Therefore, the Heyrovsky step or Tafel step should be interrupted to avoid HER. Bearing these in mind, we introduced 0.5 g L −1 4-hydroxybenzaldehyde (HB) additives into 2 M ZnSO 4 electrolytes (HB/ZnSO 4) to improve the cycle stability of Zn metal anodes. Experimental and theoretical calculation results demonstrated that the aldehyde …

The Tafel Equation. The Tafel Equation is expressed as follows: where. η is the overpotential in V, A is the Tafel slope in V, i is the current density in A/m 2, and i 0 is the exchange current density in A/m 2 . The +/- sign depicted in the equation relates to whether the analysis refers to an anodic (+) or cathodic (-) process.
