The mechanism of the electrochemical intercalation of LiNiO2 (LNO) electrodes in an aqueous LiNO3 electrolyte was investigated with special focus on the electrode/electrolyte interfacial reaction including the hydration state of Li+ ions. Electrochemical measurements, the Nernst equation, and in situ X-ray diffraction analysis revealed that lithium ion was main intercalation species, instead of proton, into LNO in aqueous electrolytes. In addition, calculation of the lattice parameters of LNO during charge/discharge processes indicated the co-intercalation of Li+ ions with H2O molecules, supported by the activation energy of Li+ ions estimated for the intercalation. Furthermore, in situ Raman spectra showed that partially hydrated Li+ ions were co-intercalated into LNO.
