Smashing device for negative electrode material of lithium battery and method thereof

Abstract

The invention discloses a smashing device for a negative electrode material of a lithium battery and a method thereof. The smashing device comprises a base, a smashing box is arranged on the base, andtwo side plates are fixedly installed on the top inner wall of the smashing box; two rotary rollers are rotatably installed on the close sides of the two side plates, a plurality of smashing cuttersare fixedly installed on the outer sides of the two rotary rollers, and two second driving motors are fixedly installed on one side of one of the two side plates; output shafts of the two second driving motors are respectively welded with the ends of the two rotary rollers, a bearing plate is slidably installed on the bottom inner wall of the smashing box, and a sieve plate is rotatably installedon one side of the bearing plate; the sieve plate is located below the rotary rollers, and two baffle plates are fixedly installed on the top of the sieve plate. According to the smashing device, smashed materials can be conveniently sieved and be more uniform for later convenient using, the damping effect is achieved, and the damage of vibration to the device is reduced.

Description

technical field [0001] The invention relates to the technical field of crushing devices, in particular to a crushing device and a method thereof for negative electrode materials of lithium batteries. Background technique [0002] The negative electrode of the lithium-ion battery is made of a negative electrode active material carbon material or non-carbon material, a binder and an additive. The negative electrode materials of lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesocarbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon, etc. The negative electrode materials need to be pulverized and processed when they are used. Yes, but the existing crushing device is inconvenient to sieve large particles and powders when crushing negative electrode materials, resulting in low uniformity of raw materials and affecting subsequent use. Therefore, we propose a lithium battery negative electrode material With p...

AI Technical Summary

Problems solved by technology

[0002] The negative electrode of the lithium-ion battery is made of a negative electrode active material carbon material or non-carbon material, a binder and an additive. The paste adhesive is evenly applied on both sides of the copper foil, dried and rolled. The negative electrode materials of lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesocarbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon, etc. The negative electrode materials need to be crushed and processed when they are used. Yes, but the existing crushing device is inconvenient to sieve large particles and powders when crushing negative electrode materials, resulting in low uniformity of raw materials and affecting subsequent use. Therefore, we propose a lithium battery negative electrode material With pulverizing device and method thereof, be used for solving the above problems
