蓄電池正板柵變形與腐蝕板柵腐蝕速率與合金的組成、微觀結(jié)構(gòu)、電極電勢、電解液組成、工作溫度及極板蠕變有關(guān)。此外與使用儲運有關(guān)，比如儲存溫度越高，電池正板柵腐蝕加劇，儲存時間越長，板柵腐蝕層厚度增加，深放電次數(shù)頻繁則正板柵腐蝕嚴重，浮充電流與電壓增大，對正板柵腐蝕也加速。隨著板柵的腐蝕加劇，會發(fā)生板柵變形，使板柵抗張強度減少，板柵本體減薄，腐蝕層加厚，電阻增大，放電受阻，還可能導致短路。
The storage battery positive plank grid transforms with decay the plank grid decay constituting of velocity and metal alloy, tiny view structure, electrode to give or get an electric shock power, electrolyte to constitute, work temperature and pole the plank Ru become relevant.In addition have something to do with using keeping a luck, for example store temperature more high, the battery positive plank grid corrosion turns worse and store time more long, the plank grid corrosion layer thickness increment, deeply turn on electricity number of times multifarious then positive plank grid decay severity, float to refresh to flow to enlarge with electric voltage, to positive plank grid decay also acceleration.Because the corrosion of plank grid turns worse, will take place the plank grid transform and make the plank grid decrease of strength anti- piece, the plank grid essence reduces thin, decay a layer to thicken, the electric resistance enlarges and turns on electricity to be blocked, may also cause short circuit.
