本考案は鉛−カルシウム合金格子を用いた鉛蓄

信頼型電池を実現するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a lead-acid battery using a lead-calcium alloy lattice, and is intended to realize a highly reliable battery with less self-discharge.

う。 So-called calcium batteries using a lead-calcium alloy lattice have become widely used in recent years because they do not contain antimony inside the battery and have the advantage of little self-discharge. However, lead-calcium alloys have extremely poor mechanical strength compared to lead-antimony alloys, so when used in parts that are subject to external forces such as poles and terminals, a large amount of lead must be used to ensure strength. need to,
This has been an obstacle to making batteries smaller and lighter. On the other hand, when the electrode pole is made of a lead-antimony alloy, although it has excellent strength, antimony dissolves in the electrolyte, albeit in a small amount, and eventually adheres to the surface of the negative electrode plate, increasing the self-discharge of the battery. I get used to it.
本考案はこのような欠点を解消し、軽量で自己

に位置させることにある。 The present invention eliminates these drawbacks and provides a lightweight battery with low self-discharge. A joint made of a lead alloy or lead element that does not contain antimony is arranged between the pole or the terminal, and the pole plate ear and the pole pole or terminal are joined via the joint, and the joint The upper end of the electrolyte is located above the electrolyte level.
以下、本考案を図面に示す実施例によつて詳細

負極板の自己放電が非常に少なくなる。 FIG. 1 is a cross-sectional view showing one embodiment of the present invention, which consists of an ear part 2 of an electrode plate 1 using a lead alloy lattice containing 0.05 to 0.1% calcium and a lead alloy containing 2 to 7% antimony. Polar column 3 and tin 0.5-5%
They are joined by a joint part 4 made of a lead alloy containing. The lower end 5 of the joint 4 is submerged in the electrolyte 6, but the upper end 7 is above the liquid level of the electrolyte 6, so most of the antimony contained in the pole column 3 is dissolved in the electrolyte 6. Therefore, self-discharge of the negative electrode plate is greatly reduced.

つても自己放電が増すことはない。 FIG. 2 is a cross-sectional view showing another embodiment of the present invention, in which a lug 9 of an electrode plate 8 using a lead alloy grid containing calcium is joined to a terminal 10 made of a lead alloy containing antimony by a joint 11 made of a lead alloy containing 0.5 to 5% tin.
The upper end 12 of the terminal 10 is at approximately the same height as the battery container 13. The lower surface of the terminal 10 is covered by the constituent members of the battery container 13. In the embodiment shown in Fig. 1, when the battery is used at an angle or is constantly subjected to vibration, the electrolyte is shaken and the electrolyte is constantly in contact with the electrode post, which may cause antimony to dissolve in the electrolyte. However, in this embodiment, the electrolyte 14 does not come into contact with the antimony in the terminal 10, so that self-discharge does not increase under any conditions of use.

なる。 FIG. 3 is a sectional view showing another embodiment of the present invention, and this embodiment is a so-called retainer type sealed battery in which the separator 15 is impregnated with an electrolytic solution to eliminate fluidity. Although there is no electrolyte level here, in fact, the upper end of the separator 15 can be considered to be the electrolyte level, so the upper end of the joint 16 made of a lead alloy that does not contain antimony is higher than the upper end of the separator 15. If it is, it will exhibit excellent self-discharge characteristics equivalent to the embodiment shown in FIG.

ることも容易である。 As a result of measuring the decrease in capacity when the battery of the present invention having the above structure was left at room temperature, the characteristics shown in FIG. 4 were obtained. Curve A is the capacity of a battery in which the pole or terminal and plate are joined using a conventional lead-antimony alloy, curve B is the battery according to the embodiment shown in Figure 1, and curve C is the capacity of the battery according to the embodiment shown in Figure 2. This shows the trends in each. It is clear from this figure that the self-discharge characteristics of the invented product are clearly improved compared to the conventional product. In addition, in the present invention, even if the same lead-calcium alloy as the grid is used as the lead alloy of the joint, the effect of reducing self-discharge is the same. Furthermore, the structure of the present invention can be easily applied not only to the joints between the electrode plates and the terminals or pole columns, but also to the intermediate balls used to connect cells.
