Redesigning structural batteries with cartilage electrolytes

A safe, rechargable, zinc “structural battery” was created by University of Michigan researchers. The battery uses a cartilage-like material to stop the formation of dendrites while allowing zinc ions to travel between electrodes: https://news.engin.umich.edu/2019/01/... ----- Watch more videos from Michigan Engineering:    / michiganengineering   The University of Michigan College of Engineering is one of the world’s top engineering schools. Michigan Engineering is home to 12 highly-ranked departments, and its research budget is among the largest of any public university. http://engin.umich.edu/ ----- More on the video: Structural batteries could reduce weight and improve efficiency for electric vehicles and devices by storing energy in structural components—the wing of a drone, the bumper of an electric vehicle, or the enclosure of a tablet, for example. But structural batteries have so far been heavy, short-lived or unsafe. Nicholas Kotov, the Joseph B and Florence V Cejka Professor of Engineering at U-M, has been working to find new designs for structural batteries to make them safe, small, and rechargeable. “Cartilage turned out to be a perfect prototype for an ion-transporting material in batteries," says Kotov. "It has amazing mechanics, and it serves us for a very long time compared to how thin it is. The same qualities are needed from solid electrolytes separating cathodes and anodes in batteries." For now, the zinc batteries are best as secondary power sources because they can’t charge and discharge as quickly as their lithium ion brethren. But Kotov’s team intends to explore whether there is a better partner electrode that could improve the speed and longevity of zinc rechargeable batteries. Kotov is a professor of chemical engineering, biomedical engineering, materials science and engineering, and macromolecular science and engineering. http://www.umkotov.com/ Read the paper: “Biomimetic solid-state Zn2+ electrolyte for corrugated structural batteries,” ACS Nano (2019). https://pubs.acs.org/doi/10.1021/acsn...
