Samsung Galaxy Note 7’s are exploding when they are charged. The tech media is, rightly, trying to get to the bottom of
this.
Much has been said about how this can happen and the focus
appears to be on overcharging Li-ion batteries and the resulting heat
generation. The only party that actually
knows something about this is Samsung and they have said that there was a “minor
flaw in the battery manufacturing process”.
This does NOT sound like an overcharging problem. This could be either misalignment of
electrodes leading to lithium plating and shorting. Or something like copper dissolution and subsequent
deposition leading to shorts.
Or something else.
But more importantly, except for Samsung, we are all
guessing. As long as Samsung does not tell
us (and I’ll go on a limb and say that they will not), we can make up anything
we want. But guess what: we are making
stuff up! We should probably stop.
But where is the fun in that. So let the speculation continue.
Interestingly, the Chinese made batteries by ATL are not
exploding. Only the Samsung made ones
are. So much for "low quality Chinese manufacturing"…
