The Shorai and Ballistic batteries uses lithium iron phosphate (LiFePO4) chemistry. The Yuasa battery in the Boeing used lithium cobalt oxide (LiCoO2) chemistry. This chemistry has more electrical density than the lithium iron phosphate, but is susceptible the thermal runaway and fire. It is used in cellphones, laptop computers and such. It should not be used in large capacity batteries such as on an airplane or motorcycle. Looks to me that Boeing 787 problem is simply bad LiCoO2 batteries from Yuasa. I would specify batteries from Saft for an airplane.
