Abstract: The present application provides a positive electrode material, a positive electrode plate, a secondary battery, a battery module, a battery pack, and an electrical apparatus. The positive electrode material comprises a manganese-containing active material and a functionalized carbon nanotube, where a surface of the functionalized carbon nanotube comprises lone pair electrons. The lone pair electrons on the surface of the functionalized carbon nanotube have a strong coordination capability. During charging and discharging of the secondary battery, the lone pair electrons can form a coordination structure with Mn2+ dissolved from the manganese-containing active material, to reduce the dissolution of the Mn2+, thereby improving a manganese dissolution phenomenon of the secondary battery, and then improving cycling performance of the secondary battery.
