We predicted the degradation and long-term cycle life of lithium-ion batteries using an electrochemical-based lithium plating/ stripping model. We did not consider the complex degradation mechanism of lithium-ion batteries; we only applied the lithium plating/stripping model to perform numerical analysis and calculated the capacity fade during cycling, loss of lithium inventory, and charge/discharge performance. The results showed that a higher capacity fade was observed at lower temperatures, higher C-rates, and higher lithium plating kinetic rates. In addition, the more aged cell tended to be the greater the initial voltage increase during charging, and the shorter the charging time in CC mode.
