Abstract

PURPOSE:To prevent any deterioration of the performance of a lead storage battery without requiring any maintenance by fixing the battery to the raised pieces of a base plate and joining the electrode plates together through impedance connection by means of a chip resistance and a print pattern formed on one of the raised pieces. CONSTITUTION:A positive and a negative plate 4b and 4a, current collectors 2 and 3 and a separator 5 are installed in a box-like body 1 with terminals 6 and 7 exposed so as to assemble a retainer-type battery (A) in which the amount of electrolyte is restricted so that any liberated electrolyte does not exist. Next, a base plate 8 consisting of vinyl chloride or the like and having raised pieces 9, 10a, 10b and 10c on its four sides is prepared, and the battery (A) after being subjected to formation charging is fixed to the base plate 8 by means of elastic pieces 16-18. At the same time, the terminals 6 and 7 are joined together through impedance connection by means of a chip resistance 11 and a print pattern 14 formed on the raised piece 9. After that, the thus obtained body is airtightly sealed by covering the entire body with a styrene resin. By the means mentioned above, the battery (A) can be preserved over a long period of time without performing any auxiliary charging or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a method for storing a lead-acid battery, particularly a so-called retainer-packed lead-acid battery in which the amount of electrolyte is limited so that no free electrolyte is present. The purpose is to provide a storage method that does not cause deterioration of battery characteristics even if left for a long period of time.

(b) The conventional retainer set battery limits the amount of electrolyte and makes the eye-cathode capacity about 10 to 30% larger than the anode capacity so that the anode becomes fully charged first during charging to prevent overcharging. In this case, the cathode absorbs and consumes the oxygen generated from the anode.

Normally, this type of battery is subjected to chemical conversion treatment after battery assembly, and is shipped or stored in a fully charged form, and is periodically used, preferably every 6 months, until it is actually used.
It is necessary to replenish the battery every month and store it in a state close to fully charged.

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 6 months, it self-discharges about 20 to 30% of its capacity. decreases. That is, 20 to 30% was discharged. If the discharge products discharged by this self-discharge are activated by charging, in other words, if the battery environment recovers, there is no need for frequent supplementary charging, but if it is left in this self-discharge state for a long time, , lead sulfate (PbSO4), which is a discharge product, becomes inactivated, resulting in poor charging efficiency and insufficient recovery of 4H, leading to deterioration of battery characteristics, which requires repeated supplementary charging for maintenance. There is.

However, [2] This maintenance work was not only complicated, but also had the problem that even if supplementary charging was repeated, the number of customers would not fully recover.

According to studies by the present inventors, if the battery is left unattended after chemical charging treatment, the battery voltage will gradually decrease due to self-discharge. Lead dioxide on the surface of the current collector (

O4-- ions chemically combine to form PbSO4, and if left for a long period of time, this PbSO4 tends to become inactive, resulting in poor charging efficiency during recharging and insufficient recovery of capacity. , resulting in deterioration of battery characteristics. These phenomena deteriorate as the period of the auxiliary charge cycle becomes longer, that is, as the period of time the battery is left unused becomes longer, and the deterioration of these phenomena becomes even more accelerated when the battery is left unused in a high-temperature atmosphere.

H → Purpose of the Invention The present invention aims to provide a method for storing lead-acid batteries in which the battery characteristics do not deteriorate without requiring complicated maintenance to maintain the battery characteristics through repeated supplementary charging.
