The aluminum casing is primarily used as a housing for capacitors in industries such as new energy vehicle charging stations, photovoltaic inverters, 5G base stations, industrial frequency converters, servers, and power adapters, with an average weight of approximately 2.4 g and an average diameter of about 22.5 mm. The dataset includes main raw and auxiliary materials, energy inputs, atmospheric emissions, and waste outputs from the production process; however, infrastructure such as manufacturing of production equipment and construction of factory buildings are excluded from the system boundary. The life cycle inventory is compiled from data sourced from multiple references. The production of aluminum casings for aluminum electrolytic capacitors involves processes including material mixing, stamping, cleaning, and inspection.
