摘要：
A negative electrode (1) for nonaqueous electrolyte secondary batteries is characterized by comprising an active material layer (5) and a metal lithium layer (3) between a pair of surface layers (4) for current collection. The negative electrode (1) has two negative electrode precursors (2) respectively comprising a surface layer (4) for current collection and an active material layer (5) arranged on one surface of the surface layer (4) for current collection, and a metal lithium layer (3) is interposed between the negative electrode precursors (2) in such a manner that the active material layers (5) of the negative electrode precursors (2) are opposite to each other and respective surface layers (4) for current collection of the negative electrode precursors (2) face the outside. In each active material layer (5), a metal material having a low lithium compound-forming power is permeated throughout the entire active material layer (5) in the thickness direction.
摘要（中）：
非水电解质二次电池用负极（1）的特征在于，在一对表层（4）之间具有用于集电的活性物质层（5）和金属锂层（3）。 负极（1）具有分别包括用于集电的表面层（4）和布置在表面层（4）的一个表面上用于集电的活性物质层（5）的两个负极前体（2） 金属锂层（3）以负极前体（2）的活性物质层（5）彼此相对的方式插入在负极前体（2）之间，并且各自的表面层（4）用于电流 负极前体（2）的收集面向外部。 在每个活性物质层（5）中，具有低锂化合物形成能力的金属材料在整个活性物质层（5）的厚度方向上渗透。
