The effect of SEI growth due to cracks and anode overhang are mainly assumed to be responsible for these losses. During the rest phase at high voltages of the self-discharge these reactions also consume lithium of the anode and reduce its capacity and voltage. The effects of anode overhang originate in the mismatch in size of the electrodes and the electrode potential change due to slow lithium diffusion during the rest phase between active and overhang material. This results in an unexpectedly high discharge capacity and coulomb efficiencies greater than unity visible in Figures S4 and S5 of the following cycles of CC2 and CC3.
