Effects of Microstructures of Active Material on Performance of VRLA Battery
- 2015年第21卷 
通过SEM、XRD检测不同工艺条件下的生极板及活极板组分，并对不同组分的极板进行不同倍率的放电检测及循环检测. 结果表明，极板的制作工艺和化成过程工艺影响极板化成后α-PbO2和β-PbO2含量及结构，从而影响蓄电池的性能，是4BS（四碱式硫酸铅）技术应用过程中的关键控制点. 4BS技术的应用为蓄电池薄极板化、深循环、长寿命等提供了技术基础.The structure, morphology and content of the as-prepared and the processed samples were characterized by the means of SEM and XRD. The discharge capacities and cycle life performances of the as-prepared and the processed samples were tested by electrochemical measurements with different rates. The results indicated that the 4BS technology which can affect the plate design, deep cycle capability and cycle life is a basic technology for the VRLA batteries. It was also confirmed that the contents and structures of α-PbO2 and β-PbO2 formed with different processing conditions can affect the performance of the VRLA batteries, suggesting that the production and formation of plates are the key control points of 4BS technology.
