RESEARCHING A SAFER LITHIUM BATTERY

- May 25, 2018 -

Our gadgets nowadays are all powered by Lithium-ion batteries have become an indispensable power source. And with the instability of the lithium battery and safety hazard, scientists are trying to find a way to track lithium ions and make them safer.


Rechargeable batteries work by shuttling ions back and forth between electrodes through an electrolyte and sometimes failure occurs when lithium ions stray from their intended path.


Different methods have been proposed by scientists to track the ions but so far, they have been limited for various reasons.


A new method called Fluorescence microscopy to probe materials and biological systems, could help understand better. Scientists will first need to find a fluorescent label that is sensitive to lithium ions.


Using 2- naphthoxazole or HPNO, the researchers worked with a molecule that fluoresces when it attaches to lithium ions and by adding a visible pump that will help prevent photo bleaching and other damages.


Under those circumstances, the system could image and track lithium ions. To obtain better results, the next test will be to put the molecule in a lithium battery cells environment.
