するものである。[Detailed description of the invention] (a) Industrial application field The present invention relates to a storage case for a lead-acid battery, in which a battery is stored with an impedance element connected between the cathode and anode external terminals of the lead-acid battery. It is related to.
(ロ) 従来技術
鉛蓄電池、特に遊離の電解液が存在しないよう
に電解液を制限した形体のいわゆるリテナー式鉛

用するまでの間、定期的に、例えば６ケ月毎に望
ましくは３ケ月毎に、補充電をし、常に満充電に
近い状態で保存することが必要とされている。(b) Prior art Lead-acid batteries, especially so-called retainer-type lead-acid batteries in which the electrolyte is restricted so that no free electrolyte exists, are subjected to chemical conversion treatment after battery assembly, and shipped fully charged or Until the battery is stored and actually used, it is necessary to replenish the battery periodically, for example every 6 months, preferably every 3 months, and store it in a nearly fully charged state at all times.
このことは、鉛蓄電池が平均的に見れば１日あ

酸鉛（PbSO4）が不活性化し、その結果充電効率
が悪くなつて容量が十分回復されず、電池特性の
低下を招くため、補充電を繰り返して保守をする
必要がある。 This means that on average, a lead-acid battery self-discharges about 0.1 to 0.15% of its battery capacity per day, and after six months, the battery capacity decreases due to self-discharge of about 20 to 30%. i.e. 20-30%
is discharged. If the discharge products discharged by this self-discharge are activated by charging, in other words, if the battery capacity is restored,
Although it is not necessary to perform supplementary charging frequently, if the battery is left in this self-discharge state for a long period of time, lead sulfate (PbSO 4 ), a discharge product, becomes inactivated, resulting in poor charging efficiency and insufficient capacity recovery. First, battery characteristics deteriorate, so maintenance must be performed by repeatedly performing supplementary charging.
しかし、この保守作業は煩瑣であるばかりか、
たとえ、補充電を繰り返しても、電池容量は完全
に回復しないなどの問題点があつた。 However, this maintenance work is not only troublesome, but also
Even if supplementary charging was repeated, the battery capacity did not fully recover.

ない鉛蓄電池の保存方法を先に提案した。 As a result of various studies, the inventors of the present invention have found that by connecting an impedance element between the negative and anode terminals, the PbO 2 corrosion layer on the current collector surface is prevented from converting into an inactive PbSO 4 layer during storage. We discovered this and proposed a method for preserving lead-acid batteries that does not cause deterioration of battery characteristics even after long periods of storage.

電池特性の低下を防止することが可能となる。 This means that if the corrosion layer of PbO 2 formed on the surface of the anode current collector due to chemical charging is stored in an open circuit state, if left for a long period of time, it will turn into Pb ++ ions, and this Pb + The + ions react and combine with the SO 4 -- ions remaining in the electrolyte to form an inert
Four layers of PbSO are generated, which causes a voltage increase during charging after storage, resulting in charging failure. On the other hand, if the device of the present invention is left with the negative and positive poles connected to an impedance element, the discharge current will flow in response to the discharge voltage due to the load connection, resulting in a minute current discharge at the end of the discharge. Therefore, the discharge of the active material is completed evenly around the surface of the electrode plate while the discharge of the active material is progressing, and most of the SO 4 -- ions remaining in the electrolyte are consumed, so the PbO 2 of the current collector in the corrosion layer
Since the generation of PbSO 4 caused by Pb ++ and SO 4 -- is suppressed, the PbO 2 corrosion layer that occurs due to long-term storage is suppressed.
Even after long-term storage, it shows an effective effect on charging, especially constant voltage charging, without causing the problem of deterioration of charging current carrying performance due to PbSO 4 conversion.
It becomes possible to prevent deterioration of battery characteristics.
