工数の増加をもたらすという欠点があった。Conventional technology and its problems Recently, in order to prevent self-discharge and gas generation at the end of charging, and to improve deep discharge cycle life, a positive electrode plate using a grid made of a lead-antimony alloy with low antimony content was developed. A so-called hybrid battery, a lead-acid battery equipped with a lead-acid battery and a negative electrode plate using a grid made of a lead-calcium alloy, has come into use. Conventionally, the additional lead used to form the joints of this hybrid battery contains 2 to 4 antimony.
A lead-antimony based alloy with good weldability, which is composed of 0.05 to 0.2 weight % arsenic and the balance lead, is used. However, in this case, it is known that when adverse conditions such as high temperature and overcharging occur, abnormal corrosion occurs in either the negative electrode plate or the pole for drawing out the current. 5j to eliminate this drawback! As shown in JP-A-60-125867, it has been proposed to use a lead alloy that does not contain antimony as the additional lead, but when it does not contain antimony, weldability with the electrode plate is very poor. There were cases where the electrode plate came off from the lead (connection part). Furthermore, since the fluidity is reduced, welding operations require a high degree of skill and the number of assembly steps increases.

Lead-acid battery 1 used a positive electrode plate using a lattice body made of a lead-antimony alloy and a lattice body made of a lead-calcium alloy. The electrode plate group 2 includes a negative electrode plate, and a connecting portion 4 made of a lead-antimony alloy is arranged between the electrode plate group 2 and a pole post 3 made of a lead-antimony alloy. Further, as the electrolytic solution 5, a normal flowing electrolytic solution is used.

Eight 20 HR, 67 monoblock lead-acid batteries were prepared, and a two-way configuration test was conducted.

表に示す。The test method was discharging 125AX for 4 minutes at a temperature of 75℃, and charging i1.
One cycle is 4.8V x 10 minutes, 510 m discharge is performed for 50 seconds every 480 cycles, and the discharge end voltage is 7.2
In this method, the life is determined to be the time when the temperature reaches v or less. Results first

制するものと思われる。No abnormal corrosion was observed in the area enclosed by hatching in Table 1. This is thought to be because tin entered between antimony and calcium and prevented contact between the two. In addition, as a result of the test, abnormal corrosion occurred when the amount of arsenic in the adder increased, so it seems that the increase in arsenic suppresses the effects of tin.
