Abstract:

A precise estimate of recovery potential and spatial distribution of lithium minerals in China’s new energy passenger vehicles can ensure a fast growth of China’s new energy vehicle industry and lithium resource supply security. This paper, based on China’s new energy passenger vehicles production and market data, uses their unit power storage, battery types, unit power storage lithium use intensity, lithium battery life span to estimate lithium stock and recovery potential of China’s new energy passenger vehicles. The results show a fast rising trend of lithium stock and recovery potential of China’s new energy passenger vehicles in recent years, up to 22 kt of lithium stock in China new energy passenger vehicles by 2021, but their recovery potentials will not be at the same pace recently and in the near future, only reaching up to 730 t in 2021. In 2021, Beijing-Tianjin-Hebei, Yangtze River Delta, Zhu River Delta contributed 60% of lithium recovery potentials nationwide, 18 cities including Beijing, Shanghai and Hangzhou hold 73% of lithium recovery potential nationwide. Lithium stock and recovery potential of new energy passenger vehicles show a concentrating to scattering trend spatially in recent five years. This paper presents suggestions on globally developing lithium resource, boosting lithium research and industrialization and making regional lithium battery recovery system.

摘要: 为保障新能源汽车产业快速发展和锂资源供给安全,当前亟须准确掌握、测算新能源汽车锂电池的锂回收潜力及其空间分布。论文利用中国新能源乘用车生产大数据、消费大数据,综合考虑新能源乘用车单位车辆储电量、装配锂电池类型结构、单位储电量锂消费强度、锂电池使用寿命等动态数据,测算新能源乘用车上的锂库存和锂回收潜力。结果显示:1)近年来中国新能源乘用车上的锂库存和锂回收潜力呈现快速增长的趋势,截至2021年蓄积在新能源乘用车上的锂库存已经超过2.2万 t,但短期内新能源乘用车的锂回收潜力规模并不大,2021年新能源乘用车的锂回收潜力仅有730 t;2)新能源乘用车上的锂库存和锂回收潜力主要集中在重点地区和重点城市,2021年京津冀、长三角、珠三角地区贡献了全国60%的锂回收潜力,京沪杭等18个城市的锂回收潜力占全国总体锂回收潜力的73%;3)近5年,新能源乘用车的锂库存和锂回收潜力在空间上呈现出从集中走向分散的特征。
