Abstract

Positive grid corrosion is one of the major causes of lead-acid battery performance failures. This phenomenon occurs slowly under normal conditions, so that any modifications of the grid design should be undertaken only after an extended testing period. It is very desirable to accelerate simulated battery life in order to obtain data on the status of corrosion, to correct problems, and ultimately to improve the battery service life. Tests in the technical literature are discussed where temperature is used to accelerate corrosion and growth. It has been confirmed that corrosion phenomena accelerate as temperature increases and that this increase is, in the case of lead calcium alloys, proportional to the square of the number of test days. Some results of the FIAMM grid testing program are offered for evaluation and discussion. FIAMM has made significant changes to the positive grids used in its Monolite series of valve-regulated lead-acid batteries. The type-S grid has been redesigned by increasing the cross-section areas of several of the horizontal and vertical ribs, which has increased the grid weight.<>

栅格设计变量对阀控备用电池的影响

正极栅腐蚀是铅酸蓄电池性能失效的主要原因之一。在正常情况下，这种现象发生缓慢，因此，对电网设计的任何修改都应在延长测试期后进行。为了获得有关腐蚀状态的数据，纠正问题，并最终提高电池的使用寿命，加速模拟电池寿命是非常可取的。技术文献中讨论了使用温度来加速腐蚀和生长的试验。已经证实，腐蚀现象随着温度的升高而加速，并且在铅钙合金的情况下，这种增加与测试天数的平方成正比。给出了FIAMM网格测试程序的一些结果，以供评价和讨论。FIAMM对其Monolite阀控铅酸电池系列中使用的正栅极进行了重大更改。s型网格经过重新设计，增加了几个水平和垂直肋的横截面面积，从而增加了网格重量。
