Construction of Li-ion battery recycling and carbon footprint management
As of the end of 2023,the number of new energy vehicles in China is 20.41 million,there are a total of 156 comprehensive utilization enterprises that meet the industry standard conditions for review,with a total of 10 468 recycling service outlets established,covering 31 provinces and cities across the country.In 2023,the production of Li-ion batteries exceeds 940 GW· h,and the recycling utilization of spent Li-ion batteries is 225 000 t.It is expected that the recycling utilization of spent Li-ion batteries will exceed 260 000 t by 2024.Regarding industry policy norms and standards,energy consumption indicators for battery production and material production have been proposed,and a preliminary system for the recycling and carbon footprint management of spent Li-ion batteries has been established.Research has shown that the carbon emissions from battery production range from 61 to 106 kg(CO2)/kW·h.Among them,the carbon emissions from production and assembly are between 2 to 47 kg(CO2)/kW·h,while the upstream links(mining,refining,etc.)are 59 kg(CO2)/kW·h,accounting for more than half.
