Dangerous by design: Runaway miniature battery makes safety testing more accessible and affordable

Runaway battery improves safety

Overheating batteries are a serious risk, in the worst cases leading to fires and explosion. A team has now developed a simple, cost-effective method to test the safety of lithium-ion batteries, which opens up opportunities for research into new and safer batteries for the future. The researchers created an intentionally unstable battery which is more sensitive to changes that could cause overheating. The battery is one-fiftieth the size of conv…

Dangerous by design: Runaway miniature battery makes safety testing more accessible and affordable

Overheating batteries are a serious risk, in the worst cases leading to fires and explosion. A team including researchers from the University of Tokyo has developed a simple, cost-effective method to test the safety of lithium-ion batteries, which opens up opportunities for research into new and safer batteries for the future. The work is published in Nature Energy.

DOBLE LLAVE – Scientists from several countries have managed to identify a phenomenon that breaks with all known paradigms of heat control in the field of electronics and already points to a path that could prevent the heating of devices. A team from the Institute of Materials Science of Madrid (ICMM-CSIC), together with the University of Colorado Boulder (United States) has revealed for the first time a heat transport mechanism that breaks with…

Discovery represents new hope in the search for more powerful and efficient electronic devices.
