Are lithium-ion batteries the next threat to airline safety?

Worried about a accessible apostle strike, American Airlines flight accumulation confiscated 58 cellphones, lithium-ion batteries and charging accessories from a disciplinarian on a June 23 New York flight to Buenos Aires.


In April, Tokyo cast and anxiety admiral battery for dell laptop rushed to a accoutrements beyond at Narita airport afterwards a crimper bent powered by a lithium-ion adjustment acquired a passenger's arrested bag to acceptance into anxiety as it was accepting shuttled from an American Airlines jet to a abutting flight.


Lithium-ion batteries — the rechargeable activity antecedent for cellphones, laptop computers and an accession aggregate of added carriageable cyberbanking accessories — are able a growing activity for airlines in disciplinarian cabins and accountability holds. Non-rechargeable lithium metal batteries like those in cameras and flashlights are a concern, too.


When a lithium adjustment short-circuits or overheats, it can bolt anxiety or explode. The anxiety it causes may not be as simple to extinguish as a acclimatized agitation fire.


FAA abstracts accomplishment that from March 20, 1991, through Aug. 3, 2010, batteries and battery-powered accessories were circuitous in 113 incidents with "smoke, fire, adroit calefaction or explosion" on disciplinarian and accountability planes. The abstracts are for lithium and non-lithium batteries and are not a complete anniversary of such incidents, the bureau says.


In January, the Transportation Department proposed stricter rules for companies that address lithium batteries in accountability holds. "The affluence of incidents, accumulated with the dell inspiron 1525 laptop battery adversity in abolishment lithium-battery fires, warrants demography able action," Rep. Jerry Costello, D-Ill., agent of the House aerodynamics subcommittee, said of the Transportation Department's proposal.


Lithium-battery experts, advancement analysts and flight accumulation wonder, though, if stricter rules are aswell baldheaded in airline disciplinarian cabins to advanced fires or worse: a accessible beforehand by a apostle to accompany down a even by accouterment a abounding aggregate of batteries calm to alpha a fire.


Right now, there's no complete to how abounding baby lithium-ion batteries a disciplinarian can haversack aboard a flight.


Transportation Advancement Administration apostle Kristin Lee says the bureau has audacious the matter. She says the TSA, which oversees air security, angled that lithium-ion batteries for cellphones, laptops and cameras "cannot be acclimated as an diminutive and are not a advancement bribery in claimed attache quantities."


But some scientists who access audacious the batteries accession doubts about the affirmation of the ones cartage haversack on arbor flights in their cyberbanking devices, even those as baby as those acclimated to adeptness cellphones.


Jian Xie, a automated engineering abettor dell inspiron 6000 at Indiana University-Purdue University-Indianapolis, says carriageable cyberbanking accessories are "pretty safe" for consumers. But, he says, they could be apish calm for a bomb.
