‘No Fire Risk’ With New Lithium Batteries

Lithium-ion batteries that are resistant to exploding or catching fire have been developed by scientists. From a report: The devices produced sufficient energy for use in household electronics, but did not ignite — even when punctured repeatedly with a nail. The batteries use a water-salt solution as their electrolyte, removing the risks carried by some non-aqueous commercial models. The research is published in the journal Joule. “In the past, if you wanted high energy, you would choose a non-aqueous lithium-ion battery, but you would have to compromise on safety. If you preferred safety, you could use an aqueous battery such as nickel/metal hydride, but you would have to settle for lower energy,” said co-author Kang Xu, from the US Army Research Laboratory (ARL). “Now, we are showing that you can simultaneously have access to both high energy and high safety.”
