Test day extinguishing battery fires: is sodium silicate the solution?
Fires in Li-ion batteries in electrical vehicles are difficult to put out. The recommendation is to cool the battery to its core, using large quantities of water. However, after a short time, the fire often flares back up. In collaboration with ARN, collector of old batteries Van Peperzeel has developed sodium silicate as a possible new extinguishing agent for fighting battery fires. Peter Butter of the Amsterdam-Amstelland safety region tested the new agent at Troned, on 10 September. The results were astonishing.
Butter organised the test day in conjunction with ARN, Van Peperzeel and Record Brandbeveiliging. The Li-ion batteries supplied by ARN for the practical tests were no longer live. “These are old rejected batteries that can no longer be recharged or used for other purposes, making them ideal for the tests,” explained Marlies Meijer-Willems of ARN.
