Customer ServiceIn 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.
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.
Simultaneously, multiple approaches to cascade use should be formally established, including the use of placing, handling and transport machinery within factories, user-side energy storage tanks, and low-speed EVs.
Under the energy storage demand scenario of 2025, the overall ratio of RTB potential to demand will continue to increase to 1.2 by 2030, at which point the capacity of RTBs will exceed China's total energy storage demand; however, 14 out of 31 provinces in mainland China will still have ratios less than 1.
