aluminum electrolytic cell castable
17.7 ElectrolysisChemistry LibreTexts
Electrolytic cells are electrochemical cells with negative cell potentials (meaning a positive Gibbs free energy) and so are nonspontaneous. Electrolysis can occur in electrolytic cells by introducing a power supply which supplies the energy to force the electrons to flow in the nonspontaneous direction.
