| description | Disclosed is a lithium secondary battery including: a cathode formed of a cathode active material including first cathode active material particles and second cathode active material particles; an anode; and a separator interposed between the cathode and the anode. The first cathode active material particle includes a lithium metal oxide including a continuous concentration gradient in at least one region between a central portion and a surface portion. The second cathode active material particles include a constant concentration composition.
本发明公开了一种锂二次电池，其包括：阴极，由包括第一阴极活性材料颗粒和第二阴极活性材料颗粒的阴极活性材料形成；阳极；以及插设在阴极和阳极之间的隔膜。第一阴极活性材料颗粒包括在中心部分和表面部分之间的至少一个区域中包括连续浓度梯度的锂金属氧化物。第二阴极活性材料颗粒包括恒定的浓度组成。 |
