That's the sad story at the beginning of every news article that talks about exploding Samsungs and LGs and iPhones and other smartphones or Lithium-ion battery-powered gadgets. But Stanford researchers have been working on this problem and trying to come up with a way to solve it with the current battery technology that we have. They seem to have succeeded.

Using nanotechnology, they created a flexible film of spiky nickel particles coated with graphene and (an atom-thick layer of carbon).
