Hi, Apparently Mills uses LiVO3 as the source of Oxygen in his SunCell, where it combines with H2 to form individual water molecules that catalyze the Hydrino reaction.
This Oxide is also used as cathode material in Li ion batteries (http://www.sciencedirect.com/science/article/pii/S0378775313002401). It's not a great stretch to imagine that it occasionally performs the same function in a battery that it does in the SunCell, leading to a rapid increase in heat energy & temperature due to Hydrino formation, and leading to battery fires.
