Batteries for electric vehicles: Reuse and recycling.

Many raw materials for electrically powered vehicles are limited and difficult to obtain. In addition, they are often extracted under socially and ecologically critical conditions. Reuse and recycling of e-vehicle batteries offer the opportunity to significantly reduce the demand for primary raw materials and thus increase their resource efficiency. The study provides an overview of technical potentials, hurdles and legal requirements. Applications for used batteries as stationary energy storage systems, for electrical infrastructure or for mobile applications, from trucks to home robots are analysed. Battery recycling shows that up to 99 % of raw materials and components can be recycled.
Both options help to conserve and sustainably use resources for the expansion of electric mobility.

电动汽车所需的多种原材料储量有限且获取难度颇高。此外，此类原材料的开采往往伴随社会与生态层面的严峻问题。动力电池的复用与回收，可大幅降低原生原材料的需求，进而提升资源利用效率。本研究概述了相关技术潜力、现存障碍及法律合规要求，并分析了退役动力电池的多类应用场景：包括作为固定式储能系统、电力基础设施配套设施，或是覆盖从重型卡车到家用机器人的各类移动应用。研究表明，动力电池回收可实现高达99%的原材料与组件回收率。上述两种路径均有助于节约资源，并以可持续方式支撑电动汽车产业的扩张。
