The capacity loss in a lithium-ion battery originates from (i) a loss of active electrode material and (ii) a loss of active lithium. The focus of this work is the capacity loss caused by lithium loss, which is irreversibly bound to the solid electrolyte interface (SEI) on the graphite surface.
An open circuit voltage model is applied to quantify the loss mechanisms (i) and (ii). The results show that the lithium loss is the dominant cause of capacity fade under the applied conditions. They experimentally prove the important influence of the graphite stages on the lifetime of a battery.
Neither the loss of active anode material, AML A, nor of active cathode material, AML C, influenced the full cell capacity loss at this stage of degradation. The fit results determined that active lithium loss was slightly higher than the full cell capacity loss, which is physically not possible.
When active lithium is lost, the cathode is not fully lithiated, when the anode is delithiated and the anode OCP shifts to the left compared to the cathode OCP. Then, the anode is delithiated when Q A,2 is discharged from the fully charged cell. The loss of active lithium can hence be calculated from the difference: Figure 4.

The results show that the capacity and power degradation is more severe under the condition of low discharge rate, not the widely accepted high discharge rate.
The experimental tests presented in Fig. 3 show that the capacity loss of lithium-ion batteries caused by high-dynamic mechanical impacts is significantly increased under low-temperature conditions. This may be because graphite anodes have more poor mechanical characteristics at low temperatures.
