本発明は電池の劣化状態を指示する機能を持った密閉形
鉛蓄電池に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealed lead-acid battery having a function of indicating the state of deterioration of the battery.
密閉形鉛蓄電池はゲルまたは多孔体などの保液体を用い
て電１ｌＩｌ液を非流動化し、酸素サイクルの密閉反応
によって電解液の水の□減少を防いでいる。Sealed lead-acid batteries use a retaining liquid such as gel or porous material to make the electrolyte non-fluid and prevent the water in the electrolyte from decreasing due to the sealing reaction of the oxygen cycle.

二がって緊急時に充分な放電性能を期待するためには、
保液体の乾湿状態を随時測定して電池性能の劣化程度を
管理する必要がある。However, even if a small amount of hydrogen gas is generated due to neglect, float charging, charging/discharging, etc., the water will gradually be lost and the retained liquid will dry out. When this exceeds a certain limit, the internal resistance becomes significantly high and the discharge performance deteriorates. Shif
Second, in order to expect sufficient discharge performance in an emergency,
It is necessary to monitor the degree of deterioration of battery performance by constantly measuring the dry and wet state of the liquid retaining liquid.

Measure the voltage between 1iM +61 and (71,
In the instructing circuit, (10) is the exhaust section. Note that the wet state changes depending on the dryness and humidity of the strap and pole. As shown in FIG. 2, the relationship between the change in the wet state and the electrical resistance increases significantly when the volume ratio of dilute sulfuric acid to the pore volume of the porous body reaches 0.07 and dries further. Note that FIG. 2 shows the case of a glass fiber mat having an average diameter of 0.5 μm as the porous body, and the case of a porous sheet made of polyethylene and fine silica powder.
