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.

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.

What is the difference between a battery and a cascade?

Compared with new batteries, spent power batteries can reduce the cost of energy storage projects, and thus reduce the cost of energy storage for users. On the other hand, the cascade utilization realizes the full utilization of resources and has greater environmental benefits.

How does a cascade energy storage system work?

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.

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.
