The ever-growing field of energy storage needs the development of fast cycling rate and high energy density batteries and substantial research efforts are required to characterize them for improved performances. Operando X-ray diffraction is the most effective and convenient laboratory technique to get a deep insight into structural and electrochemical changes during operating conditions of batteries. In this work, we presented our newly developed operando LeRiChe’S Cell v2 which has been used to study NMC electrode materials not only with liquid electrolyte but also in solid-state batteries. The high brilliance of our laboratory diffractometer combined with our newly developed operando LeRiChe’S Cell v2 allowed us to investigate electrode materials at high C rates in a very short span of time.
