Description

Technical Field

[0001] This invention relates to the field of electrolyte production, and more particularly to a continuous extrusion molding equipment for composite solid electrolytes. Background Technology

[0002] Composite solid-state electrolytes have become a research hotspot in the lithium-ion battery field due to their high safety, wide electrochemical window, and excellent ion conductivity. Their molding quality directly affects the battery's energy density and cycle life. However, current production equipment for composite solid-state electrolytes suffers from several drawbacks: Firstly, traditional batch mixing and molding equipment has low production efficiency, and materials are prone to uneven dispersion and localized overheating during mixing, leading to internal structural defects in the electrolyte and reduced ion conductivity. Secondly, existing continuous equipment lacks sufficient metering accuracy, making it difficult to precisely control the proportions of various raw materials. Furthermore, extrusion devices often employ a single-spiral structure, limiting the mixing and shearing effect and hindering thorough material blending. In addition, the post-molding segmentation process relies heavily on manual or semi-automated equipment, resulting in low segmentation accuracy, burrs on the edges, low integration of functional modules, cumbersome operation, and high maintenance costs, making it difficult to meet the demands of large-scale, high-quality production. Therefore, this paper proposes a continuous extrusion molding equipment for composite solid-state electrolytes. Summary of the Invention
