Description

[0001] The utility model relates to the technical field of processing positive and negative electrode materials of batteries, in particular to a device for crushing positive and negative electrode materials of batteries. Background Art

[0002] The main benefit of crushing the positive and negative electrode materials of batteries is that it can increase their specific surface area, thereby increasing the effective contact area for reaction, improving reaction efficiency and diffusion rate. Specifically, crushing the positive and negative electrode materials of batteries can bring the following benefits:

[0003] (1) Improve energy density: After the positive and negative electrode materials of the battery are crushed, their specific surface area will be greatly increased, thus providing more reactive sites and improving the energy density of the battery;

[0004] (2) Improve cycle performance: The positive and negative electrode materials can be crushed into smaller and more uniform particles, which increases the transmission channels of ions and electrons, slows down the loss and corrosion of electrode materials, and thus improves the cycle life of the battery;

[0005] (3) Improve power density: The positive and negative electrode materials can obtain a larger specific surface area after being crushed, providing more reaction sites during the battery charging and discharging process, thereby improving the power density of the battery;

[0006] (4) Improve charging speed: After the positive and negative electrode materials are crushed, their particles are smaller and the powder is more uniform, the internal impedance of the battery is reduced, and the charging speed is improved.

[0007] During the production of positive and negative electrode materials for batteries, the raw materials (powders) must be sintered before pouring. However, after sintering, the positive and negative electrode materials clump together, making them difficult to pour and unable to meet usage requirements. Therefore, the agglomerated positive electrode materials must be broken down before pouring. Existing methods of pulverizing positive and negative electrode materials in one go are ineffective, with some materials failing to reach the required particle size, thus affecting the final battery performance.

[0040] Specific working process:

[0041] The sagger 6 containing the positive and negative electrode materials of the compacted battery is transferred from the conveying assembly 3 to the crushing mechanism 1. After being transferred to the working position, the blocking cylinder 42 of the blocking member 4 drives the blocking bracket 41 to rise, so that the blocking roller 44 extends from the roller gap of the conveying assembly 3, restricting the sagger 6 from moving forward, and the symmetrically arranged horizontal push cylinders on the transmission assembly 3 center the sagger 2. The lifting cylinder of the lifting member 5 drives the lifting guide frame 53 to rise, so that the lifting support plate 54 extends from the roller gap of the conveying assembly 3 to lift the sagger 6. The lifting frame 13 of the crushing mechanism 1 is extended and driven by the servo electric cylinder 12 to move downward, and the cutter 14 is inserted downward into the compacted positive and negative electrode materials of the battery in the sagger 1. At the same time, the reduction motor 16 drives the main gear 17 to rotate, and the main gear 17 drives each transmission gear 19 to rotate, so that the cutter 14 crushes the material in the sagger 6.

[0042] The sagger 6 containing the crushed positive and negative electrode materials of the battery is transferred to the peeling mechanism 2. After being transferred to the working position, the blocking cylinder 42 of the blocking member 4 drives the blocking bracket 41 to rise, so that the blocking roller 44 extends from the roller gap of the conveying assembly 3, restricting the sagger 6 from moving forward, and the symmetrically arranged horizontal push cylinders on the conveying assembly 3 center the sagger 2. The lifting cylinder of the lifting member 5 drives the lifting guide frame 53 to rise, so that the lifting support plate 54 extends from the roller gap of the conveying assembly 3 to lift the sagger 6. The lifting frame 23 of the peeling mechanism 2 is extended and driven by the cylinder 22 to move downward, and the pins 24 on the four edges of the lower connecting plate 231 move toward the sagger 2 containing the crushed positive and negative electrode materials of the battery, and planing off the residual material on the edge wall of the sagger 2, so that the inner wall of the sagger is neat and clean without any material residue.

[0043] This embodiment integrates cracking, fragmentation and crushing into one, which saves design costs and improves work efficiency. It solves the problem of materials remaining on the inner wall of the sagger 6 after sintering and cannot be removed, and can ensure the crushing effect, so that all positive and negative electrode materials reach the required particle size of the materials, which will not affect the final performance of the battery.
