Abstract:
The present invention relates to an integrated electrode-bipolar plate and a method for manufacturing the same. An electrode and a bipolar plate are joined and integrated by a thermostatic adhesive sheet. The thermostatic adhesive sheet contains a certain kind of thermostatic resin and conductive filler, thus enhancing energy efficiency due to contact resistance at interfaces. Moreover, the adhesive sheet is also capable of performing the role as a protective coating surface, such as against acidity, in order to provide an integrated electrode-bipolar plate which can provide excellent durability stability, work stability and continuity of the processes.
Abstract:
The present invention relates to a cathode catalyst for a lithium-air battery, a manufacturing method thereof, and a lithium-air battery comprising the same and, in particular, to a cathode catalyst capable of improving the storing capacity of a battery for charging and discharging electricity and increasing the cycle lifetime of charging and discharging electricity, a method thereof and a lithium-air battery comprising the same. The cathode catalyst has a layered perovskite structure and includes lanthanum and nickel oxide. A cathode for a lithium-air battery is produced by using the cathode catalyst including the layered perovskite and the lithium-air battery is provided by using the cathode. The storing capacity of a lithium-air battery for charging and discharging electricity can be increased and the cycle lifetime of charging and discharging electricity can be improved.

PURPOSE: A redox couple-supported nanoparticle is provided to have a lot of redox couples in the pores or surface of a nanoparticle, thereby increasing the density of a redox couples and suppressing crossover of the redox couples. CONSTITUTION: A redox couple-supported nanoparticle(200) is manufactured by dipping a micropore-containing nanoparticle(210) in a solution containing a redox couple(220) for redox flow batteries and drying the result. A redox flow battery comprises a positive electrode cell(120) which includes a positive electrode(121) and a positive electrolyte(122); a negative electrode cell(110) which includes a negative electrode(111) and a negative electrolyte; and an ion exchange film(130) which is located between the positive electrode cell and negative electrode cell. The positive electrolyte and/or negative electrolyte include the redox couple-containing nanoparticles. [Reference numerals] (AA) Electron movement;
