical / thermal properties• Excellent processability
• Chemically inert
