*'No fire risk' with new lithium batteries*
Lithium-ion batteries that are resistant to exploding or igniting have been developed by scientists in the US. The devices produced sufficient energy for use in household electronics, but did not catch fire or explode - even when punctured repeatedly with a nail.
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).
The latest paper follows on from a 2015 publication in Science journal, in which the same team unveiled a similar 3.0 volt battery with an aqueous electrolyte. By coating the anode with the protective gel polymer, the scientists were able to push the battery voltage up to 4.0, making it useful for household electronic devices such as laptop computer.
