However, there are still many issues facing second-life batteries (SLBs). To better understand the current research status, this article reviews the research progress of second-life lithium-ion batteries for stationary energy storage applications, including battery aging mechanisms, repurposing, modeling, battery management, and optimal sizing.
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.
Moreover, these batteries can also be employed for revenue generation for energy arbitrage (EA). While there are articles reviewing the general applications of retired batteries, this paper presents a comprehensive review of the research work on applications of the second-life batteries (SLBs) specific to the power grid and SLB degradation.

Second-life batteries (SLBs) can be used for a variety of applications. For example, the retired batteries can be used to provide charging services for an EV charging station [7, 8]. However, their use as stationary battery energy storage systems (BESSs) is more common.
Second life batteries (SLBs), also referred to as retired or repurposed batteries, are lithium-ion batteries that have reached the end of their primary use in applications such as electric vehicles and renewable energy systems (Zhu et al., 2021a).
