Crystalline-Amorphous Core-Shell Silicon Nanowires as Battery Electrodes


Researchers in Stanford\'s Materials Science department have developed a method that makes use of core-shell nanowires for improved power rate and cycling life for the lithium battery. The technique involves a simple one-step synthesis for growing silicon crystalline-amorphous core-shell nanowires directly onto stainless steel substrates. These core-shell nanowires have high charge storage capacity long cycle life and high power rate. Applications: Lithium ion batteries


(1) High energy density (2) Good cycle performace (3) High power rate
