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
