@g_ost: Well yes there are uncertainties but I feel we should give it some time before coming into a conclusion. Who knows things can change.

@Cabe: Im not saying they trust it over others but it has  definite edge over some of the most well-known ones.

A.Saji,

You are saying that they trust this battery over others, even after some set of fire?

I suppose larger companies do have the resources to make a battery with more features and safety measures built in.

@Shehan: Yes indeed but many don't do it. Some do it but does not cover all areas. That is why many projects fail in the middle.

GTO-L

Spot on there.. a future of things to come.

Now that the problems are worked out... the unit sure has gained in popularity. Anyone can build a battery pack, so why stick with this...

I'm a little less bothered by the choice of lithium-ion for the ISS than I was by the choice of it for the Boeing 787. Still, as many readers have pointed out here, it's a very risky decision. Is the energy density really that critical? Is it that much more important to have 150 Wh/kg, as opposed to 100?

shehan, solar panels are used on some satellites, but the power generated by those panels must be stored somewhere, and that requires batteries. Some satellites operate on batteries without solar panels. Does that answer your question?

I, too, won't pretend to be an Aircraft or Spacecraft armchair engineer.  But, as an engineer with almost 35 years of practical experience, I'm quite shure when I see an "engineering goof", like the one made by Boeing (and probably by NASA too!).  when the pursue  of technology for technology, without regard or concern about others, has produced many technological centered accidents.  As engineers, we all should work to advance the state of the art.  But not risking other's lives (just picture a 787 suffering a battery fire in the middle of an ocean crossing!) or the ISS damaged because one Lithum battery decided to make an act...

Most of us seem to agree that technology advancement won't be compromised if we are careful and do not rush in an innovation race.

Again, as professionals of Engineering, we must be careful and responsible.  Our main duty is to produce safe, reliable designs.  Those engineers working in fields more tolerant about possible failures can play a little and adventure in newer technology applications; but those that deal with others life and wellbeing, need to forget about playing innovation and play it safe.-

Best Wishes. Amclaussen.

I won't pretend to armchair engineer about a field I know little about. I was just a bit surprised at all the calls to just abandon the technology. I'm sure Li-ion battery tech has a place somewhere, and in due time (and effort) can be made much safer. Maybe the time is not now, but if everone abandons the work on it then how will the issues be solved?

That is definitely NOT my case; I have worked with Lithium batteries since years ago, and my impression has not been changed by the recent news, it became REINFORCED.

Now, given the abundant, detailed and quite neutral information published here by our dear fellow Charles Murray on the B-787 matters, it is hardly valid to believe that conclusions here are 'mostly emotional'.  As Tekochip has painfully confirmed, Lithium batteries are a different kind of animal, even in several variations of the chemistry and electrolyte, Lithiums have been producing overheating and fires in MANY cases.  We are in front of a real problem, not an imagined one.  As an engineer, given the choice, I prefer to err on the safe side.
