Description
Summary:This paper reports on the electrochemical and photo-(electro)chemical fabrication of a single-crystalline porous InP anode, and its performance in Li-ion batteries. This anode exhibits high capacity per area (∼63 mAh/cm2). It consists only of the active material (InP) and a thin Au layer as a current collector. The maximum possible capacity of InP (∼800 mAh/g) is achieved, which is much higher than the capacity of commercial graphite anodes (∼350 mAh/g). The total anode capacity is freely scalable by adjusting the InP membrane thickness. The paper also shows the fabrication processes and a thorough battery characterization by cyclovoltammetry and battery cycling tests in half-cells.
