Default Why the Galaxy Note 7 Caught Fire?

Footnote: When batteries are charged and discharged, chemical processes cause the lithium to migrate and the battery will mechanically swell. Any battery engineer will tell you that it’s necessary to leave some percentage of ceiling above the battery, 10% is a rough rule-of-thumb, and over time the battery will expand into that space. Our two-month old unit had no ceiling: the battery and adhesive was 5.2 mm thick, resting in a 5.2 mm deep pocket. There should have been a 0.5 mm ceiling. This is what mechanical engineers call line-to-line -- and since it breaks such a basic rule, it must have been intentional. It is even possible that our unit was under pressure when we opened it.

But - they were space efficient!

Obviously the chem engineers and the mechanical ones didn't get together on this one!
