【摘要】 综述了铅酸蓄电池生产中生极板高温固化的机理和作用,以及固化温度对极板固化质量和电池性能的影响,得出采用高温固化的关键是3PbO·PbSO4(3BS)向4PbO·PbSO4(4BS)转化,4BS铅膏的生成和腐蚀层改善了板栅/正极活性物质(PAM)界面的连接性能的结论。提出了采用高温固化工艺后,其它相应工艺(包括正极铅膏中加入添加剂、化成方式等)应该进行调整以及高温固化所应该注意的问题和解决方法。采用高温固化工艺,提高极板固化的温度和湿度,将有效地提高阀控铅酸蓄电池的循环寿命。更多还原

【Abstract】 Mechanism and effect of unformed plate of high temperature curing on the performance of valve-regulated lead-acid（VRLA） battery were elaborated, effect of curing temperature on the curing quality of plates and the performance of batteries were also discussed. Results show that key to use the process of high temperature is conversion of 3 PbO·PbSO₄（3 BS）into 4 PbO·PbSO₄（4 BS）,the formation of 4 BS and corrosion layer, which improve the connection performance of the interface between grid and positive active material（PAM）.The determination that the other technologies should be revised, including paste additive and formation method was suggested; points for attention and solutions to it were summarized at last.Results show that the cycle life of VRLA battery can be improved efficiently by means of improving the curing temperature and humidity.更多还原
