Liquid microscopy technique reveals new problem with lithium-oxygen batteries


Written by:

Using an advanced, newer microscopy technology that can see the chemical reaction in the liquid environment, researchers have discovered a new reason for lithium oxygen batteries, which promise five more energy energy than lithium ion batteries. Electricity vehicles and cell phones – are slow and dead after some charges / exhaustive tricks. They present their results in journal Nano Energy.

“We were able to see the first time that Lithium Peroxide lithium oxygen batteries are manufactured in liquid electronics, and is a partner for slow and final death of these batteries,” said Associate Professor Raza Shahbaz Yasir. Mechanical and industrial engineering at the University of Illinois at the Chicago College of Engineering and the Leader of the Paper Writer. “This is a new discovery due to the fact that this promise batteries have such a low decrease in performance and production after relatively few charging / exhausted cycles.”

Lithium oxygen batteries have been tantalizing battery researchers for years due to their potential high energy density. But they stop working relatively quickly than slow and other batteries. One of the reasons for this loss is that the battery-lithium-peroxide build on a battery electrode is a chemical reaction. Coated electrodes can no longer enable effective and chemical reactions that eventually stop energy.

But now, Shahbaz Yasser and his colleagues have shown on the nanometer level, using a new transmission electron microscopy technique developed by YC engineering graduate students Kun He and Yifei Yuan, that Lithium Peroxide Battery liquid also shapes in electronics components. Chemical reaction

Shahbaz Yasir said “It is known that Lithium Peroxide is building itself in electronics.” “Now, we can begin to begin with ideas and designs, which either prevent them from doing or preventing anything to maintain the proper work of electronics so that it does not interfere with the operation of the battery. And we can use the new liquid microscope technique to see if we are moving in the right direction. ”

Shahbaz Yasir said, till date, lithium oxygen batteries are just as lab-based prototype, large-scale lithium oxygen batteries for general or commercial use are still a long way. “There are many problems that need to be controlled with Lithium Air Batteries before they can be used for mainstream use, but it is worth knowing that these high-energy density are made of commercially made batteries. Is a big step first. “
