Advanced energy technology arises from the understanding in fundamental science, thus rest in large on in-situ/operando characterization tools for observing the physical and chemical interfacial processes. The energy materials and devices have been largely limited in a framework of thermodynamic and kinetic concepts or atomic and nanoscale. Synchrotron radiation based X-ray spectroscopic techniques offers unique characterization in many important energy materials of energy conversion, energy storage and catalysis in regards to the functionality, complexity of material architecture, chemistry and interactions among constituents within. We have developed the in-situ/operando soft X-ray spectroscopy for the studies of catalytic and electrochemical reactions in recent years, and overcome the challenge that soft X-rays cannot easily peek into the liquid electrochemical cells under vacuum condition. The unique design of in-situ/operando soft X-ray spectroscopy instrumentation design and fabrication principle and a number of examples will be presented. A state-of-the-art beamline with multimodal characterization capabilities of in-situ STXM, APXPS and RIXS is now constructed at the ALS.<br/>
