On Tuesday, the FAA approved Boeing's redesign of the internal batteries that powered the aviation company's 50-plane 787 Dreamliner fleet. Boeing still needs to rigorously test the new battery design before the FAA will allow the planes to fly again, but this approval is a first step toward that.
Two of the Dreamliner planes caught fire in January of this year, leading the FAA to ground the entire fleet. One academic called the original battery design “inherently unsafe” because of the lithium-cobalt oxide cathode used to power the planes—essentially a bigger version of what's found in a common laptop or cellphone.
In February, the National Transportation Safety Board confirmed that the two planes caught fire due to short circuiting in an individual cell, leading to thermal runaway causing the other cells to catch fire.
