A special equipment for producing silicon-carbon composite materials and its application method

Abstract

The invention discloses a special equipment for producing silicon-carbon composite materials and a method for using the same. The special equipment for producing silicon-carbon composite materials includes a mixing tank, and positioning rods are fixedly installed on both sides of the top of the mixing tank. The same cover plate is movable on the positioning rod. Both sides of the bottom of the cover plate are provided with mounting holes matching the positioning rod. The positioning rod is movably installed in the corresponding mounting hole. The bottom of the cover plate is provided with two Two air outlets are arranged symmetrically, and the two air outlets are located between the two installation holes. A snap ring is fixedly installed on the side wall of the air outlet, and a sealing gasket is placed on the top of the snap ring. The top of the sealing gasket is fixedly installed with a sliding pole. The invention is simple in structure, easy to operate, easy to increase the sealing between the cover plate and the mixing tank, and easy to increase the sealing between the sealing gasket and the snap ring, realizes the one-way conduction function of the air outlet, and is convenient to discharge into the mixing tank air.

Description

technical field [0001] The invention relates to the technical field of production and preparation of silicon-carbon composite materials, in particular to a special equipment for producing silicon-carbon composite materials and a method for using the same. Background technique [0002] When silicon material is used as the negative electrode material of lithium-ion batteries, it has a specific capacity as high as 3580mAh / g at room temperature, but the huge volume expansion that occurs when silicon is alloyed with lithium leads to self-pulverization. Poor, which seriously affects the performance of silicon materials in batteries; after retrieval, the patent document with application number 201610557191.0 discloses a special equipment for producing silicon-carbon composite materials. The main structure is composed of a bracket, a mixing chamber and a sealing cover. The upper end of the cover is provided with an explosion-proof rotating motor, and the explosion-proof rotating mot...

Problems solved by technology

[0003] However, the above-mentioned design is inconvenient to increase the sealing between the mixing chamber and the sealing cover, and when argon gas is introduced into the mixing chamber, neither the vent port nor the exhaust port has unidirectional conductivity, and it is inconvenient to quickly discharge the argon in the mixing chamber. Air affects the production efficiency of silicon-carbon composite materials, so we propose a special equipment for producing silicon-carbon composite materials and its use method to solve the above problems
