摘要
Abstract
To research the carbon footprint of lithium manganese batteries throughout their entire life cycle,this article uses the Life Cycle Assessment(LCA)method to calculate and analyze the carbon footprint of a certain type of lithium manganese battery pack.The article quantifies the GHG emissions during the raw material acquisition and processing stage,battery pack production stage,and battery pack sales stage of the product following a"cradle to gate"approach,and calculates the potential contribution of the product to global warming in CO2 equivalent.The carbon footprint of the battery pack's lifecycle was calculated to be 4804.2 kgCO2-eq,with a functional unit GHG emission intensity of 79.8(kgCO2-eq/kWh).The carbon emissions during the raw material acquisition and processing stages are the highest,followed by the product production stage,while the product sales stage contridutes the lowest emission.Finally,suggestions were made for reducing carbon emissions in battery packs based on the calculation results,which can be achieved by controlling carbon emissions from raw materials and increasing the proportion of green electricity used in the production process.关键词
