Japan Grounds Fleet of Boeing 787s After Emergency Landing 180
hcs_$reboot writes "The Boeing 787 Dreamliner has already occupied some of Slashdot news space recently: FAA to investigate the 787 (Jan 11) or 787 catches fire in Boston (Jan 08). Today (Jan 16 JST) another incident happened that led to Japan grounding its entire 787 fleet until an internal investigation gives more information about the problem. A 787 from ANA had a battery problem and smoke was detected in the electronics. The plane had to make an emergency landing and passengers were evacuated. "

Boeing had to get the FAA to waive its rules regarding Lithium batteries [avherald.com] on planes in order to get this plane certified in the first place, and build containment boxes for the batteries into the design.
For the most part the risk of Lithium batteries lies in the requirement for rigid control of recharging, being careful not to over charge and also of draining the battery completely, the annoying habit of catching fire when the rules are not followed, or when the battery is short-circuited make large Li batteries (8-gram equivalent lithium content or more) banned in luggage, and shipments.

You're the first person on this entire thread to hit the nail on the head. The Dreamliner uses a sophisticated network of computers and sensors to fly. If all the engines fail, power must be supplied from the APU, basically a UPS for airplanes. Because of the amount of electronics and the fact that due to a lack of power the hydraulics and other critical systems must also remain powered... there is a massive power need. The APU is designed to power the aircraft's systems in the event of an all engine failure from cruising altitude all the way to landing; Although the more common scenario is that an electrical fault causes fuses, etc., to blow, and the APU is switched on (an isolated power source) so the plane can land safely.

For aircraft, the real reason is lithium + aluminum leads to rapid oxidation of the aluminum. Basically a small blob of lithium in contact with aluminum will eat a hole in the aluminum. That's why there's lithium restrictions. The containment vessel has to be made of another metal (steel, normally) so that the lithium will not come into contact with any aluminum structure.
Re:This can't be true (Score:5, Interesting)
No, that's not why.
The reason is that lithium fires happen fairly easily, and the fire extinguishing systems aboard aircraft are not all that effective against such fires.
Several FAA bulletins have reported that "The current fire suppression agent, Halon 1301, found in class C cargo compartments is inefficient in controlling a lithium metal cell fire." Yet halon is just about all they have on board other than water.
See Slide 7: http://www.777cheatsheets.com/resources/Lithium_Battery.pdf [777cheatsheets.com]
See Page 9: http://www.fire.tc.faa.gov/pdf/04-26.pdf [faa.gov]
Tests were conducted using 4, 8, 16, and 32 CR2 batteries, the 10.75 fire pan, and 220 ml of
1-propanol. In each case, the results were identical. Discharging the halon prior to battery
ignition resulted in the extinguishment of the 1-propanol fire and no battery involvement.
However, discharging the halon after only one battery was ignited had no effect on stopping the
propagation of the battery fire to adjacent batteries. The halon extinguished the 1-propanol fire
immediately but had no effect on the lithium fire with the exception of turning the normally
white sparks bright red.
The color change of the lithium sparks indicated that a reaction was occurring between the
lithium and the Halon 1301. This reaction had no effect on the fire progression, neither
hindering nor promoting the spread of the battery fire. The vented electrolyte fires, normally
pale red in color, turned bright red when exposed to Halon 1301.

Not all lithium batteries are equal. Lithium Iron Phosphate batteries for example are reasonably safe. You can over charge them, put a nail through them plus they last 10 years, but they don't have as high an energy density as found in cobalt based cells which are more typically used in laptops and cellphones.

I did some consulting for a small aero engines company about 15 years ago that had a brilliant concept dreamed up by a non-technical MBA executive to start building aero engines for small aircraft based on race car engines. Reasoning for that is because they are high performance engines. Well d'ohhh that is not what you want in an aero engine, you want reliability & safety as the most important factors. Race car engines need to be rebuilt after every race. Not a desirable attribute for an aero engine.
