Airbus have stated (Very publicly) that they are reverting to NiCd on the A350, general perception appears to be that Lithium batteries and aircraft are a bad combination.
With the 787 production line still going, this suggests that whatever the solution is, it will be constrained by having to fit within the existing battery bay.
Not sure that I wouldn't have preferred a blue-sky solution where ultimate safety was the only constraint.
