We report a novel dual‐IR window/electrode operando infrared (IR) spectroscopy method for battery research. In addition to keeping all the features of the in‐situ/operando IR spectroscopic methodologies for batteries reported in the literature so far, the dual‐IR window/electrode configuration reported herein offers a unique advantage of accessing both, anode and cathode processes quasi‐simultaneously by rotating the dual‐window/electrode IR battery cell 180° step‐wise in the same operando real‐battery‐like cell. The proof‐of‐concept studies demonstrated clearly its investigative advantages in gaining broader insights into the chemistry of batteries during charging/discharging and beyond.
