Beschreibung
Zusammenfassung:A positive electrode material for a lithium battery, a positive electrode prepared from the positive electrode material, and a lithium battery including the positive electrode are disclosed. The positive electrode material includes a positive active material, an aqueous binder, and tungsten trioxide. Due to the inclusion of the positive active material, the aqueous binder, and the tungsten trioxide (WO 3 ), the positive electrode material may substantially prevent corrosion of an aluminum substrate. The positive electrode material has high electric conductivity. Lithium batteries including positive electrodes prepared from the positive electrode material have decreased resistance of the electrode plate, high rate characteristics, and good lifespan characteristics.
