不発明は酸素サイクル反応による密閉形鉛蓄電池に関す

化している。As is well known, sealed lead-acid batteries that use an oxygen cycle reaction react and absorb oxygen gas generated from regular work during nine-hour periods, and in many cases, the lattice contains lead-calcium, etc. An antimony-free alloy is used, and the electrolyte is either gelled or impregnated into a porous body to make it non-driving.

できない。In a battery with this structure, the moving plate is in contact with a liquid called dilute sulfuric acid and a gas called gas, that is, the three phases of solid and liquid are in contact at once. However, unlike an open type battery in which the elements are buried in dilute sulfuric acid, where the solid and liquid phases are in contact, the influence of gas on the plow plate cannot be ignored.

濃度を測定してその結果を第２図にホす。The concentration of carbon dioxide gas generated during charging was measured for the sealed tube battery using the oxygen cycle reaction according to the present invention, which has this structure, and the conventional battery that has the same structure but does not contain or install a carbon dioxide absorbent. The results are shown in Figure 2.

ない。The charging conditions were IQ hll current for 24 hours and one stitch in a 20-'O atmosphere. In the conventional battery MII, carbon dioxide gas of 5 to 8% by volume is generated, but the battery according to the present invention generates carbon dioxide gas of 1% or less. /(Oh, the carbon dioxide in conventional sealed lead-acid batteries is sl.
The reason why there is a large amount of sand is in the case of T cells, where the amount of hydrogen gas and oxygen gas generated is small due to the sealed reaction, and the amount of sand does not exceed 1% in a typical battery in which the element is buried in a fluid electrolyte.

低下はほとんどみられない。Next, the X battery according to the present invention and the conventional battery were subjected to an intermittent photo-induced parasitic test (II#) in which they were charged and discharged twice and then left at 50° C. for one month after charging. The results are shown in FIG. Conventional batteries show a significant capacity drop after about 12 months, but the uninvented song shows almost no capacity drop during a 15-month trial.

していると帰結できる。The decrease in the capacity of the conventional battery is due to the self-plate, and it can be completely recovered by injecting excessive dilute sulfuric acid and charging.
It can be concluded that this is caused by the difference in the amount of carbon dioxide gas in the space inside the battery.

る。The positive rhythm has a secret structure consisting of a lead-based lattice, such as a ship-carunium alloy, and lead dioxide, which has a strong oxidizing power and is responsible for the electric potential. When dilute sulfuric acid and carbon dioxide gas come into contact with this interface, oxidation of the lattice surface is promoted and a barrier with high electrical resistance is formed, which accelerates the deterioration of the original plate, but this is not the case in the present invention. It is thought that Nagano Life is the result of a barrier forming in the atmosphere where almost no carbon dioxide gas is present.
