The lithium battery problem solved?

hazel · 01-21-2017, 06:54 AM

A team at Stanford University has created a lithium ion battery with its own built-in fire extinguisher. A capsule contains a fire retardant which is released if the battery becomes hot enough to melt its polymer shell. Tests in burning battery liquid showed that the fire was extinguished in less than half a second. http://advances.sciencemag.org/content/3/1/e1601978

I wouldn't say it is a solution. It will/may protect the environment, but will not save the battery itself (not to speak about that: it is irreversible and may cause additional damage). But looks like it is safe for the human being.

"Samsung's probe into its Galaxy Note 7 fiasco has found that the overheating and burning of the phones was caused by defective batteries."

Kind of like a car that can't help but crash into stuff but has a reverse gear when it does??

They could make safer batteries.

Well that will clearly mean to not skimp out on materials. Cost cutting is usually the main contributor for a more dangerous product correct?

My father worked Tool and Die for 50 years. He'd say car companies would have them build 5 or so bumpers or fenders or such. Each one slightly less material than the next. They'd test the part and use the part that seemed to be just able to do the job.

So, yes, cost and someone guessing someplace making a decision as to what will be barely acceptable is the reason. It's never, "we made it to be safe."

Do not try this , leave this to the professional idiots

I think? I read somewhere that the fire retardent in the batteries was highly toxic.
