It introduces secondary utilization modes of retired power battery, summarizes status and trend of scrapping and secondary utilization of power batteries in different cathode materials, points out the challenges and opportunities, analyzes the hidden dangers of power lithium ion batteries in production and vehicle-usage as well as the safety requirements and risks of the secondary utilization of the retired-power batteries in four different application scenarios. A safety strategy to optimize secondary utilization matching with different safety foundation of different type of power battery and vehicle application is proposed. Meanwhile, it is suggested to innovate power battery development and design mode, to develop key technologies for secondary utilization, to accelerate business model innovation and to foster a bigger and more successful industry as a comprehensive strategy to improve the safety of battery secondary utilization.
