description | A method for processing used lithium-ion batteries includes disassembling a used lithium-ion battery configured for a high-load application, inspecting cells of the used lithium-ion battery, charging the cells, and assessing a state-of-health of each of the cells by running a discharge test to determine an internal resistance and a capacity, comparing the internal resistance and the capacity with manufacturer specifications, and determining the state-of-health based on the comparison. The method also includes categorizing each of the cells into a reuse category, a repurpose category, or a recycle category based on the state-of-health of the cells and reusing the cells categorized in the reuse category in a battery configured for a high-load application, repurposing the cells categorized in the repurpose category into a battery configured for a low-load application, and recycling the cells categorized in the recycle category. |
