Description

Technical Field

[0001] This utility model relates to the field of battery electrolyte technology, specifically a stirring device for the production of solid-state battery electrolytes. Background Technology

[0002] Solid-state battery electrolytes are materials with ion-conducting capabilities in a solid state, distinct from liquid electrolytes. They are typically composed of solid materials such as oxides, sulfides, or mixed conductive oxides, which possess high ion conductivity and good chemical stability. In solid-state batteries, the electrolyte plays a crucial role in ion transport, ensuring both battery safety and stability. Compared to liquid electrolytes, solid-state electrolytes more effectively prevent safety issues such as electrolyte leakage and thermal runaway, and hold promise for using positive and negative electrode materials with higher specific capacities, thereby significantly improving battery energy density. With continuous technological advancements, the application prospects of solid-state battery electrolytes are increasingly broad.

[0003] Solid-state batteries represent a crucial future direction for battery technology, and the uniformity of their electrolyte is paramount to battery performance and safety. To ensure optimal performance of solid-state electrolytes, stirring devices play a vital role in the preparation process. Stirring effectively disperses the components of the solid-state electrolyte uniformly, thereby improving the battery's ionic conductivity and overall performance. However, existing stirring devices have several significant shortcomings in practical applications. First, the stirring force of existing devices is often insufficient, failing to effectively break up particle aggregation in the solid-state electrolyte, resulting in uneven material dispersion. Solid-state electrolytes are typically composed of components with different particle sizes and shapes; insufficient stirring force can easily cause particle agglomeration, affecting the electrolyte's ion mobility and thus reducing the battery's charge-discharge efficiency. Second, existing stirring devices lack ease of design, making disassembly and cleaning inconvenient. This not only increases production time costs but also makes changing between different batches of materials difficult. To maintain the cleanliness of the stirring device and avoid cross-contamination, designing a stirring device that is easy to disassemble and clean is particularly important. Utility Model Content

[0027] Working Principle: In this efficient electrolyte particle processing flow, solid electrolyte particles are first smoothly and accurately introduced into the interior of the tank 1 via a precisely designed feed pump 10. This step ensures that the electrolyte particles are evenly distributed in the initial area of ​​the tank 1, laying a good foundation for subsequent processing. Next, the drive unit 3 is activated. This component consists of a high-performance motor 31 and a precision planetary gear set 32, ensuring efficient and stable power transmission. Driven by the drive unit 3, the rotating rod 4 and the connected fixed frame 6 begin to rotate in tandem. This movement drives the rotation of the stirring blades 5. The stirring blades 5 are carefully designed, with their shape and arrangement maximizing stirring efficiency, ensuring that the electrolyte particles are evenly and thoroughly stirred within the tank 1. After the stirring process is complete, the discharge pump 11 is activated. The thoroughly stirred electrolyte particles are smoothly discharged from the tank 1, facilitating subsequent processing or storage steps. When maintenance or replacement of the stirring device is required, the entire disassembly process is equally simple and quick. First, the operator only needs to remove the bolts used for fixing on the mounting bracket 8 from the tank cover 2 one by one. Subsequently, by adjusting the position of the mounting bracket 8, the lid 2 can be easily separated from the barrel 1, thereby exposing the internal stirring device. This design not only simplifies the disassembly process but also greatly improves the maintainability and flexibility of the equipment, allowing operators to quickly install, remove, or replace the stirring device as needed.
