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.
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.
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.
