Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, and more specifically, to a mixing and stirring device for positive and negative electrode materials of batteries. Background Technology

[0002] A lithium-ion battery is a rechargeable battery that primarily functions by the movement of lithium ions between the positive and negative electrodes. During charging and discharging, lithium ions repeatedly insert and extract between the two electrodes.

[0003] A search revealed application CN202121814393.1, entitled "Mixing Device for Lithium-ion Battery Anode Materials." This application addresses the issue that while traditional mixing drums offer high efficiency and good mixing results, traditional mixers are costly and, due to their CNC control, cumbersome and expensive operation. Furthermore, the cost of maintenance and parts replacement for traditional mixers is also high. This application addresses this problem by incorporating a lifting and stirring device. Compared to traditional lithium-ion battery anode material mixers, this device achieves automatic mixing while significantly reducing manufacturing and operating costs. It is also smaller in size than traditional mixers, with the braking mechanism externally located, making maintenance and parts replacement more convenient and cost-effective. However, when using this device, after mixing is complete and materials need to be discharged, operators must first raise and lower the stirring mechanism, then tilt the mixing drum, and manually scoop out the raw materials, which is cumbersome and inconvenient for collection and processing. Further improvements are possible.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
