The Federal Aviation Academy and Boeing have cast new apprehensions over the use of lithium-ion batteries on the Dreamliner's redesigned battery system.
The National Transportation Safety Board has made recommendations over the change and has begun to inspect lithium-ion batteries on Boeing 787 Dreamliners as two batteries on these planes ignited into flames last year.
According to CNN, the safety board said that the FAA needs to revise its 2008 battery standards for all aircraft which remain in effect and they should be subjected to rigorous tests in which cells are intentionally damaged.
Reports have further revealed that such tests can show whether the batteries experience thermal runaway, an uncontrollable increase in temperature and pressure that can cascade or spread to adjacent cells.
