Jeong Kuk Shon,Hyo Sug Lee,Gwi Ok Park,Jeongbae Yoon,Eunjun Park,Gyeong Su Park,Soo Sung Kong,Mingshi Jin,Jae-Man Choi,Hyuk Chang,Seok-Gwang Doo,Ji Man Kim,Won-Sub Yoon,Chanho Pak,Hansu Kim,Galen D. Stucky +15 more
TL;DR: Insight into the electrochemical results, obtained by in situ X-ray absorption, scanning transmission electron microscopy analysis combined with electron energy loss spectroscopy and computational modelling indicates that the nanoscale pore engineering of this transition metal oxide enables an unexpected electrochemical mass storage mechanism, and may provide a strategy for the design of cation storage materials for battery systems.
Patent
Electrode for photoelectric conversion device containing metal element and dye-sensitized solar cell using the same
TL;DR: An electrode for a photoelectric conversion device includes a transparent substrate and a transparent conductive film, in which the transparent substrate contains an added metal element on at least one surface thereof.
Patent
Electrode for secondary battery, manufacturing method thereof and secondary battery employing the same
TL;DR: In this article, an electrode for a secondary battery employing an active material layer having improved thickness uniformity by printing low-viscosity ink on the active material, and a manufacturing method of the electrode, was presented.
