摘要
Silicon is a promising alternative anode material due to its high theoretical specific capacity. However, the application of silicon is limited by the poor cycling stability associated with its large volume changes during the charging/discharging processes and its low conductivity. Herein, we design and fabricate an Ag-deposited 3D porous Si composite. The 3D channel can effectively buffer the volume change of Si and the deposited Ag can enhance the conductivity of 3D porous Si. So the Ag-deposited 3D porous Si anode exhibits significantly improved lithium-storage performance.
