This paper discusses the technologies for S-LIBs cascade utilization, including new techniques for battery condition assessment and the combination of informatization for different battery identification and dismantling. After complete scrapping, the most crucial aspect is the recycling of cathode materials.
Even after cascade utilization, final treatment of the batteries is necessary, involving disassembly and recovery of various components including cathode materials, anode materials, steel casings, current collectors, and other components. For cathode materials that contain valuable metals, the purpose of treatment is to reuse these metals.
Cascade utilization involves downgrading batteries from high-standard applications to lower-standard application scenarios in the form of battery packs, battery modules, and individual cells (Hua et al., 2021). The first step is to inspect the spent battery packs to ensure that their appearance and performance are intact (Wang et al., 2024a).
A lifespan of 5 years was proposed for the cascade use stage of these retired batteries, taking the decay ratios of LFP and NCM batteries as a reference. During the cascade use stage, the capacity for energy storage decreases as battery capacity continues to decay.
Cascade use mitigates the explosive increase in battery waste Sources of battery waste include batteries in RTBs that cannot be repurposed for cascade use and batteries eliminated from cascade use. Due to the diversity of approaches for cascade use, RTBs in particular may fail to be collected by certificated collection companies.
In this study, the demand for cascade use of RTBs was defined as the capacity required for ancillary energy storage facilities in solar photovoltaic and wind-power plants. These facilities are used to buffer and mitigate power demand spikes to the grid associated with the instability of solar and wind power.
