The Apprentice:Lithium fires are horrendous in that you cannot tackle them with anything wet as it just makes burn more.
Quite true....when working with SOME cell chemistries. I'm getting increasingly annoyed with the lack of coverage of battery technology - the automotive press has a duty to get more educated about the various chemistries that are being developed.
Referring to 'lithium batteries' is like talking about a car that take fuel in 'liquid form' - it could be LPG, gasoline, diesel, bioethanol, hydrogen etc.... Lithium is a catch-all and isn't specific enough to make any statement about. There are a number of companies - of which one in the USA called Valence Technology is the leader in terms of units distributed - developing batteries that use SAFE and reliable lithium iron phosphate chemistries (and in the future lithium iron vanadium phosphate).
Volatile temperatures for lithium cobalt chemistries, such as those used in most laptops etc., are about 150-degrees. For these new, safer chemistries, it's about 800-degrees.
