“…1,2 Among present various battery technologies, lead-acid (PbA), nickel-metal hydride (NiMH), nickel-cadmium (NiCd), and lithiumion (Li-ion) are the major chemistries toward different applications due to their specific characteristics related to energy density, power density, durability, and economic feasibility. [3][4][5] Despite the growing popularity of Li-ion and NiMH batteries, the demand for PbA batteries grows proportionately due to their ease in availability, manufacturing, maintenance, reliability, recycling, and cost. 6 Lead-acid battery demand is higher in large-scale applications such as renewable energy storage systems, that is, wind and solar technologies, despite having lower energy density (<50 Wh/kg).…”
