摘　　要：随着锂电池在电动汽车及可再生能源储存等领域的广泛应用,对其制造工艺的精度与一致性提出了更高的要求。作为锂电池极片制造的核心环节,辊压工艺通过调节辊缝宽度来控制材料厚度的均匀性,从而直接影响电池的性能与安全性。大量研究已表明,辊缝的调节不仅影响材料的压实程度、密实性及导电性,还与电池的充放电效率及循环寿命密切相关。然而,由于材料特性差异及工艺参数的不稳定性,厚度均匀性问题亟待解决。针对辊缝调节对材料厚度均匀性的影响进行的分析,不仅有助于识别并理解现有工艺的不足之处,还为锂电池制造工艺的优化提供了理论依据。对辊压工艺中关键参数与材料特性之间的关系进行深入探讨,将为提升锂电池整体性能及生产效率提供切实可行的解决方案。With the widespread application of lithium batteries in electric vehicles and renewable energy storage,higher requirements have been put forward for the accuracy and consistency of their manufacturing processes.As the core process of lithium battery electrode manufacturing,roll pressing technology controls the uniformity of material thickness by adjusting the width of the roll gap,which directly affects the performance and safety of the battery.Numerous studies have shown that the adjustment of roller gaps not only affects the compaction degree,compactness,and conductivity of materials,but is also closely related to the charging and discharging efficiency and cycle life of batteries.However,due to differences in material properties and instability of process parameters,the issue of thickness uniformity urgently needs to be addressed.The analysis of the impact of roll gap adjustment on material thickness uniformity not only helps identify and understand the shortcomings of existing processes,but also provides a theoretical basis for optimizing lithium battery manufacturing processes.In depth exploration of the relationship between key parameters and material properties in the rolling process will provide practical and feasible solutions for improving the overall performance and production efficiency of lithium batteries.
