CELL MANUFACTURING USING LIQUID-BASED THERMAL SYSTEM |
摘要 |
A method of manufacturing cells includes: assembling cells that include at least electrodes and electrolyte contained in a housing; after assembly, storing the cells in contact with a liquid-based thermal system; circulating liquid in the liquid-based thermal system at least while the cells are in contact with the liquid-based thermal system, the liquid having a first temperature; after storing the cells at the first temperature, and while the cells have at least a partial charge, performing a first open circuit voltage (OCV) test on the cells; after the first OCV test, storing the cells at a second temperature lower than the first temperature; after storing the cells at the second temperature, performing a second OCV test on the cells; and for each of the cells, discarding or keeping the cell based at least in part on the first and second OCV tests. |
