手机党:新型电池充电仅需1分钟

The battery that can charge your mobile in just ONE minute
新型铝电池充满电仅需1分钟

手机已经成为当今社会每个人的必需品,而你是不是苦恼每天一充的尴尬呢?充电仅需一分钟的新型铝电池可谓是手机党们的福音啦~~

斯坦福大学研究人员已经发明了一种高性能铝电池,这种电池能够实现快速充电,且使用时间长,成本低。研究人员表示,这种新电池能够成为目前所广泛使用的锂电池安全替代品。

“我们已经开发出了一种可充电铝电池,它能够替代目前正在使用的碱性蓄电池和锂离子电池,碱性蓄电池会给环境造成一定破坏,而锂离子电池有时会发生突然起火事故。(所以不少航空公司禁止乘客托运,而新型铝电池正好可以避免这样的尴尬。)斯坦福大学化学教授Hongjie Dai表示,“我们开发出的新电池即便是你凿穿它,也不会着火。”

Researchers at Stanford University, California, say their new aluminium battery could end up with a safe and more convenient energy source than the lithium models used in most mobiles and laptops.

Stanford chemistry professor, Hongjie Dai, said the new device was a breakthrough.

Writing in Nature journal, he said: "We have developed a rechargeable aluminium battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames.

"Our new battery won't catch fire, even if you drill through it.

"Millions of consumers use 1.5-volt AA and AAA batteries. Our rechargeable aluminium battery generates about two volts of electricity.

"That's higher than anyone has achieved with aluminium."

The prototype battery was able to fully charge more than 7,500 times without losing any capacity.

 



Previously, the most an aluminium battery could charge was 100 times, while a lithium battery lasts about 1,000 times before it starts to lose power.

And the device has greater flexibility, meaning it can be used in phones and computers that can be bent and folded.

Current lithium batteries can burst into flames unexpectedly are banned as bulk shipments on some airlines.

However, aluminium batteries will not spontaneously combust, the researchers said.

 

drill through:凿穿

rechargeable:可充电的
