Kt KingtronicsSMD  includes an internal element of an anode foil and a cathode foil, and then rolled together with an electrolytic paper.
It attached to external terminals connecting the tabs with the anode or the cathode foils, and sealed in a can case after impregnated with an electrolyte.

the following figure specifically and clearly shows the internal construction of Kingtronics SMD Aluminum Electrolytic Capacitors.
