Melting of the anode commonly occurs

Web7 apr. 2024 · The endothermic peak of PVDF-HFP SE appears at 169 °C, which represents the melting temperature ( Tm) of PVDF-HFP. When adding La 2 O 3, the peaks decrease significantly to 157 °C, which reveals the reduced crystallization stability of PVDF-HFP. [ 47] WebThe electrode where oxidation occurs is called the anode. In the half-cell that contains the Cu electrode in aqueous CuSO 4 solution, the half-reaction is Cu2+(aq) + 2e−⎯→ Cu(s). In this half- reaction,the Cu2+ions in solution gain electrons to become Cu solid;that is,reduction is taking place.
