New Stanford University developed battery shuts down at high temperatures and restarts when it cools.
Stanford researchers have developed the first lithium-ion battery that shuts down before overheating, then restarts immediately when the temperature cools.
The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from recliners and computers to navigation systems and hoverboards.
“People have tried different strategies to solve the problem of accidental fires in lithium-ion batteries,” said Zhenan Bao, a professor of chemical engineering at Stanford. “We”ve designed the first battery that can be shut down and revived over repeated heating and cooling cycles without compromising performance.”
