Design feature improvements for the battery include the addition of new thermal and electrical insulation materials and other changes. The enhanced production and testing processes include more stringent screening of battery cells prior to battery assembly. Operational improvements focus on tightening of the system's voltage range. A key feature of the new enclosure is that it ensures that no fire can develop in the enclosure or in the battery. Additional details of the new design will be provided by Boeing in the days ahead.Boeing made its certification plan proposal to the FAA in late February.
