国际能源署(IEA)2022年7月发布了一份题为《全球电动汽车电池供应链》的专题研究报告,本刊摘其要点介绍如下。
一、电动汽车电池和供应链
(一)电动汽车电池需求量在2021年翻了一番
2021年,汽车锂离子电池需求为340GWh,是2020年的两倍多。这一增长是由电动乘用车的增长(注册量增加120%)所推动的。2021年,电池电动汽车(BEV)的平均电池容量为55千瓦时(kWh),低于2020年的56kWh,而插电式混合动力电动汽车的平均容量从2020年的13kWh增至2021年的14kWh。其他运输方式的电池需求,包括中重型卡车和两轮/三轮车,增长了65%。BEV轻型车辆的平均电池容量在区域上有所变化,韩国和几个欧洲国家的电池容量增长超过10%。
