摘要： A method for preparing an electrochromic device. In the method the device is prepared by inserting monovalent cations into a reducing electrochromic layer in advance, for instance, through a dry process. In particular, the method involves inserting monovalent cations into an electrochromic layer which includes a reducing electrochromic material. Then, subsequently and sequentially, placing an electrolyte layer and an ion storage layer on the electrochromic layer. In this way, it is possible to improve driving durability of the electrochromic device.

摘要： A negative electrode having a carbon-based thin film formed on at least one surface of a lithium metal layer, and a lithium secondary battery including the same. A carbon-based thin film formed on at least one surface of a lithium metal layer blocks side reactions caused by direct contact between the lithium metal layer and an electrolyte as well as increasing a specific surface area of a negative electrode, and thereby suppresses lithium dendrite formation, and by obtaining current density distribution uniformly, enhances cycle performance, reduces an overvoltage to improve electrochemical performance of a lithium secondary battery.
