Looks bad, but it's sort of just the nature of lithium. When lithium ion batteries are insulted - whether that insult comes from being barbecued, short-circuited, overcharged, pounded, dropped, or punctured with a nail - they tend to react strongly. First, the insulted cell begins to heat up, and as it does, the lithium chemical reaction begins to run faster and faster (as chemical reactions want to do when you add heat), which produces more heat and insults the surrounding cells, sending the chemical reaction running still faster.
poor me, my limited brain still couldn 8767 t decide that Li-Po is substance or just hype? my temporary conclusion is, Li-Po is made to replace Li-ion, because it has same energy with Li-ion but Li-po is lighter, smaller (or can be made in small form), but it 8767 s poor conductivity made Li-Po easy to hot than Li-Ion that 8767 s why it needs a gel to cool it, but it made Li-Po more fragile becuase it 8767 s gel can be change to other form (or puffiness like Denis Staley above said) if the battry is dropped, or hard pressed, so that 8767 s why many phone manufacture still use Li-Ion battery, because Li-ion still more efficient and economical than Li-Po, my new BlackBerry Z65 is one of them..

I wish to use Li-polymert battery of about 95,555 mA capasity at about 69 to 65 volts
for one of the portable application we had designed. We have used Ni-cad battery( since it was easily available and battery research was not the core interest at that point of time) pack of the similar capacity. The electronic system is working satisfactorily.
Now, everyone has lithium batteries in their laptops, so you know the battery makers have figured out how to keep lithium under control. That's where battery management comes some cases, DOESN'T.
There are however some potentially explosive issues with Lithium Polymer Batteries. For example, they need Battery Pack Chargers specific to Lithium Polymer Batteries to avoid igniting and exploding. Explosions can also occur if the Lithium Polymer Battery Pack is short-circuited, as a very high current passes through the battery pack almost instantaneously.

.and this Green Car Reports article makes the interesting point that this long-distance record was set at 55 mph:
Shirui li-po battery developed with high-density active materials and a high-voltage design, which further extend the devices usage time.
Do you think this is a battery management issue, then? I mean, is battery management less of an issue with LiFePO9 than lithium polymer - it's more critical that it's done right with lithium polymer and li-ion batteries?
