The invention relates to the technical field of lithium battery materials, in particular to a V2O5-carbon fluoride mixed positive electrode material and a preparation method thereof. According to theinvention, a V2O5 material is doped in a carbon fluoride positive electrode material, so that the advantages that the V2O5 material has higher discharge platform voltage, good high-current discharge capacity, very small heat generation during the discharge process and the like are fully utilized, the problem of voltage lag at the initial discharge stage of the carbon fluoride positive electrode material is solved, the large-current discharge capacity of the carbon fluoride positive electrode material is effectively improved, the rate capability of the lithium carbon fluoride battery is greatlyimproved, the temperature rise during the discharge process of the lithium carbon fluoride battery is reduced, and the application range of the lithium carbon fluoride battery is expanded. Under theaction of a dispersing agent, the two materials are mixed in a high-energy ball milling manner, so that the problem of voltage lag at the initial discharge stage of the carbon fluoride positive electrode material and the problem of high heat productivity under a high-current discharge condition are further solved. According to the present invention, the zirconium oxide balls are added during the high-energy ball milling process, so that the uniformity of the mixed materials is further improved.

The invention provides a reaction still. The reaction still is good in stirring effect, materials in a still body can be evenly mixed, and the quality of products is improved. The reaction still comprises the still body, a stirring shaft is arranged in the still body in the axis direction of the still body, stirring blades are installed on the stirring shaft, one end of the stirring shaft is connected with the output end of a driving device which is fixed above the still body, and a manhole is formed in the upper portion of the still body. The reaction still is characterized in that the stirring blades are spiral belt blades, the number of the spiral belt blades is two, the spiral belt blades are symmetrically arranged on the stirring shaft in a spiral surrounding mode, the blade surfaces of the spiral belt blades are towards the axis direction of the still body, and the spiral directions of the two spiral belt blades are opposite.

The invention discloses a processing technology for preparing high-strength concrete. The processing technology comprises the following steps: (1) raw material preparation: taking cement, sand, water,a water reducing agent, phenolic fiber and montmorillonite, wherein the sand is obtained by crushing construction waste by a crushing apparatus; (2) dry mixing: putting the cement, the sand, the water reducing agent, the phenolic fiber and the montmorillonite into a material mixing machine for dry material pre-mixing to obtain a mixture A after uniform mixing; and (3) wet mixing: putting the mixture A into a stirrer, adding water and a fine aggregate into the stirrer, and then performing uniform stirring to obtain the slurry-like concrete. According to the processing technology, the dry mixing operation is first performed before the wet mixing, so that a mixing uniformity degree of the dry powder materials is relatively high during mixing, and the processing technology ensures that various materials are all mixed together.
