摘要:
Disclosed are an electrode having a porous active coating layer, a manufacturing method thereof and an electrochemical device containing the same. The electrode having a porous active coating layer according to the present invention may be useful to enhance peeling and scratch resistances of the porous active layer and improve a lamination characteristic toward the porous active layer by introducing a porous active layer onto a porous substrate having pores, the porous active layer having heterogeneity of morphology toward a thickness direction in which a content ratio of the binder polymer/inorganic particles present in a surface layer is higher than that of the binder polymer/inorganic particles present inside the surface layer. Accordingly, the stability and performances of the battery can be improved at the same time since the detachment of the inorganic particles from the porous active layer may be reduced during the assembly process of the electrochemical device.
摘要(中):
公开了具有多孔活性涂层的电极,其制造方法和包含该多孔活性涂层的电化学装置。 具有根据本发明的多孔活性涂层的电极可用于增强多孔活性层的剥离和耐划伤性,并且通过将多孔活性层引入到具有孔的多孔基材上来改善对多孔活性层的层压特性, 存在于表面层中的粘合剂聚合物/无机粒子的含量比高于存在于表面层内的粘合剂聚合物/无机粒子的厚度方向的厚度方向的异质性的多孔质活性层。 因此,可以同时提高电池的稳定性和性能,因为在电化学装置的组装过程中可以减少无机颗粒从多孔活性层的分离。
