They're putting Li-Ion batteries in cars! Are they nuts?!

At first I thought it was just the random person ... Now it seems there are lots of folks trying to soup up Hybrid electric cars with Lithium-Ion batteries! Are they nuts?! Li-Ion can be very very unstable and dangerous. Deform or puncture one and you'll have a very quick flash of fire and explosion.

You probably aren't going to throw around and mutilate your laptop so it's okay in there, but putting it in a car is just asking for trouble. Car's mean potential for accidents, which means potential for battery getting deformed, which means a big kabooom. And you can only wonder about adding gasoline to that situation. There is a reason no sane car manufacturer puts Li-Ion batteries in cars. Hybrid cars use NiMH batteries for a reason. So is the case with the more than a century old Lead Acid battery still used in normal cars.

Putting your own life in danger is one thing but driving around with what amounts to essentially a bomb and putting others' life in danger is totally irresponsible and should be against the law. Please do us all a favour and put a big sign saying "Li-Ion powered car" so I can stay far away from such things. Since most of these are being done on existing hybrid cars, I'm going to be wary of driving around one from now on. Especially Toyota Priuses.

Edit: There are safe versions of Li-Ion batteries in development but it doesn't look like its being used in some of these souped up hybrids being reported.

That is certainly true of current-generation Li-ion batteries, but there are apparently advances in the technology which makes it more attractive.

See http://www.wired.com/news/technology/0,1282,68631,00.html for example.

Ah yes. I've heard of Valence and Saphion and I wouldn't have any problems with those being used. However it doesn't look like any of those DIY tinkerers are using that. But thanks for the link. Now I can put up links to some pictures about how dangerous Li-Ion can be.

No worries :-)

I had a look at the link you posted, and you're right: it looks like they're just using normal Li-ion. Luckily there's only "about two dozen" in use - the chances of you actually crashing into one is pretty low! Lets hope they get their act together before it become more popular.

Uhm, you know what *normal* cars run on? I think there might be a bit of a fire hazard involved in that as well...

Sigh ... Actually gasoline/petrol is much safer than Lithium-Ion. It takes much more to ignite it and sustain a fire. Mythbusters on Discovery Channel conducted an experiment in which they shot at a fuel tank with various kinds of guns including tracer bullets (such bullets leave a trail of light/fire behind them). They could not explode the fuel tank or even cause a fire. On the other hand shooting a bullet into a Lithium-Ion battery will most certainly cause a fire (see the wired.com photos I've linked to). The simple reason is chemistry. Li-Ion batteries come readily packed with an oxidising source (oxygen) within them (LiCoO2). Whereas gasoline/petrol requires the relatively less readily available Oxygen in air. Li-Ion burns very fast and violently. Its not easy to put out such a fire. I'm not saying gasoline/petrol is totally safe. But compared to Li-Ion its the difference between firecracker material and TNT.

Fianlly there is a century of experience handling gasoline/petrol and making it safe enough for transportation use. There is very little for Li-Ion.

My brother-in-law is one of "those people" -- actually, he's been hired by an electric car company that's using stock Li-Ion cells.  There's a boatload of research going in to making the crashes as safe as possible.  It's not just altruism, either: they can't sell the car until it's passed the crash tests without exploding.
