Can a large-scale Cascade utilization of spent power batteries be sustainable?

The large-scale cascade utilization of spent power batteries in the field of energy storage is just around the corner. Although there are many obstacles in the cascade utilization of spent power batteries in the field of energy storage, the goal of achieving green and sustainable development of the power battery industry will not change.

What is Cascade utilization of spent power batteries in China?

Some application cases of cascade utilization of spent power batteries in China. The project is used to adjust the transformer power output, stabilize the node voltage level, and be able to operate off-grid. China Tower currently has more than 1.9 million base stations, and the battery required for backup power is about 44Gwh.

What is a cascade utilization battery?

Cascade utilization battery refers to the battery that has not been scrapped but its capacity has declined and cannot be continued to be used by electric vehicles, so that it can exert surplus value in the field of power storage.

Can cascade utilization extend battery service life?

Detailed cost, revenue, and policy subsidy analyses demonstrate that cascade utilization can extend battery service life by 7 years from an initial 80 % state of charge (SOC) and reduce energy storage system costs.

Why is Cascade utilization a trend in energy storage systems?

With the widespread use of new energy electric vehicles, there will be a large number of spent power batteries available in the future. Therefore, the cascade utilization in the field of energy storage systems is expected to become the trend of industry development.

Can scrapped power batteries be used in Cascade utilization scenarios?

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 .
