Beschreibung
Zusammenfassung:	The invention discloses a preparation method of an element doping manganese dioxide electrode material for a super capacitor, which is characterized by comprising the following steps: (1) synthesizing a LiAxMn2-xO4 powder material with a spinel structure by utilizing a suitable method, wherein A is selected from metallic addictive elements Ti, Ni, Sn, Co, Zn and Al, and x is within the range of 0.01-0.25%; and (2) utilizing lithium ion removal agent to remove lithium ions from the LiAxMn2-xO4 powder material obtained from step (1) under the condition of not destructing the spinel structure of a precursor, thereby obtaining the element-replacement MnO2-doping electrode material for the super capacitor. For the element doping manganese dioxide electrode material prepared by the invention, the Mn part in a lattice can be evenly replaced by doped elements, and the method has high industrial maturity and is a way with great potential for preparing the manganese dioxide electrode material for the super capacitor.
