Strain-graded silicon nanoscoops for high power Li-ion battery anodes

Green Car Congress: Strain-graded silicon nanoscoops for high power Li-ion battery anodes: "A team at Rensselaer Polytechnic Institute (RPI) has developed a functionally strain-graded carbon-aluminum-silicon anode architecture that overcomes the normally poor performance of Li-ion batteries for high power applications involving ultrafast charging/discharging rates.

The new anode materials consist of an array of nanostructures each comprising an amorphous carbon nanorod with an intermediate layer of aluminum that is finally capped by a silicon nanoscoop on the very top. The gradation in strain arises from graded levels of volumetric expansion in these three materials on alloying with lithium."
