Abstract: A manufacturing method of a lithium battery negative electrode at least includes the following steps. An electroplating equipment is provided, wherein the electroplating equipment has a drying chamber, and the drying chamber includes an electroplating tank, an electroplating wheel set, and a film sticking wheel set. A copper foil is disposed in the drying chamber. The electroplating wheel set transports the copper foil to form a lithium metal layer on the copper foil, and the copper foil and the lithium metal layer form a copper-lithium composite metal layer. The film sticking wheel set transports the copper-lithium composite metal layer and attaches a protective film to the copper-lithium composite metal layer.

Abstract: An infrared reflective material, a method for producing the same, and an infrared reflective structure are provided. The method includes a preparation step implemented by mixing antimony and zirconium tungstate through a sol-gel manner to form zirconium tungstate composite powders doped with the antimony; a sintering step implemented by sintering the antimony and the zirconium tungstate in the zirconium tungstate composite powders doped with the antimony in a temperature gradient within a range from 500° C. to 1,100° C. for a predetermined time period, so that the antimony and the zirconium tungstate in the zirconium tungstate composite powders doped with the antimony bond together to form into composite tungsten oxide powders; a grinding step implemented by grinding the composite tungsten oxide powders; and a mixing step implemented by mixing the composite tungsten oxide powders that are grinded into an acrylic resin to form the infrared reflective material.
