1. A capacitor structure, comprising:
a parallel cell combination, the parallel cell combination comprising a plurality of cells and a plurality of current collectors;
wherein in the parallel cell combination:
the plurality of cells comprising respective first poles and respective second poles are connected in parallel, the first poles and the second poles of the plurality of cells are respectively connected in parallel, and the first poles and the second poles are respectively connected with other devices other than the parallel cell combination through confluence points; and
the first poles and the second poles of each two adjacent cells of the plurality of cells are respectively connected through the plurality of current collectors, and current-carrying specifications of each of the plurality of current collectors is lower than current-carrying requirements of a respective confluence point of the confluence points of a corresponding pole of the first poles and the second poles.
