摘要： A method for producing a button cell includes providing a cell cup, a cell top and an electrode-separator assembly winding, the electrode-separator assembly winding having a positive electrode and a negative electrode. An electrically insulating seal is applied at least to an outer portion of the cell top casing. The electrode-separator assembly winding is inserted into the cell top. The cell top is inserted into the cell cup to form a housing. A pressure is applied in a radial direction perpendicular to an axis of the electrode-separator assembly winding so as to seal the housing.

摘要： The present disclosure relates to the field of energy storage device, and particularly relates to an electrode member, an electrode assembly and a secondary battery. The electrode member comprises an electrode body and a conductive structure. The conducting layer comprises a first portion having an active material and a second portion extending from the first portion; the second portion comprises a main portion and a transition portion, the transition portion is provided between the main portion and the first portion, and a width of the transition portion is larger than a width of the main portion. The conductive structure is welded with the second portion and extends along a direction away from the first portion, and at least a part of a welding region formed by the second portion and the conductive structure is positioned at the transition portion. The present disclosure can avoid the overcurrent area being significantly reduced caused by the main portion, ensure that every position the electric current passing through has a sufficient overcurrent area, and improve the safety performance of the secondary battery.
