摘　　要：高耐穿刺性、高机械强度、轻薄等一直是软包锂离子电池包装膜的发展趋势。相对于传统铝塑膜中的铝箔,不锈钢箔拥有很高的机械强度以及硬度,所以利用超薄不锈钢箔(厚度≤20μm)制备钢塑膜会是今后锂离子电池包装材料的研究热点。从超薄钢塑膜的生产工艺、存在问题以及后续改进措施三个方面介绍超薄钢塑膜。High puncture resistance,high mechanical strength,lightness and thinness have always been the development trend of soft packaged lithium-ion battery packaging films.Compared with aluminum foil in traditional aluminum plastic film,stainless steel foil has high mechanical strength and hardness.Therefore,the use of ultra-thin stainless steel foil(thickness≤20μm)to prepare steel plastic film will be a research hotspot for lithium-ion battery packaging materials in the future.This paper introduced the ultra-thin steel plastic film from three aspects:its production process,existing problems and follow-up improvement measures.
