锂离子二次电池及锂离子二次电池之制造方法;LITHIUM ION SECONDARY BATTERY AND METHOD FOR PRODUCING LITHIUM ION SECONDARY BATTERY

摘要

本发明系一种锂离子二次电池，其特征在于具备：积层体，其系将具有端子引板(terminal tab)之电极板与半固体或固体状之电解质层交替地积层而成；及片状之包装材料，其将该积层体收纳于内部，且使端子引板之一部分突出而密封；且于上述包装材料，设置有邻接于上述积层体之端缘之至少一部分并密封上述积层体的积层体邻接密封部。; and a casing material which accommodates therein the laminate and is sealed with the terminal tabs protruding therefrom, wherein the casing material has a laminate-adjacent sealed portion which is positioned adjacent to at least a portion of the laminate and seals the laminate.
