Example Embodiment
[0067] Example 1
[0068] A copper copper composite tuner, a copper foil of a lithium copper composite belt is a double-sided photopolymer copper foil, a thickness of 8 μm, a width of 200 mm, and a lithium layer thickness 25 μm, a width of 150 mm. The above lithium copper composite belt is placed in a sealed space, wherein the environmental humidity of the closed space is controlled at 50 to 55%, the closed space of N. 2 O 2 The mass ratio is 7: 1, CO 2 The concentration range is 0.5%; the reaction of the lithium copper composite belt and the mixed gas can be changed in minutes. Lithium copper composite belt and mixed gas first happen figure 1 The reaction shown in S1-2 produces lithium hydroxide, lithium nitride, lithium oxide, and lithium layer forming loose porous structure, accelerates lithium metal nitriding, oxidation, then lithium nitride, lithium oxide continuous and water The hydrolysis reaction shown in S1-3 produces lithium hydroxide. The above lithium hydroxide adsorpt...

[0084] Example 2
[0085] A copper copper composite tuner, a copper foil of a lithium copper composite belt is a double-sided photopolymer copper foil, a thickness of 8 μm, a width of 200 mm, and a lithium layer thickness 25 μm, a width of 150 mm. The above lithium copper composite belt is placed in a closed space, wherein the environmental humidity of the closed space is controlled at 65 to 70%, the closed space. 2 O 2 The mass ratio is 7: 1, CO 2 The concentration range is 0.5%; the reaction of the lithium copper composite belt and the mixed gas can be changed in minutes. Lithium copper composite belt and mixed gas first happen figure 1 The reaction shown in S1-2 produces lithium hydroxide, lithium nitride, lithium oxide, and lithium layer forming loose porous structure, accelerates lithium metal nitriding, oxidation, then lithium nitride, lithium oxide continuous and water The hydrolysis reaction shown in S1-3 produces lithium hydroxide.
