Abstract
Certain embodiments of the disclosure relate to a bimodal-type cathode active material for a lithium ion battery. The cathode active material includes a mixture of layered LiCoOlarge particles and manganese-based olivine structural small particles. The manganese-based olivine structural small particles may be represented by chemical formula LiCoMnFePO(0≤x≤1, 0<y≤1, 0≤z≤1, x+y+z=1). An average particle diameter of the large particles may be 16 to 25 μm, and an average particle diameter of the small particles may be 1 to 3 μm. The cathode active material of the disclosure can achieve high energy density and high voltage stability.
