Report: Elon Musk ready to help Boeing with 787 Dreamliner lithium-ion battery problems

NTSB said themal runaway uncontrolled chemical reactions within the batteries cells surprise surprise, and short circuiting were present in the investigation. http://www.ntsb.gov/investigations/2013/boeing_787/JAL_B-787_1-24-13.pdf I think that the Boeing 787 APU battery take a real pounding and has to provide a lot of extra grunt to the electric starter/generators to get them turning start the APU & Engines that have their own starter/generators. Apparently the voltage is stepped up for the APU thru inverter and transformer/rectifier, the whole concept relies on the Lithium cell and it's properties and so Ni-Cad won't get a look in. A traditional nicad battery is used on other types of aircraft APU's and could not do or cope with the starting of a 787 which is designed without a traditional smaller APU electric starter/pneumatic system that then spins the engines over wit...
