Abstract: With the rapid spread of new energy vehicles，the number of power lithium batteries in China is increasing day by day，the price of battery raw materials is rising and the pressure on the environment of a large number of discarded batteries is increasing， and the recycling of decommissioned power lithium batteries has also been put on the agenda. At present，power battery recycling includes two methods：echelon utilization and material recovery. This paper focused on the echelon utilization，and stated the necessity of the echelon utilization；the author analyzed all aspects including national policy，economic orientation，technology，and professional talents. The problems encountered at present were analyzed and corresponding suggestions were put forward.

Key words: power lithium battery, recycling, echelon utilization
