Carbon footprint analysis of lithium ion secondary battery industry: two case studies from China

Through case studies, we confirm the availability of the methodology, and get carbon footprints of the three industry lithium ion secondary battery chains which are 6053.01tCO2eq, 16003.27tCO2eq and 2211.10tCO2eq. Through comparison between the three battery industry chains, we get the conclusion that economies of scale could contribute to the reduction of carbon footprint indirectly and technical improvements may also be helpful. Electric energy consumption is the main factor of lithium ion battery production companies in generating of carbon footprint. This may relate to the main source of China's electric power which is thermal power generation.
