Abstract

See full text

The present invention provides a Li3V2(PO4)3-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 Li3V2(PO4)3−x(BO3)x (0−2). It is preferable that x be 2−7≦x≦2−3. 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.
