Abstract:

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.

Key words: lead-acid battery, process, 4BS
