My friend's PC in water cooled, every component. If that slacker can do it, I don't see why Boeing can't do the same.

Yes, Gorksi, it's a matter of liquid versus air cooling. It's also a matter of passive versus active cooling. As far as we can tell, Boeing is using passive air cooling. There reportedly are no fans to draw the hot air away. Toyota uses air cooling on its Prius PHV, but it is active air cooling -- they use three fans to draw the heat away from the battery's cells.

787 batteries need liquid cooling

The solution seems to be liquid vs. air cooling. The article states that air is less dense at higher altitudes and is less efficient in cooling anything even though it's at a lower temperature. Volt has gone to liquid cooling that works. What is Boeing waiting for? Call the GM engineers and find out what they did. A Volt did go on fire a little while ago.

As far as I know, naperlou, the only reason to use lithium-ion is the energy density. Higher energy density means they can cut weight, which is of course always important in aircraft design.

Chuck, is there any reason they just don't go back to a known battery technology?

Check out these strange technology acquisitions. Many of these mergers became burdens the companies couldn't bear.
The Strati EV car printed at IMTS is made of SABIC's LNP STAT KON AE003. SABIC tells Design News why this carbon fiber-reinforced compound was chosen by Local Motors and Oak Ridge National Laboratories.
The 2014 Ig Nobel Prize in Physics was awarded to Dr. Kiyoshi Mabuchi and his team members for their work measuring the slipperiness of banana peels. Turns out they're slipperier with the yellow side up.
Many scientists have been working battery-free ways to power wearable electronics that can replace bulky battery packs, particularly through the use of energy-harvesting materials. Now a team of researchers in China have upped the game by developing a lightweight and flexible solar cell that can be woven into two-way energy-harvesting fabric.
Researchers in Canada have developed a chin strap that harvests energy from chewing and can potentially power a digital earplug that can provide both protection and communication capabilities.
