Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. As the demand for higher-energy-density lithium metal batteries increases – for electric vehicles, smartphones, and drones – stability of the SEI has been a critical issue halting their advancement because a salt layer on the surface of the battery’s lithium electrode insulates it and conducts lithium ions.
“This layer is very i...
