Lithium-related discovery could extend battery life and improve safety

07.03.2018 | Tech Xplore | techxplore.com

Lithium-metal batteries are among the most promising candidates for high-density energy storage technology in an expanding range of digital “smart” devices and electrical vehicles, but uncontrolled lithium dendrite growth, which results in poor recharging capability and safety hazards, currently tempers their potential.

Dendrites are needle-like growths that appear on the surface of lithium metal, which is used as the anode, or negative electrode, of a battery. They induce unwanted side reactions that reduce energy density, and at worst, cause shorting of the electrodes that can lead to fires or explosions.

Better lithium-metal batteries

New research from Arizona State University that involves using a 3-dimensional layer of Polydimethylsiloxane (PDMS), or silicone, as the substrate of lithium metal anode has been found to mitigate dendrite formation and stands to both dramatically extend battery life and diminish safety risks.
