How microscopes are improving EV batteries at PNNA
Filed under: Emerging Technologies, EV/Plug-in, USA
The construction of one small battery is helping scientists make a big breakthrough when it comes to studying the effects of repeated recharging of a rechargeable battery.
The Pacific Northwest National Laboratory (PNNA), working with US Department of Energy's Environmental Molecular Sciences Laboratory, built a dime-sized battery and used a microscope to study what was going on inside. The microscopic view allowed scientists to check out the ebb and flow of positively charged ions in "wet" form, when they're bathed in electrolytes.
When ions are going back and forth, they "deform" and wear down the electrodes, eventually affecting the performance of the rechargeable batteries, and this happens in the batteries used in plug-in vehicles as well. Viewing this process through microscopes when those ions are in "wet" form will likely allow scientists to better study how and why rechargeable batteries eventually wear down after a certain amount of time and use.
The PNNL continues to turn to the microscope to study battery wear. In late 2010, researchers used high-resolution imagery to get a better picture of how electrode wires within rechargeable lithium-ion batteries contort as the cells are charged. One finding was that nano-sized wires may be more suitable for lithium-ion batteries, the PNNL said at the time. Check out the PNNL's press release below.Continue reading How microscopes are improving EV batteries at PNNA
