Why you shouldn't mess with lithium ion
 

Why you shouldn't mess with lithium ion un less you really know what your doing. (and even then)

Lol.

And this... is yet another reason that Lithium Iron Phosphates are greatly favored over older lithium chemistries for vehicles.

... far less prone to burny doom.


... Then again? Same situation with gasoline? O.O...

Except this is a brad new state of the art vehicle using lithium ion phosphate batteries.

Then again gasoline doesn't set itself off

A proper battery management system should prevent this from happening, I was at a presentation by the University Of Minnesota Solar Race team and they told us about their battery management system that kept track of the voltage of each cell in the pack and cell temp and if the voltage or temp went out of spec for even a second it would shut the whole pack down requiring a manual reset, but part of the battery management system also was to keep the voltage from going out of spec and if any part of the monitoring system failed it would also shut the battery pack down.
Of course they were doing this more so to preserve the packs ability to hold a proper charge then to prevent it from starting on fire, because the battery chemistry that they were using was supposed to be thermally stable, the batteries that are not release oxygen when they over heat, then they start on fire and don't want to stop burning.

Lol. Well I do suppose I should have noted they make it HARDER to pull off burny doom... not impossible. XD


Neither do lithium cells unless quite severely flawed. It takes electrical, thermal, and/or physical "abuse". Less than gasoline? Decent quality LiPE I could see arguing being on even ground plus or minus developed safety systems and standards. Other lithium chemistry... ok yeah. Bad quality cells? Duh. Their thresholds are a bit. Low.

Though. I suppose low quality gasoline isn't more likely to 'asplode(if anything in fact, I'd assume it would be less so XD). A low quality fuel handling system however... Well. Look up car recalls for the last 20-30 years. Electrical shorts in in-tank fuel systems in particular...
In contrast, poorly manufactured batteries are VASTLY more likely to fail, and fail spectacularly. This is especially terrible on classical lithium cells (I'm glaring at you Sony! Metal contaminants... really...). And just like gas, poorly managed... Well. You get the pattern.

My wife drove home last night and told me the car was smoking. When I popped the hood it blazed up. Sometimes cars catch fire... I'm not blaming gas for causing it. Anyone want a toasty dodge stratus?

XD Gasoline don't cause it. But its properties of hanging near the ground in gaseous form certainly does make it easy with ANY external cause combined with a leak. (Rather than say, hydrogen or propane. Which float upward. Especially hydrogen. Or say lithium batteries... which have no gaseous form. Well. No commonly observed one... *thinks about uses for thermite*)

... XD Does it still drive?... No? damn.

Lithium ion | = lithium iron |= lithium manganese |= lithium polymer |= lithium air

There are many different formulations of lithium batteries even within these groups and they are all different properties.

Ok, but what about the safety of dilithium crystals?

If you're not careful, this could happen.
