碩士 === 中國文化大學 === 材料科學與製造研究所 === 89 === The performance of Anode Dissolution and Spectroelectrochemical of the mechanically refueled Zinc/air Battery were experimently innestigated. For the successful application of Zinc/air battery, The mechanically refueled Zinc/air battery has been developed to be use in electric vehicle transportation. A low resistance electrode without electrolyte absorption, and a approximated alkaline solution mold strength. The results received show that, the Zinc/air battery by polymer binder of PvP, The size of zinc electrode and Zinc/air battery are 95mm×130mm×5mm, 100mm×135mm×20mm, respectively. For efficiently of this Zinc/air battery specific energy denisty∼118mA/cm^2. In order, to improve efficiently of this Zinc/air battery, example: specific power-current curve, the capacity of the zinc electrode. The other study moreover observed zinc anode electrode electricchemical analysis processes, in an electric oxidized current to understand the process and control of the surface of active metals reacting from excess-passivation phenomenon into non-active passivation area. The electrochemical system, Hg/HgO reference electrode, The electrochemical measure methods is LSV(line sweep voltameter) and CCD(const current discharge), to be study the three kinds ways to manufacture zinc anode electrode, that is the to additive polymer binder between zinc powder each other、compression、using metal foam be a zinc electrode. The results showed that the assembly mechanical geometer zinc electrode could eliminate the passivation of electrochemical processes, which can increase the constant current loading discharge percentage.
