っていない。Conventional technology Lead-antimony based alloys have been used for the grids of paste-type electrode plates used in lead-acid batteries, but lead-calcium based alloys are increasingly being used due to the demand for maintenance-free batteries. It's here. Using a lead-calcium alloy for the grid has advantages such as less self-discharge of the battery and less loss of electrolyte, eliminating the need for water replenishment. A serious drawback, which was not observed with antimony-based alloys, was an early decline in battery capacity. This is said to be caused by the formation of a poor electrical conductor between the grid and the active material during charging and discharging of the battery. Twelve various proposals have been made to solve this drawback, but the problem has not yet been solved.

The purpose of the present invention is to provide a paste-type lead-acid battery that is unlikely to experience early capacity loss even after repeated use.

下はみられなかった。In this example, strength soap was used as the potassium salt of higher fatty acid. First, dissolve the potash soap from the specified area in purified water, then VIiI! An electrolytic solution having a specific gravity of 1.20 was prepared by adding an acid. This electrolyte was used for a car carrier with a nominal capacity of 11 sAh (5 hR), which was made of a lead-calcium alloy for both the construction type and the negative electrode.
Pour the liquid into the TX pond and add 300% to the theoretical capacity of the positive electrode active material.
The first charge was performed with % electricity. For comparison, a conventional product was also subjected to the next test, in which an electrolytic solution without the addition of potassium salts of higher fatty acids was injected and initial charging was performed under similar conditions. Is the exam complete? ! After adjusting the electrolyte specific gravity to 1.28,
The test results are shown in Figure 1 by repeating the charging and discharging pattern of discharging to 1.75V/cell with a 5hR current (to 5 and 6), and charging after discharging to 130% of the discharge capacity in 10 hours. show. In the figure, A is a conventional product in which no potassium salt of a higher fatty acid is added to the electrolyte, B and C are a conventional product in which a potassium salt of a higher fatty acid is added to the electrolyte, and potassium soap is added to the electrolyte at 0.1Q/Q and 0.5, respectively. ri/l (K″′
This is the product of the present invention in which 57 mg/immune and 284 mQ/λ) were added. The capacity of the conventional product decreased with each cycle, and after 10 cycles, the capacity was less than 50% of the initial capacity. On the other hand, products B and C of the present invention showed little decrease in performance due to charge/discharge cycles, and no early capacity decrease peculiar to calcium batteries was observed.

It was effective within the range of mgZ.
