Keywords:infrared spectroscopy, Prussian blue analogue, secondary battery

Using in situ infrared absorption spectroscopy, redox site of Prussian blue analogues are elucidated. Analyzing the vibrational peak of CN stretching mode, redox site of NaxCo[Fe(CN)6]0.90 and NaxMn[Fe(CN)6]0.83 were assigined. Also, the spectral behavior of CN stretching mode are discussed in detail.
