Herein, we report the soft X-ray absorption spectroscopic investigation for Li(Ni_0.8Co_0.1Mn_0.1)O₂ cathode material during charging and discharging. These measurements were carried out at the Mn <i>L</i>-, Co <i>L</i>-, and Ni <i>L</i>-edges during various stages of charging and discharging. Both the Mn and Co <i>L</i>-edge spectroscopic measurements reflect the invariance in the oxidation states of Mn and Co ions. The Ni <i>L</i>-edge measurements show the modification of the oxidation state of Ni ions during the charging and discharging process. These studies show that <i>e_g</i> states are affected dominantly in the case of Ni ions during the charging and discharging process. The O <i>K</i>-edge measurements reflect modulation of metal–oxygen hybridization as envisaged from the area-ratio variation of spectral features corresponding to <i>t_2g</i> and <i>e_g</i> states.
