China’s EV sales have soared since 2015. The following year, a policy began requiring carmakers to provide an 8-year or 120,000-km warranty for core components like batteries. As such, large numbers started to be retired last year. This year, the number of scrapped EVs is set reach 15-20 million, and the capacity of scrapped batteries will exceed 60 gigawatt-hours, Securities Daily reported. (Source: Dialogue Earth)
