However, the bending lead-platinum electrode plates have an extremely high specific gravity, which makes the storage battery heavy, and the high electrical resistance causes large voltage drop during charging and discharging, resulting in poor battery performance.

Furthermore, in this case, there is a new issue raised, namely, the original aluminum and lead IL;
This problem has been achieved by overcoming the problem that it is difficult to properly join and integrate them as a composite material because they do not fuse with each other.

It is characterized in that a lead covering layer is integrally formed on the outside of a covering layer made of a high-quality metal. Another invention relates to a preferable method for manufacturing the composite material as described above, including the step of coating the surface of an aluminum core material with a metal that has good wettability for both aluminum and lead by hot-dip plating. and,
This method is characterized by a step of forming a lead enveloping layer by further encasing the surface of the enveloping layer with lead.

る点で好ましい。The above-mentioned metals that have good wettability with both aluminum and lead are metals that easily fuse or diffuse with aluminum and lead to form an alloy with them. Specific examples thereof include tin, tin-zinc alloy, and tin-zinc alloy. Examples include antimony alloys and tin-lead alloys. Among these, the use of tin and tin-zinc alloys is particularly preferable because it provides even better results, that is, it is possible to form a coating layer in a strong bonded state without defects such as pinholes on the surface of the aluminum core material. .

クスの活性化温度まで予熱することが必要である。Further, as the means for coating the metal, any known plating method such as hot-dip plating, thermal spraying, sputtering, and ion blasting can be employed, but hot-dip plating is particularly preferred. That is, according to the hot-dip plating method, a dense metal coating layer can be formed on the surface of the aluminum core material, the adhesion between the two is also good, and a strong metal-to-metal bonding state can be obtained with an alloy layer formed at the interface. When using this hot-dip plating method, it is necessary to use flux to remove the oxide film on the surface of the aluminum core material, and in this case, it is also necessary to preheat the aluminum core material to the activation temperature of the flux. be.

It may also be used to form a

Preheating to about 200'C (preferably). If lead is cast without this preheating or when the preheating temperature is too low, the lifting will be poor and the bonding interface with the metal coating layer will deteriorate. The wettability of lead deteriorates, making it impossible to obtain a good bond.

、それらの良好な接合状態を実現したものとなしうる。The above-mentioned composite material of aluminum and lead according to the present invention has aluminum as the core material and the outside is covered with lead, so it is a good electrical conductor and can be used as an electrode plate for lead-acid batteries. Not only can it be suitably used as a terminal side, but in particular, the presence of an aluminum core material with a low specific gravity can significantly reduce the weight of lead-acid batteries, and the electrical resistance of the aluminum core material can be reduced. Since it is small, it is possible to improve the performance of lead-acid batteries by preventing voltage drops during charging or discharging. Of course, since the above composite material is made by joining an aluminum core material and lead through a coating layer of a metal that has good wettability to both aluminum and lead, it is difficult to join aluminum and lead. Even though it consists of a concavity in combination with lead, it is possible to realize a good bonding state between them.

It is possible to obtain a composite material having excellent electrical properties, in which the lead coating layer and the lead coating layer are firmly metal-bonded with good adhesion through the coating layer.
