NOVELTY - A cell comprises a layer of cell unit comprising a positive pole sheet, a negative pole sheet, and a membrane (7) between the positive pole sheet and the negative pole sheet. The positive pole sheet comprises a positive pole battery active substance (1), a positive pole capacitor active substance (3), and a positive pole current collecting body (5). The negative pole sheet comprises a negative pole battery active substance (2), a negative pole capacitor active substance (4), and a negative pole current collecting body (6).    USE - A cell of a capacitor battery (claimed).    ADVANTAGE - The active substance of battery and active substance of capacitor are aligned to each other respectively, thus improving use rate of the active substance. The cell is prepared using a simple, convenient, practical, and high efficiency method.    DETAILED DESCRIPTION - A cell comprises a layer of cell unit comprising a positive pole sheet, a negative pole sheet, and a membrane (7) between the positive pole sheet and the negative pole sheet. The positive pole sheet comprises a positive pole battery active substance (1), a positive pole capacitor active substance (3), and a positive pole current collecting body (5). The positive pole battery active substance and the positive pole capacitor active substance are respectively coated at two sides of the positive pole current collecting body. The negative pole sheet comprises a negative pole battery active substance (2), a negative pole capacitor active substance (4), and a negative pole current collecting body (6). The negative pole battery active substance and the negative pole capacitor active substance are respectively coated at two sides of the negative pole current collecting body. The cell unit is coiled inwards or alternatively overlapped, pressed, and encapsulated. An INDEPENDENT CLAIM is included for manufacturing the cell.    DESCRIPTION OF DRAWING(S) - The drawing is a sectional view of the cell.
