Officials are looking into the safety of lithium ion batteries for Boeing 787 Dreamliners after a fire broke out on a parked Japan Airlines aircraft in Boston on Jan. 7, and crew and passengers smelled smoke on a All Nippon Airways flight on Jan. 16.

Lithium-ion batteries are known to overheat and ignite when they are damaged, improperly charged or discharged. Officials are looking into implementing potential safeguards for the batteries, including enhancing the batteries' containment box, installing heating sensors, increasing the space between the internal cells, and stabilizing the cells within the container to prevent unwanted movement.

According to Reuters, "The 50 Dreamliners in service were grounded worldwide on January 16, after a series of battery incidents, including a fire on board a parked 787 in Boston and an in-flight problem on another plane in Japan. The groundings have cost airlines tens of millions of dollars, with no end in sight."
