As I have said previously. My information (directly from Boeing) is that the batteries are Lithium-MANGANESE. Where has all this talk about Cobalt come from? Or did I miss something?
According to GS Yuasa's own website, their aircraft battery cells use Lithium Cobalt oxide:

Perhaps, Boeing would not be in its present trouble if it had used SAFT Lithium Manganese oxide cells, which is what AB has done.
