主权项 1. An anode, comprising: a first layer including a plurality of metal fibers with a three-dimensional (3D) network structure, the 3D network structure including pores between the metal fibers filled with a metallic material, a porosity of the 3D network structure in a range of 50% to 98% and the pores having a size in a range of 50 μm to 600 μm; and a second silicon-containing layer having a predetermined thickness without metal fibers, the second silicon-containing layer on a surface of the first layer including the 3D network structure of the plurality of metal fibers, in the 3D network structure of the metal fibers, or on the surface of the first layer including and in the 3D network structure of the metal fibers, wherein the second silicon-containing layer is separate from the first layer and has a predetermined thickness without metal fibers, wherein the thickness of the second silicon-containing layer is from about 10 nm to about 0.3 μm, and wherein the anode further includes a glue layer between the metal fibers and the silicon-containing layer, the glue layer including a metallic material which is at least one selected from the group of titanium, copper, nickel, aluminum, silver, tin, magnesium, cobalt, manganese, molybdenum, vanadium, tungsten, and bismuth.
