Evaluation of the stability of organic solutions and metals by using microelectrode technique

Microelectrode technique tvas used to examine the stability of organic solu tions and metals because of minimum iR effect on polarization behavior. By diluting the solution, we studied the electrochemical behavior of the solve nt and solute separately PC, PC+EC solvents and LiClO4 solute were found to be oxidized at +5.73 V, +5.77 V and +4.40 V, respectively. The cathodic de composition of PC and PC+EC solvents occurred at negative potentials of 0 V because of the freshly deposited lithium. The stability of various metals (Cu, Mo, Ni, Pd, SUS304, Al, Au, Pt and W) were examined in 1 M (M=mol/dm(3 )) LiClO4/PC Solution and categorized according to their anodic and cathodi c behaviors.
