I've had a few people ping me about the statement I made about the MacBook Pro using a Lithium-ion battery. The correction is that the MacBook Pro uses what is called a Lithium polymer battery.

Wikipedia has an nice entry on the differences between Lithium-ion and the more formally known Lithium-ion Polymer battery technologies:

Short form is that the chemistry is roughly the same, but since the electrolyte is held in a solid polymer form rather than a solvent form, a Lithium-ion Polymer battery lends itself to lighter and more flexible designs as well as are less hazardous.

So far I haven't found a good run down on the heat-characteristics of Lithium-ion Polymer versus Lithium-ion batteries, but I did notice that the Apple battery page talks about "Lithium-based" batteries.

If anybody has some good data that they could point us to on this topic, that'd be great.
