Boeing has announced improvements to the lithium-ion batteries for its 787 Dreamliner. A series of modifications to the batteries and their casings were made in response to battery fires in mid-January aboard two 787s in Boston and over Japan that resulted in all 50 of the planes delivered to customers being grounded. According to a company press release, the modifications along with improved testing regimes should prevent a repeat of the incidents.
