摘要：

In this work, mesoporous silicon (PSi) Membrane was investigated for potential application as anode in lithium-ion batteries (LIBs). Free-standing mesoporous silicon Membranes with a thickness of about 28 mu m and porosity around 80% were prepared by electrochemical etching of a p(+) type silicon wafer. Galvanostatic charge/discharge measurements were conducted on freestanding porous Si Membrane. A specific capacity of about 1870 mA h g(-1) with a Coulombic efficiency of 93.8% in the first charge/discharge cycle was measured. After 80 cycles the capacity retention has been slightly increased to 94.5%, attributed to the high porosity and the high surface area of the PSi Membrane and the stabilization of the solid-electrolyte interphase (SEI). The investigation of the PSi surface after 80 cycles by SEM indicates that the morphology of PSi electrode is still maintained and the pore diameters have been increased by about 30% during lithiation.
