Researchers used the omics of cellular science approach to understand the reactions between the multiple components of the electric battery.
Biologists use omics to better understand cellular systems and this approach has helped improve lithium batteries for electric aircraft too.Researchers at the Lawrence Berkeley National Laboratory and the University of Michigan turned to modern biology laboratories to seek methods to improve battery performance in electric aircraft. Technology helping us better understand our cells could also unlock a future of emission-free air travel.
According to Youngmin Ko, a postdoctoral researcher at Berkeley Lab, conventional batteries are not designed to fulfill this dual role. This is partly due to our lack of understanding of how complex reactions work at the anode, cathode, and between the electrolyte. Biologists have been trying to understand the role of cell components and their complex interactions for centuries.
They focused their attention on lithium-ion batteries, which are extensively used in the market today but have yet to be able to address long-haul transportation demands. Using the omics approach, the researchers determined that the inability of lithium batteries to provide high power for sustained periods was not a problem of the anode, as believed. Instead, it was the cathode that was the root cause.
“We found that mixing salts in the electrolyte could suppress the reactivity of typically reactive species, which formed a stabilizing, corrosion-resistant coating,” added Ko in a press release.
