Embodiment Construction

[0010] Embodiments are described in detail with reference to the accompanying drawings. The nickel-hydrogen button battery is composed of a plate set 9, a conical coil spring 2, a negative cover 1, a sealing ring 4 and a positive steel shell 8. The plate set 9 is made of a connecting piece structure or a single piece structure It consists of a nickel positive plate 7, a hydrogen storage alloy negative plate 5 and a separator 6 arranged between the positive plate and the negative plate. The specific combination method is: (1), first combine the flanging negative electrode cover 1 and the seal ring 4 with snap ring together; (2), put the conical coil spring 2 into the combined seal ring 4 in the direction of the negative electrode cover 1 , and then put the punched gasket or burr gasket 3 on the conical coil spring 2 (whether to put the punched gasket or the burr gasket depends on the battery negative base material); (3), the negative plate 5, the diaphragm 6 Cross-fold with the p

Abstract

The invention discloses a button cell seal ring and a button cell. The technical scheme is as follows: the button cell seal ring is in a single straight body structure with a clamp ring. The button cell comprises the seal ring, wherein the seal ring is in the single straight body structure with the clamp ring. According to the button cell, the double-seal-ring structure is charged into a single-seal-ring structure, the inner space of the button cell is greatly increased so as to create the conditions for enlarging the capacity of the cell under the condition that the external size of the button cell is not changed, and due to a shell of the cell with the structure, the double-connecting-sheet assembling mode can be possibly realized. The reaction area of a positive electrode and a negative electrode is enlarged, and the charge and discharge current density is lowered, so that the conditions for compositing hydrogen and oxygen during the charging the cell are provided, and the inflating problem of the cell caused by large internal charging pressure, and the problem that the button cell can not be rapidly charged can be efficiently solved. Moreover, the efficient space of the cell is enlarged, so that the short circuit ratio is lowered during the assembling of the positive electrode and the negative electrode. The ratio of finished products of the button cells is improved.
