With the rapid development of new energy vehicles and the energy storage industry, a large number of power batteries have reached their retirement stage. How to dispose of used batteries safely, efficiently and with high added value has become a common concern for both industry and society. Echelon utilization is currently the most practical and feasible solution, which maximizes the value of retired batteries through mature technology without exaggeration.
Many people mistakenly believe that "retired" batteries are completely scrapped. In fact, when the capacity of a power battery drops below 80%, it is no longer suitable for electric vehicles, but still retains 50%–80% of its effective capacity. Echelon utilization refers to professionally testing, sorting, grouping, reassembling and safely managing these batteries, then reusing them in scenarios with lower power and range requirements, such as communication base station backup power, residential and industrial energy storage, solar street lamps, low-speed electric vehicles and emergency power supplies.
Compared with direct recycling, echelon utilization better follows the logic of circular economy: making full use of the residual value of batteries before resource recovery, which improves economic benefits and reduces environmental impact. The formal echelon utilization process is strict and controllable, covering battery collection, non-destructive testing, consistent sorting and integrated application, and its safety and stability have been widely verified in communication and energy storage fields.
In terms of social benefits, echelon utilization reduces the pollution risk caused by random disposal of used batteries and lowers the dependence on new mineral resources, helping achieve carbon peaking and carbon neutrality goals. For enterprises, it cuts the cost of energy storage and backup power; for society, it builds a more sustainable industrial chain for batteries.
Without conceptual hype or excessive promotion, echelon utilization of used batteries is a tangible, applicable green technology. It realizes the full life-cycle value of each battery and promotes the low-carbon and circular development of the new energy industry in a down-to-earth way.
