Abstract:

In order to improve the capacity and life of tubular cathode for lead-acid battery,by setting different impregnation acid concentration and curing temperature,a series of tubular cathode for lead-acid batteries were prepared by mixing,powder filling,acid impregnation,curing and chemical processes,and assembled into small batteries with negative plates with excess capacity.The effects of leaching acid concentration and curing temperature on the content and morphology of 4BS in raw plate and the capacity and life of cooked plate were investigated,and the reasons were analyzed from the micro level by means of XRD and SEM.The results showed that too high or too low concentration and curing temperature were not conducive to improving the capacity and life of the cathode of lead-acid battery.Finally,the best comprehensive performance including capacity and life of the tubular cathode for lead-acid battery was determined as follows:the leaching sulfuric acid proportion was 1.1 g/cm3 and the curing temperature was 60 ℃.
