Chuck,  Thanks for this report. Excellent article on this technology problem and how it is being addressed.

It looks like, more than anything, a more robust manufacturing method needs to be defined.

Seems like we have a recurring problem here. I hope the industry gets this sorted out quickly. Do you think these types of findings could require major product recalls? That could be disastrous.

My first question when I saw the Article was "how big of a problem is this?"  This is a multi billion dollar industry that's been around for a while.

From what I understand, Boeing tried to push the technology forward and missed their mark.  I'm surprised to see this issue in the auto industry.

A recall is a possibility, Liz. Mitsubishi has not made an announcement as yet.

The Chevy Volt actually had a problem with a lithium-ion fire, too. In Chevy's case, though, the problem occurred after crash-testing, which is different than this. As to how big of a problem it was, I specifically asked Donald Sadoway of MIT, who is one of the world's foremost battery experts and founder of a grid storage battery company called Ambri, whether the media was making a big deal out of a small story. His full response: "The press is right to call attention to the precarious nature of Li-ion technology. It's one thing to have a fire in a plant. It's another to have a fire in a plane at 40,000 feet. Remember, Li-ion technology is 20 years old now. Shouldn't we have worked out the bugs by now?"

It seems the that current lithium-ion technology has to find a safe, reliable way to counteract the energetic and rapid discharge nature of these batteries before wide-spread adoption should truly be deployed.

 

Is there another battery technology appearing on the horizon soon that is safer than lithium-ion?

@Greg: Lithium Batteries always had this issue and it happened to something else sometime back. I simply cannot see why they did not see it coming their way after knowing the impacts

Air or liquid cooled?

Was this battery air-cooled like the Nissan Leaf and Boeing, or liquid cooled like the Volt and the new Ford PHEV and EVs?

Charles, you should know better than to brought the Volt fire up . . . that fire had NOTHING to do with the lithium ion battery.  It was the coolant surrounding the battery that leaked on a circuit board that caused the short circuit.  It was NOT the Li battery. 

Shame on you, Charles . . .
