Embodiment 1

[0017] A preparation method of basic lead chloride micro-nano structure crystal, the steps are as follows:

[0018] Synthesis of basic lead chloride (Pb(OH)Cl) micro-nano crystals. Take 3 mmol (0.8343 g) of lead chloride (PbCl 2 ), put it into a 100 mL three-necked bottle after grinding, add 80 mL deionized water, stir and heat to 60 o C, forming a clear and transparent solution. 3 mmol (0.42 mL) of triethylamine was added, and white flocs appeared in the solution. After reacting for 10 minutes, the heating was stopped, and the solution was cooled to room temperature. After suction filtration and drying, a solid powder was obtained. (Scanning electron microscope picture, X-ray diffraction picture and absorption spectrum are respectively as figure 1 a, 1b and 1c).

Abstract

The invention discloses a method for preparing an alkali lead chloride micro-nano structure crystal and belongs to the technical field of micro-nano material preparation. The method comprises the following steps: dissolving lead chloride with deionized water, and adding triethylamine to carry out a reaction under a heating condition, thereby obtaining the alkali lead chloride micro-nano structurecrystal. Through suction filtration and drying, powder of the alkali lead chloride micro-nano structure crystal can be made. The prepared alkali lead chloride micro-nano structure crystal takes the shape of a rod, has a length range about 300-1600n m and a thickness range about 30-400 nm, and has the advantages of being simple in synthesis process, good in repeatability, low in cost, safe, and environmentally friendly. On the basis of the characteristics, the crystal has very high values in both laboratory investigation and industrial application.

Description

technical field [0001] The invention relates to the field of preparation of basic lead chloride, in particular to a preparation method of basic lead chloride micro-nano structure crystals. Background technique [0002] In recent years, high-capacity anode materials for lithium-ion batteries have become one of the research hotspots. In the past few years, a variety of transition metal oxides have been reported as high-capacity anode materials for Li-ion batteries, such as CoO, CuO, NiO, and MnO, etc. But these materials are expensive and complicated to make, making them difficult to use as commercial electrode materials. In addition, the catalytic effect of transition metals leads to the decomposition of the electrolyte during the reduction process. Therefore, other inexpensive materials with appropriate metal elements should be developed to meet the requirements of electrode materials for energy storage batteries. [0003] A few years ago, it was reported that basic lead ...
