Are Cascade utilization technologies of spent power batteries sustainable?

And it is an industry consensus to promote the sustainable development of the cascade utilization industry of spent power batteries. In this work, the cascade utilization technologies of spent power battery in the field of energy storage are systematically described.

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.

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.

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.

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.

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.
