Polymer system suppresses battery fires
GelTech Solutions in the US has launched a modular fire extinguisher system for lithium ion battery packs in vehicles and stationary power systems.

The FireIce Lithium Battery Active Suppression Kit automatically detects elevated temperatures releasing FireIce ST, a special blend of a non-corrosive polymer, to the affected battery module. This cools and suppresses the batteries and prevents the system from reaching runaway which could cause an explosion. The kit is designed to deliver FireIce ST product only to the battery compartment where it is needed, leaving other compartments untouched.

The flexible modular system gives customers the ability to prevent a fire without damaging other batteries or equipment.

After four years of research and development working with multiple lithium battery manufacturers, and companies designing and building units for mass transportation, charging and storage of lithium batteries, GelTech has created a modular system that can be expanded to any size battery installation. The system has the flexibility to be installed in any environment from the typical modular systems in electric vehicles and home power systems, to single batteries like those that have replaced many of the lead acid batteries, in aircraft and ground vehicles.

the kit has been included in bids by several commercial firms and several large lithium battery manufacturers are undergoing evaluations says the company.

The FireIce Lithium Battery Active Suppression kit includes either a 2 litre or a 2.5 gallon pressurized canister filled with FireIce ST, and custom canister sizes are available for larger installations. In addition, the kit includes the hardware, fittings, spray nozzles and flexible hose that allow protection of 5 or 10 modules, respectively. Expansion packs for protection of five additional modules are also available, making the kit adaptable to almost any size installation.

"The message we have received from various industries is clear; with the exponential increase in the use of lithium ion batteries in mass storage systems, central recharging stations and on military and commercial aircraft, comes the need to protect these applications from the potential catastrophic event of a lithium battery fire," said Michael Reger, president of
