Na-ion battery investigation of Si,SixGe1-x and Ge NWs. In this study we examine the roles of amorphization and elemental compositions in determining the reversibility of Na alloying. The study shows that amorphization unlocks the cycling ability, with Si0.5Ge0.5 NWs showing the best capacity retention
Li-ion battery anodes formed using copper silicide nanowires as high surface area hosts for Si NW growth. The complex branched nanowires and high density growth allowed for increased areal capacities, towards practical devices.
Review on low temperature operation of Li-ion batteries, with particular focus on anode related mechanistic issues. Includes recent material advances and an examination of future opportunities to develop better performing, low temperature batteries.
