模头狭缝涂布是锂离子电池(LIB)电极制造的核心工艺。然而高固含量、高粘度的浆料在传统狭缝内易形成泊肃叶流动,导致出口速度分布不均、产生涂布缺陷并降低电池性能。受白斑河豚 %% Takifugu alboplumbeus本研究提出了一种仿生锥形均流结构。该结构通过调控浆料在狭缝内的剪切稀化效应,打破泊肃叶分布,从而实现出口速度的均匀化。具体而言,通过数值模拟优化了狭缝几何参数(间隙:0.2 mm,长度:25 mm)与仿生锥形结构的特征参数(= 0.79 mm,优化后的结构实现了0.999的出口速度均匀性,显著优于现有流动均化方法。随后,我们制备了仿生锥形垫片并将其应用于狭缝模头电极涂布工艺。结果表明,与传统平壁垫片相比,该设计使涂层厚度偏差降低了285倍,达到2.78×10<sup>-3</sup>(基板速度=2.86米/分钟)。微米。此外,经优化设计的电极组装成软包电池后,在2C倍率下循环200次仍保持70.3%的容量,显著高于传统电极36.0%的容量保持率。该仿生均流策略无需复杂模具改造,在成本效益与均流性能之间实现了平衡,为高性能锂离子电池电极的工业化制备提供了新路径。b = 2.86 mm). The optimized structure achieved an outlet-velocity uniformity of 0.999, significantly superior to existing flow-homogenizing methods. Subsequently, a bionic conical shim was fabricated and applied in a slot die for electrode coating. The results showed that the coating thickness deviation was reduced by a factor of 285× compared with that of the traditional flat-walled shim, reaching 2.78 × 10−5 μm. Additionally, the optimized electrode assembled into a soft-pack battery retained 70.3% of its capacity after 200 cycles at 2C, much higher than the 36.0% capacity retention of the traditional electrode. This bionic flow-homogenizing strategy requires no complex mold modification and balances cost-effectiveness with flow-homogenizing performance. It provides a new pathway for the industrial fabrication of high-performance LIB electrodes.
