覆银硅微通道板用于三维锂离子电池负极研究
Silver-coated silicon microchannel plates for three-dimensional lithium-ion batteries anodes
摘要
Abstract
In this work,a three-dimensional (3-D) anode using a silver-coated Si microchannel plate (Si-MCP) as the active materials was prepared by photo-assisted electrochemical etching followed by electroless deposition.Using lithium foils as the counter electrodes,representative half-cells are fabricated and tested.In galvanostatic charge-discharge (C-D) measurements at 10 mA · g-1 between 0.02 and 1.5 V,our anode exhibits a charge capacity of 3484.7 mAh · g-1 with a coulombic efficiency close to 95.97 ％ in the initial cycle.Based on the cyclicvoltammetry (CV) and the electrochemical impedance spectroscopy (EIS) data,the mechanism about the lithiation of Ag-coated Si-MCP was also studied.关键词
