Why do we use retired power batteries in energy storage systems?

The cascade utilization of retired power batteries in the energy storage system is a key part of realizing the national strategy of “carbon peaking and carbon neutrality” and building a new power system with new energy as the main body [ 1 ].

Are retired power batteries safe for large-scale energy storage systems?

However, compared with the traditional energy storage system that uses brand-new batteries as energy storage elements, the performance of retired power batteries has been attenuated by the use of new energy vehicles, so the safety issues when applied to large-scale energy storage systems are more prominent [ 2 ].

Can retired batteries be used as Second-Life battery energy storage systems?

However, their use as stationary battery energy storage systems (BESSs) is more common. Repurposing retired batteries for application as second-life-battery energy storage systems (SLBESSs) in the electric grid has several benefits: It creates a circular economy for EV batteries and helps integrate renewable energy sources into the electrical grid.

Can retired lithium batteries be used for energy storage?

The cascade utilization of retired lithium batteries to build an energy storage system is an effective means to achieve my country's dual-carbon goal, but safety issues restrict large-scale promotion and application.

What can a retired battery do?

Besides ESSs, retired batteries possess a diverse range of potential applications 18, spanning various fields, such as communication base stations (CBSs) 14, 17 and low-speed vehicles (LSVs) 19, 20.

Can retired batteries be reused?

Repurposing the battery packs for second-life applications is a viable and sustainable option. Various terms that can be used for the secondary use of retired batteries are “second-life”, “second-use”, and “reuse” . We will use the term “second-life” throughout this paper for the reuse of the retired batteries.
