Sumario:In operando resonance Raman spectroscopy suggests quantitative correlation between phonon band properties and the amount of charge storage of high‐energy density NiO(2)H(x) battery/pseudocapacitive material. Comparing the spectroscopic evolution using different electrolytes reveals the contributions of breaking/formation of O–H bonds and insertion/extraction of cations to electrochemical charge storage of NiO(2)H(x).
