Scientists have developed a groundbreaking new lithium battery that could dramatically extend the driving range of electric vehicles (EVs), according to Tech Xplore. Research published in the journal Nature Energy highlights this exciting innovation, which brings us closer to making electric cars more accessible and appealing to drivers everywhere.
The key to these ultra-long-lasting batteries lies in a specially formulated liquid electrolyte that interacts favorably with the highly reactive lithium metal in the battery. By improving the stability of the interface between the electrolyte and lithium, the battery can withstand many more charge cycles, resulting in more miles on the road for EV drivers.
Researchers from Penn State, the University of Illinois Chicago, and Argonne National Lab collaborated to address the challenge of battery longevity. They synthesized a fluorinated cyclic ether with minimized lithium-ion coordination capability and enhanced electrochemical stability, playing a crucial role in manipulating the solid electrolyte interphase (SEI) formation process by differentiating the contribution of dual anions to the SEI layer.
In simpler terms, their secret ingredient is a compound called HFTHP, which helps create a sturdy protective layer on the lithium metal surface. This protective layer prevents the battery degradation that typically limits EV range, thereby significantly improving battery life and performance.
