Along with communication, energy storage field development, valve controlled sealed lead-acid accumulator uses in hot environment more and more.Such as the communication base station of city roof, under the hot conditionss such as the telecommunications repeater, rural area of south China, outdoor wind and solar energy stored energy application.The valve controlled sealed lead-acid accumulator that prior art is produced is applied in above-mentioned hot environment, and the life-span can shorten more than 50%.Chief component thing by the active matter formula of existing negative pole is as follows: lead powder, fiber, sulfuric acid, deionized water, lignin, humic acid, acetylene black etc.Negative electrode active material conventional formulation exists acceleration dehydration and contraction to cause shorter battery life.
Summary of the invention
The object of this invention is to provide the valve controlled sealed lead-acid accumulator negative electrode active material that can adapt under applied at elevated temperature condition, reduce dehydration, improve the contraction of negative plate.
High temperature valve controlled sealed lead-acid accumulator negative electrode active material of the present invention, comprises lead powder, sulfuric acid, water, short fiber, lignin, humic acid, acetylene black, indulin and anisaldehyde.
As improvement, indulin, anisaldehyde with respect to the percentage by weight of lead powder quality are: indulin 0.1%～0.5%, anisaldehyde 0.1%～0.6%.
The present invention also provides a kind of high temperature valve controlling sealed lead-acid battery negative pole plate, by grid full-filling lead plaster, is made, and described lead plaster is above-mentioned negative electrode active material.
The interpolation of indulin, anisaldehyde can reduce self-discharge of battery, delays negative pole sulfuration, extend the negative pole life-span.The battery dehydration that adopts negative electrode active material of the present invention to make pole plate assembling significantly reduces, and self-discharge of battery is little, can delay negative pole sulfuration and contraction, extending battery life, meets the demand under hot conditions, put forward the applied at elevated temperature performance of high storage battery.

Cathode lead plaster prepared by above-described embodiment is for making specification 2V500Ah battery: use positive plate, negative electrode grid, the electrolyte of this area routine, the present invention is not particularly limited this.The full-filling of gained cathode lead plaster, on negative electrode grid, is formed to negative plate after the dry processing of overcuring; By 10 of positive plates, 11 of negative plates, 22, dividing plate, positive/negative plate is respectively with forming pole plate group according to the negative, positive mode lamination replacing after dividing plate parcel, pole plate group's positive plate lug and Positive Poles pole are welded into one, form positive bus, and pole plate group's negative plate lug and negative pole pole pole are welded into one, form negative bus-bar, so just formed the battery electrode group of a 2V500Ah; Pack above-mentioned utmost point group into battery case, vacuumize quantitative perfusion electrolyte in battery, proceed to and be internalized into charging.
Battery prepared by above-described embodiment carries out high temperature and accelerates float life test, test procedure is: storage battery is positioned in the environment of 60 ± 2 ℃, with 2.25V/ monomer float charge voltage trickle charge 30 days, storage battery is taken out, in the environment of 25 ± 2 ℃, carry out 3 hour rate discharge examination, for once circulation, until battery capacity lower than 3 hour rate rated capacities 80% time, life test finishes.
The sample storage battery sampling of producing by embodiment mono-is accelerated float life test method by high temperature and is carried out floating charge circulation, until storage battery 3 hour rate discharge capacities lower than rated capacity 80% time, the cycle-index of sample battery is 10 times, and the storage battery cycle-index of prior art generally only has left and right 5 times.
The sample storage battery sampling of producing by embodiment bis-is accelerated float life test method by high temperature and is carried out floating charge circulation, until storage battery 3 hour rate discharge capacities lower than rated capacity 80% time, the cycle-index of sample battery is 9 times, and the storage battery cycle-index of prior art generally only has left and right 5 times.
From above-mentioned result of the test, can illustrate, the storage battery that adopts the inventive example to make, high temperature float life obviously improves, and can adapt to the use under hot environment.
