This study analyzes the economic benefits of cascade utilization of retired power batteries, focusing on two key applications: grid energy storage and China Tower base stations. Currently, these account for 31 % and 52 % of second-life battery use, respectively, with a smaller portion used in low-speed EVs (Hu et al., 2021).
This study explores technological and policy-driven innovations to mitigate the cost barrier of cascade batteries in energy storage, leveraging national support and optimized recycling. It presents strategies to enhance economic and operational viability for the secondary use of retired batteries.
Therefore, research on scrapped power batteries should enable the regrouping battery packs to be directly applied to cascade utilization scenarios, and effective methods should be proposed to efficiently cluster and regroup large-scale spent power batteries in the future .
The cascade energy storage system serves the load with power when fully charged and draws electricity from the main power grid when its charge is inadequate. Furthermore, should the energy storage battery remain uncharged, the primary power grid concurrently powers both the load and the cascade energy storage system.
