New research led by an electrical engineer is aimed at improving lithium-ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers created nanowires that block diffusion of lithium across their silicon surface and promote layer-by-layer axial lithiation of the nanowire's germanium core.<img src="http://feeds.feedburner.com/~r/sciencedaily/~4/5uOWv0XtEK8" height="1" width="1"/>
