摘要： Provided is an electrode for electrolysis and a preparation method of the same. The electrode for electrolysis has an improved needle-like structure of a rare earth metal compared to conventional electrodes, and thus detachment of catalytic materials is reduced, so that the electrode is excellent in durability such as exhibiting stable performance even in a reverse current flow. Further, since the electrode for electrolysis has a low overvoltage value, an overvoltage required amount of the electrolytic cell can be remarkably reduced. In addition, an electrode for electrolysis having the above effect can be prepared without introducing additional precursors or changing manufacturing facilities.

摘要： A positive electrode active material for a lithium-sulfur battery, and more particularly, to a positive electrode active material for a lithium-sulfur battery including metal sulfide nanoparticles and a preparation method thereof. The metal sulfide nanoparticles with large specific surface area applied to the positive electrode active material for the lithium-sulfur battery according to the present invention acts as a redox mediator during charging and discharging of the lithium-sulfur battery, thereby reducing the shuttle response by not only inhibiting the formation itself of polysulfides with elution properties, but also, even if polysulfides are eluted, adsorbing them and thus preventing them from diffusing into the electrolyte solution, and thus the capacity and life characteristics of the lithium-sulfur battery can be improved.
