By the end of 2020, the number of new energy vehicles in China reached 4.92 million. In the same year, the sales volume of new energy passenger vehicles in Europe exceeded 1.367 million, surpassing China to become the champion of global new energy sales in 2020.With the continuous improvement of the ownership of new energy vehicles, power batteries enter the stage of large-scale decommissioning. The accumulative decommissioning amount of power batteries in China will reach 90.5GWh in 2022.The value chain of the whole life cycle of the power battery can be further improved through the cascade utilization, so as to give full play to the performance of the power battery and excavate the incremental value of the battery.

With the improvement of power battery quality and the increase of cycle times, the proportion of echelon utilization in decommissioned batteries increases gradually. At the same time, with the continuous progress of ladder utilization technology, ladder utilization is developing towards a more safe and reliable direction.

Organized by Jiangsu Huayou Energy Technology Co., Ltd, Supported by China EV 100, and co-organized by GDMMC, the 2021 First Huayou Lithium-ion Battery Estates Utilization International Summit will be held in Nanjing Zijing International Hotel from June 2nd to 3rd.The event form is both online and offline, around the theme "innovation value, build green resources", focus on lithium ion battery results of policy research, technology research and development, pilot and case sharing, invite domestic and foreign related research institutions and industry experts and representatives of enterprises and lithium ion battery arrangement in use of the hot issues for further discussion.
