Abstract
The present invention provides a LiV(PO)-based positive active material for a lithium secondary battery, which has high discharge capacity and excellent storage performance, particularly high-temperature storage performance; and a lithium secondary battery made using the positive active material. The positive active material for a lithium secondary battery has general formula LiV(PO)(BO)(0<x≦2). It is preferable that x be 2≦x≦2. Also provided are a positive electrode for a lithium secondary battery containing the positive active material; and a lithium secondary battery including the positive electrode.
