Lithium batteries are increasingly used in modern life, both at home and in the workplace. They provide a power source for a wide variety of equipment and unfortunately, due to a variety of reasons including, overheating, overcharging and mechanical damage, can sometimes lead to fires.

Such fires are usually accompanied by Thermal Runaway within cells and Thermal Propagation between cells. To have any chance of arresting both thermal runaway and preventing thermal propagation, high-performance properties are required of an agent.

To prevent or even arrest thermal runaway requires significant cooling action to interrupt the unstable chemical process, and to prevent thermal propagation we must provide a thermal insulation or ‘Fireblock’ between cells.

FIREBLOCK LITHIUM has both properties in abundance, with the capability to arrest thermal runaway and prevent thermal propagation.
