Lithium-based batteries such as those with electric power vehicles at risk of being

Batteries enhanced by a polymer material releasing chemicals that prevent chemicals at high temperatures less likely to explode in flames. This technique can increase the safety of battery machines, such as electrical vehicles and medical devices.
“Our method enhances the safety within the mainstream liquid loquium battery,” as Ying Zhang At the Institute of Chemistry, Chinese Academy of Science. “It’s like popping to open a safe valve – these chemicals that burn burned gas before they can get off, helping prevent fires.”
Zhang and his colleagues do and try the burning polymer polymer in a prototype lithium metal battery. Such batteries are currently in limited use, but the versions of the consecutive candidates are replacing batteries in electrical cars and portable electronic devices. That is because lithium metal can store 10 times a lot of energy as famous lithium-ion batteries by using pure lithium, rather than graphically, in negative electrode.
Researchers unfolds the prototype battery and a standard battery of metal-yum-slowly warm temperatures, starting from 50 ° C. If the two-sized prototype materials have begun to withdraw the “microscopic extinguishers”, says Zhang.
More than 120 ° C, the standard battery with no safety features overlooked by 1000 ° C within 13 minutes and blasting of flame. But under the same conditions, the battery temperature of the battery is reached only at 220 ° C, with no fire result or explosion.
This “new science method” can reduce the risk of Battery fires or repair, not only with lithium metal batteries but also some lithium-ion batteries and lithium-sulfur batteries, as Jagjit Nanda In the Slac National Elecerator Laboratory in California. This can lead to safe batteries, especially for electric cars or even Electric Aircrafthe said.
Technology prevents fire will be carefully involved in the existing battery production as a “industry-involvement of the battery’s long-term solutions and chemistically, injecting material polymer to batteries will require some withdrawals Manufacturing process, he said.
