Investigation the effects of mass of active materials of lead-acid battery on active mass utilization coefficient

The lead-acid battery has been widely applied in the fields of electric vehicles, IPS, Solar Power Station etc. due to its advantages of high power, long lifespan, availability of electricity, low cost etc. In this study, 80 pieces lead- acid batteries are adopted to explore the effects of variation of mass of active materials of negative and positive plates on active material utilization co-efficient. Batteries are categorized into four samples according to the mass of active materials of the plates and in every samples has 20 pieces similar batteries of similar plates and active materials. The batteries are charged according to the constant current charging process. After that capacity of the batteries are measured using constant current discharging process. Comparing the capacity found from the research, an optimal combination of plates will be found which will give the best active mass utilization co-efficient.
