New tech could stop batteries from bursting into flames

Stanford University researchers have developed a lithium-ion battery that automatically shuts off before it starts to overheat.

Researchers at Stanford University have developed a lithium-ion battery that could put an end to the headlines that another hoverboard has caught fire.

The battery automatically shuts off before it overheats and restarts once it has cooled down. This kill switch of sorts could help prevent battery fires in laptops, hoverboards, and other electronic devices.

This is the first battery that's been designed to stop and restart over repeated heating and cooling cycles without diminishing performance. Researchers have been trying to find a solution to the accidental fire problem associated with lithium-ion batteries, but none have paid off thus far.

However, principal analyst at the Enderle Group, Rob Enderle, warns that we shouldn't get too excited about the technology just yet. "Until the connection is up and working, you shouldn't take it into consideration when buying a battery this year. It's at least five years out from going to market," he said.
