Risk Assessment of Lithium Resource Supply in China Based on Material Flow Analysis
Based on the material flow analysis framework,the paper conducts a risk assessment system for China's lithium resource supply in four stages:production,processing and manufacturing,use,and waste management.Besides,the paper evaluates the risk of China's lithium resource supply from 2011 to 2022.The results indicate that from 2011 to 2022,China's lithium resource supply risk showed a steady decline within the medium-risk range,among which the domestic supply capacity in the production stage is limited,and the supply risk shows an upward trend;in the processing and manufacturing stage,the supply of lithium salt is sufficient and has technological advantages,so the supply risk has decreased;the use stage is complexly influenced by consumption stimulation,industrial policies,product quality,substitutability,and technical factors,the fluctuation of the risk value is not significant;in the waste management stage,the Value-at-Risk has decreased significantly affected by eco-social development and the increased recovery rate.Based on the results of the study,it is recommended to establish a dynamic assessment mechanism of lithium resource supply risk in accordance with China's actual situation,improve lithium resource security and production and supply capacity,strengthen all-round technological innovation in the lithium industry chain,and improve relevant industrial policies to reduce the risk of lithium resource supply in China.
