Systems and methods for processing and managing used lithium-ion batteries

A method for processing used lithium-ion batteries, the method comprising:

• disassembling a used lithium-ion battery;
• analyzing cells of the used lithium-ion battery during a discharge test;
• assigning grades to a plurality of factors for each of the analyzed cells based on the discharge test;
• determining a state-of-health for each of the analyzed cells based on the grades of each of the plurality of factors;
• categorizing each of the analyzed cells into one of a plurality of categories comprising a reuse category, a repurpose category, and a recycle category based on the state-of-health of each of the analyzed 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.

A method for processing used lithium-ion batteries, the method comprising:

• individually assessing a state-of-health of cells of a used lithium-ion battery configured for a high-load application;
• categorizing each of the cells into one of a plurality of categories comprising a reuse category, a repurpose category, and a recycle category based on the state-of-health of each of the cells;
• and
• repurposing the cells categorized in the repurpose category into a battery configured for a low-load application.
