Abstract: In this work, lithium plating is investigated by means of voltage relaxation and in situ neutron diffractionin commercial lithium-ion batteries. We can directly correlate the voltage curve after the lithium platingwith the ongoing phase transformation from LiC12 to LiC6 according to the neutron diffraction dataduring the relaxation. Above a threshold current of C/2 at a temperature of -2 °C, lithium plating increasesdramatically. The results indicate that the intercalation rate of deposited lithium seems to beconstant, independent of the deposited amount. It can be observed that the amount of plating correlateswith the charging rate, whereas a charging current of C/2 leads to a deposited amount of lithium of 5.5%of the charge capacity and a current of 1C to 9.0%.
