All the Li-Ion batteries that have burned have had causes, too. (Faulty
charging circuitry in the main).
I wouldn't expect faulty charging circuitry to be the main cause of
lithium batteries spontaneously catching fire.
Here is the cause of the massive Sony battery recall:

They cite microscopic metal particles that enter the battery
during the manufacturing process as the reason for the battery
failures. The particles, they say, come into contact with other
parts of the battery cell, causing the battery to short-circuit.
Sony claims that these batteries would normally just power off,
but in "rare cases" may overheat and cause flames.
IMHO, that is far more frightening than charging problems!
