、近年ハンドクリーナ用の電源、■
’ＭＴＲ用電源等での需普が急増し、今後も家電品への
応用が増加するものと考えられる。Conventional technology Conventionally, small sealed lead-acid batteries have been so-called maintenance-free, do not leak electrolyte, and can be used freely and universally, so in recent years they have been used as power supplies for hand cleaners, MTR power supplies, etc. The demand for these products is rapidly increasing, and it is thought that their applications in home appliances will continue to increase in the future.
ところで、上記の如く、ハンドクリーナや［ＴＲさらに
家電品の電源として小型密閉式鉛蓄電池が使用された場
合、一般に過放電後放置すると。By the way, as mentioned above, when a small sealed lead-acid battery is used as a power source for a hand cleaner or other home appliance, it is generally left unattended after being over-discharged.
充電が入り難く、容量が回覆し難い欠点を有している。It has the disadvantage that it is difficult to charge and it is difficult to reverse the capacity.
これは小型密閉式鉛蓄電池に顕著な３Ａ象であり、他の

りみられぬ現象である。This is a 3A phenomenon that is noticeable in small sealed lead-acid batteries, and is a phenomenon that is rarely seen in other secondary batteries, such as nickel-cadmium batteries.

回復性の欠点が不具合Ｉこ直接むすびつく原因となる。For this reason, it is said to be a fatal drawback of small sealed lead-acid batteries. In particular, when applied to home appliances, since they are used by unspecified users, shortcomings in charging performance and capacity recovery performance after being left for overheating can directly lead to problems.

いため合金の均一性ｌこ難がある。Problems to be Solved by the Invention By the way, the cause of this problem is that when a small sealed lead-acid battery is over-discharged and left unattended, the gap between the lattice on the anode plate and the active material (this is non-conductive lead phosphate). It is thought that a high resistance layer is formed.As a countermeasure, changing the alloy composition of the anode lattice body is being considered.Various alloy compositions have been considered so far, but The ions leaked out of the electrolyte and had an adverse effect on the cathode plate.
2 The price has increased +1. Due to poor castability and productivity problems, no alloy with satisfactory improvements in over-discharge storage characteristics has been developed. At one time, lead-silver alloys attracted attention, but they had poor productivity in terms of mechanical strength, and the high melting temperature of silver caused problems with the uniformity of the alloy.
問題点を解決するたぬの手段

ため光放電サイクルの進行にともない基体が腐食しても
効果が存続し得る。By depositing a thin film of Au on the active anode substrate, even if a high-resistance layer is formed due to lead acid after overdischarge, the presence of Au will reduce the local electrical resistance of the substrate-Au-active material. The bus can be reshaped, easily charged, and capacity recovery improved. Furthermore, since Au is stable even in acidic and oxidizing atmospheres, it continues to exist even if left for a long period of time. The solid solubility of the aluminum alloy and the base alloy lead is extremely high, and no peeling of the evaporated N film (such as substrate force) is observed, and it gradually diffuses into the interior of the matrix, allowing the progress of the photodischarge cycle. The effect can persist even if the substrate corrodes.

It is dispersed in one place and its thickness is about 0.05 μm. This vapor-deposited substrate was filled with a conventional paste, and an anode plate was attached using a conventional method. A battery having two anode plates and three cathode plates was prepared and subjected to the following over-discharge storage characteristics test. The battery is a sealed type, and the electrolyte has a sulfuric acid specific gravity of 1.3.

A 240++qA discharge was performed at 0°C to confirm the initial capacity. Thereafter, the battery was charged at a constant voltage of 2.45 V, photoelectrically charged for λ8 hours, and then subjected to constant resistance discharge using a resistance of 5 Ω for 5 consecutive days. Thereafter, it was left in an atmosphere at 45° C. for 30 days, and charged at a constant voltage of 2.45 V for 8 hours. After the photovoltaic cycle was completed, a 240 mA discharge was performed at 20°C and compared with the initial value. The drawings show the capacity recovery rates of battery A according to the present invention and conventional battery B. As a result, it can be seen that the capacity recovery rate of battery A according to the present invention is higher than that of conventional battery B.
