摘　　要：首先,采用排除法找出了密封电池安全阀正压形成的原因在于极板浸渍硼酸。然后,通过定量试验测量到,在多种条件下,在电池内部析气量和析气速率的变化趋势。同时,对浸渍硼酸与不浸渍硼酸的极板进行了比较。试验结果表明,采用浸渍硼酸溶液的防氧化处理工艺后,电池在静置期间内部不断产生气体,从而引起安全阀形成正压。最后,对析气的机理进行了分析。At first, the positive pressure of the safety valves of sealed batteries because of boric acid impregnating the plates was found by using the method of elimination. Then, the variation trend of gas volume and gas evolution rate in the batteries was measured by quantitative test under various conditions. At the same time, the plates impregnated with boric acid were compared with that not impregnated with boric acid. The results showed that if the oxidation resistant treatment process of plates impregnated with boric acid solution was adopted, the gas was continuously produced inside the battery during the store period, thus causing the positive pressure of the safety valve. Finely, the mechanism of gas evolution was analyzed.
