Positive electrode active material for lithium secondary battery |
| abstract |
It relates to a lithium secondary battery using a positive electrode active material that operates with a charging voltage in a region exceeding 4.3V, and proposes a new positive electrode active material for lithium secondary batteries that can further increase output characteristics. In the metal Li reference potential, at least on the entire surface or a part of the surface of the lithium manganese-containing composite oxide particles (also referred to as ``core particles'') operating at a charging voltage in a region exceeding 4.3 V, at least Ti or Al or Zr A positive electrode active material for a lithium secondary battery containing two or more types of positive electrode active material particles having a layer A containing C is proposed. |
