This New Battery Can Keep Your Smartphone Charged For A Week

Constant battery drainage on your smart devices slowing you down? Forget fretting, for a group of researchers from Stanford University has developed rechargeable batteries that offer six times storage over the current lithium-ion batteries that are the industry standard

What does that mean for your devices, you wonder? Quite simply, if the battery received industry acceptance, you need to charge your device only once a week.

It has uses even in the emerging electric automobile industry – current vehicles would be able to travel six times the current distance on a SINGLE recharge!

Meet the powerhouse batteries

The new “alkali-metal-chlorine” batteries work by continuously converting sodium chloride/lithium chloride to chlorine and then back to their original form. Chlorine is a highly reactive gas due to which its exploration as a viable alternative has remained extremely limited until now

The study was published in the journal Nature on August 25 and the impressive range of batteries was actually created by accident.

Hongjie Dai, a Stanford professor along with doctoral candidate Guanzhou Zhu were actually trying to improve current battery capabilities using thionyl chloride, a report by Tech Xplore claims.

For perspective – current commercial lithium-ion batteries have the capacity of 200mAh per gram. 

But these batteries were able to achieve 1,200mAh per gram of charge – a phenomenal feat! 

Uses go beyond conventional technology

While most people immediately think of their smartphones and laptop batteries every time such developments pop up, the scientists behind the achievement have much far-reaching goals for the tech
