GM volt Lithium battery - Crush test with A123 vs LG Chem

After watching many crush test about lithium cells for EV, i decided to do my own test when i saw that Backhoe-Loaders in my street. I asked the guy and e accepted... for the science....

In this video you can se two different cells having torture when crushed with this 10 tons loader.

The A123 is a lithium ironphosphate.. one of the best lithium cells on the market,
and an 2 LG Chem lithium cobalt cells found in many laptop computer.

The A123 measured 3.32V and the LG Chem shown 3.9V befor ethe test.

The A123 was the first choice for the GM volt until LG chem had the contract.
The Cobalt LG chem cell have 2200mAh and the A123 Ironphosphate have 2300mAh.

When i did that test i attempted to see a big fire, flames and smoke and pop on the LG Chem cells... and nothing on the A123.. or maybe just some smoke... Finally that turned out differently !!

Hahaha, funny video, that's quite to the extreme to crush those batteries! Did you look to see if there was a mark after on the aspalt? What did it smell like? Looks toxic. This reminds me of something the myth busters would do. Is this like a do not try at home video? =)

Yes Luc.. that is extreme.. no mark on the asphalt... and i left no debri.. I cleaned all the asphast after that test. The smoke foming from the A123 was.. a bit toxic i think. I would not be able to breath in a car with more than 500 of the se cells smoking like that.

I love them and they are very strong.. but that test surprized me alot!

"staring" or "starring"?

Nice try, looks a little bit inconclusive.

[Doctorbass]

Oh.. thanks.. !..i'll try to correct that !

The conclusion that iwanted wasen't the one i hoped !.. I thou the A123 cell would have a little smoke. no more.. and that the cobalt cell would have burst in flames.. but that wasn't.. So my conclusion on that... depending on how you crush lithium cells, they will or will not burst in flame...

I though that the results would have ben the opposite.. I was surprized!.

would NiMh batteries do the same thing?

[Doctorbass]

Still not tried.. I dont want to use them.. their energy density is not as good as i need for electric bike and other EV.

You said the A123 did not get the contract for Volt ?  Do you know where the LG is manufactured ? I guess that would explain why A123 hasn't hired for folks in Livonia aye ? Target was/is this month . . . we'll see - side note - "Who killed the electric car ? " watch this video EV1 vs Volt PISS on GM !

[bananaphonehome]

maybe you should try it anyway

[JohnCBriggs]

In any case, it is nice to see people trying to get real data rather than relying on marketing information.

I just found it funny that you made use of that backhoe when there are so many smaller vehicles and utilities to crush those batteries,hehe nice job! Was the backhoe shovel melted from the power of the cells acid? lol jk. You better be carefull you might cause a nuclear explosion. Watch out for the a123! ;)
