Abstract
A positive active material, comprising a lithium transition metal composite oxide containing Co and R elements and an M element. The lithium transition metal composite oxide has a P6mc crystal structure. The M element includes at least one of Al, Mg, Ti, Mn, Fe, Ni, Zn, Cu, Nb, Cr, Y, or Zr. The R element includes at least one of F or Cl. A molar content of the R element is n, a sum of a molar content of the Co element and a molar content of the M element is n, and a ratio δ of nto nis 0<δ≤0.01. The crystal structure of the positive active material according to this application is highly stable, thereby improving cycle performance and thermal stability of the electrochemical device.
