Pete,
The Dreamliner problem was not the battery itself but the battery charging unit.
Overcharged it causing cells to overheat and runner away. They did increase
the space between cells but the main remedy was to build circuitry that
controlled
the charging. They enclosed it with a vent overboard because the fumes were
very nasty!
Cheers,
TIM
