マイクロ電極を用いる有機電解液と金属の安定性の評価

抄録

Microelectrode technique was used to examine the stability of organic solutions and metals because of minimum iR effect on polarization behavior. By diluting the solution, we studied the electrochemical behavior of the solvent and solute separately ; PC, PC+EC solvents and LiClO₄ solute were found to be oxidized at +5.73V, +5.77V and +4.40V, respectively. The cathodic decomposition of PC and PC+EC solvents occurred at negative potentials of 0V because of the freshly deposited lithium. The stability of various metals (Cu, Mo, Ni, Pd, SUS304, Al, Au, Pt and W) were examined in l M (M=mo1/dm³) LiClO₄/PC solution and categorized according to their anodic and cathodic behaviors.
