FAA Proposes Ban on Lithium-Ion Batteries in Checked-In Luggage

Gizmodo reports here on a proposal by the FAA to ban devices with lithium-ion batteries in checked-in luggage. They would like to see such a ban to be worldwide.  Their concern is based upon a test in which a lithium-ion battery caught fire next to a bottle of dry shampoo; the resulting fire was too fierce to be contained by aircraft fire suppression systems.
