The invention provides a preparation device of a vacuum ball-milling type battery material. The preparation device comprises a box door and a box body, wherein the box door is arranged on the left side of the box body, and a handle and a hinge are arranged on the box door; a thermal insulation layer, a ball milling tank and microwave emitters are arranged in the box body; a coarse powder cavity and a ball milling cavity are formed in the ball milling tank; a coarse powder device, a vacuum pump and an air inlet hole are arranged in the coarse powder cavity; the coarse powder device comprises a rotating shaft and a driving motor; the driving motor is fixed at the upper end of the box body and connected with the rotating shaft; the air inlet hole is formed in the left end of the vacuum pump and communicated with the ball milling tank, and a hole plug is arranged at the air inlet hole; a sieving net and a ball milling device are arranged in the ball milling cavity; the two microwave emitters are arranged on the outer side walls of the left end and the right end of the box body respectively, and waveguide pipes are arranged on the microwave emitters; the two waveguide pipes penetrate through the box body and the thermal insulation layer and arranged oppositely. Oxidation reactions can be reduced, and few materials are consumed; and the efficiency is high through microwave heating preparation.
Description
technical field [0001] The invention relates to a battery material preparation device, in particular to a vacuum ball mill type battery material preparation device. Background technique [0002] Lithium-ion batteries have the characteristics of high specific energy, low self-discharge, high working voltage, environmental friendliness and no memory effect, and have more and more applications. The positive electrode materials for lithium ion batteries are mainly lithium manganese oxide, lithium cobalt oxide, ternary, lithium iron phosphate, and doped or modified products. Lithium battery anode materials are mainly carbon anode materials. At present, the anode materials that have been actually used in lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesocarbon microspheres, petroleum coke, carbon fiber, and pyrolytic resin. carbon etc. [0003] In the preparation process of lithium battery electrodes, carbon and lithium are ...
