Soft X-ray nanoscopy employing the scanning transmission X-ray microscope (STXM) in the Pohang Light Source (PLS-II), which can provide chemical structural information of various functional materials at tens of nanometer scale, has become a powerful study in analytical microscopic research. The nanoscopy beamline is operating currently at the optimum condition in its focused beam size ~30 nm and photon energy resolution < 0.1 eV in the soft X-ray energy range (200-1650 eV). This article presents a short review of the STXM and its applications of functional materials including Li-ion batteries. A brief discussion on the opportunities in the STXM applications is presented at the end.
