How long does a battery last in a cascade?

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.

Does cascade use reduce battery waste?

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.

How does China treat lithium ion batteries?

At present, China mainly treats LIBs through cascade utilization based on their capacity retention rate: Retired LIBs with a capacity retention rate of about 70 % are generally converted into energy storage batteries for cascade utilization, while spent lithium-ion batteries (SLIBs) with a capacity retention rate of <30 % are directly recycled.

Are spent lithium-ion batteries causing a blowout retirement?
