The leakage of sulfuric acid was the main environmental risk of lead-acid batteries in the process of production, processing, transportation, use or storage. According to the project scale the sulfuric acid leakage rate was calculated to be 0.190kg/s, and the leakage amount in 10 minutes was about 114kg.
Nevertheless, the leakage of emerging materials used in battery manufacture is still not thoroughly studied, and the elucidation of pollutive effects in environmental elements such as soil, groundwater, and atmosphere are an ongoing topic of interest for research.
Lead acid batteries and vanadium redox batteries may vent hydrogen gases, from the sulphuric acid electrolyte. The acid electrolyte is extremely corrosive and can cause serious human injuries. Sodium-based batteries operate at high-temperature ranges (270–350 °C) and contain reactive metal sodium in a molten state.
According to the World Health Organization (WHO), today around 85% of the world’s lead consumption is for the production of lead-acid batteries. The good news is that lead-acid batteries are 99% recyclable. However, lead exposure can still take place during the mining and processing of the lead, as well as during the recycling steps.
Thus, while the 99% recycling statistic is important, it may understate the potential for lead contamination via this process. However, the situation would definitely be much worse if these batteries were being landfilled, as a single lead acid battery in a landfill has the potential to contaminate a large area.
