    • A lithium secondary battery is provided with a positive electrode, a negative electrode (1), a separator interposed between the positive and negative electrodes, and an electrode assembly having the negative electrode (1), the positive electrode, and the separator. The negative electrode (1) has a negative electrode current collector (11) and negative electrode active material layers (12), (13) formed on respective surfaces of the negative electrode current collector (11). The negative electrode active material layers are composed of an alloy containing silicon, which intercalates and deintercalates lithium, and iron, which does not intercalate or deintercalate lithium. At least a portion of the electrode assembly has a curved portion in which the negative electrode active material layer (13) disposed inward relative to the negative electrode current collector contains a higher concentration of the iron than the negative electrode active material layer (12) disposed outward relative to the negative electrode current collector.
    • 锂二次电池设置有正极,负极(1),介于正极和负极之间的隔板以及具有负极(1),正极和隔板的电极组件。 负极(1)具有形成在负极集电体(11)的各表面上的负极集电体(11)和负极活性物质层(12),(13)。 负极活性物质层由含有硅的合金,其插入和脱嵌锂,以及不插入或脱嵌锂的铁。 电极组件的至少一部分具有弯曲部分,其中相对于负极集电体向内设置的负极活性材料层(13)含有比设置的负极活性材料层(12)更高的铁浓度 向外相对于负极集电体。
