Patent JP-H1186896-A (JP)
Title: Alkaline storage battery
Inventor: IIDA TAKUMA
IPC: H01M50/528
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of the reactivity of a negative electrode at low temperature and to improve a large-current discharge characteristic at the low temperature by making the number of spot weld points between a plate-like current collector and a pole plate tip larger on the negative electrode side than on the positive electrode side. SOLUTION: The discharge capacity and discharge voltage of a battery setting the number of weld points of a negative electrode current collector 5b equal to or larger than that of a positive electrode current collector 5a are increased, as compared with those of a battery which sets the number of weld points of the negative electrode current collector 5b smaller than that of the positive electrode current collector 5a. When the number of weld points on the negative pole plate side is made smaller than that on the positive pole plate, the reactivity of a hydrogen storage alloy is deteriorated.  When the number of weld points on the negative pole plate side of the battery is made larger than that on the positive pole plate side, since the electrode resistance is not increased or its increase is small, only the reactivity of the hydrogen storage alloy itself practically affects the reactivity of the negative electrode, and the effect on the discharge characteristic is reduced. The ratio between the number of the weld points of the positive pole plate tip and the plate-like current collector and that of the negative pole plate is preferably set to 1:1.2 to 1.6.
