Electrode leading structure and electricity storage electric element adopting thereof

The invention discloses an electrode leading structure of a battery or a super capacitor, which comprises an end cover. The end cover is hermetically fixed at the opening of the electrode end of a battery or capacitor outer casing. A terminal is inserted in the middle of the end cover, and the top end of the terminal extends out of the end cover. The bottom of the terminal is fixedly provided with a stop edge which is used for preventing the terminal from falling, and the top is respectively provided with a terminal leading end and a hollow flanging structure which is arranged around the terminal leading end. An insulation and sealing sleeve is clamped between the terminal and the end cover, and is sleeved on the terminal for sealing the terminal. The invention also discloses an electricity storage electric element which adopts the electrode leading structure. The electrode leading structure adopts a split structure of the terminal and the end cover; one insulation and sealing sleeve is used for sealing and insulating when the terminal is assembled; the flanging structure is sealed and compressed after being flanged; the sealing structure is simple, and is convenient and rapid in installation; and the sealing part is arranged around the terminal, so that the sealing and insulation material is saved.
