Outline of Final Research Achievements

To inprove the charge transfer between the electrode reaction interface by improving the adhesion between the current collector and the active material, very dense and highly crystalline Ni - Al LDH was deposited on various substrates by the liquid phase deposition method (LPD Method). As a result of examining the synthesis optimum of Ni - Al LDH, the maximum Ni - Al LDH yield was obtained at [F -] = 200 mmol L-1 and pH 8.2 regardless of the substrate material and shape. An active material layer closely adhered to the base material was constructed to achieve reduction of charge transfer resistance between the current collector and the active material by up to 80% as compared with the conventional crimp method. As a result of measuring the activation energy of charge transfer, a decrease in activation energy of about 20% was confirmed.
