Lithium Metal Batteries (DuraLite)

[Mike Hester]

Yep sparkly and radiant light.

However you totally ignored the fact that LITHIUM ION cells vent flame if overcharged. It is NOT totally safe!!!!

I am NOT talking about lithium metal, the original duralites. I am talking about a product out there being sold right NOW!!

I'm not debating the chemistry either. All I am doing is warning. 

They say a picture is worth a thousand words. Well type in this link and here's a few thousand from me.

When you walk through your friend's house and it looks like that....

And that my friends is why I have a HUGE aversion to LITHIUM ION batteries, specifically the round cell type. 

Now enjoy the pics, and the warnings? Take it or leave it. I can sleep now.

  The problem with the Duralites is they use Lithium metal for the anode.  The reason Erickson rejected them was due to safety problems.  Li-Ion is not in the same category and should not be confused with a cell that uses lithium metal for the anode.  The problem with using lithium metal for the anode is that after several charges the morporology of the surface is quite different in fact dendrites (potential shorts with high temperature) can be formed on the surface of the lithium.  In the case of the lithium-ion the lithium is intercalated into graphite and is readily moved back in upon charging.  the reason charge control is critical (no overcharging) is to control the plating of lithium metal in the cell.  I hope that this sheds light on the subject.
