  Electrolyzer ea ion-membrane e na le anode, cathode, le lera la cation-exchange kapa anion-exchange membrane. Nakong ea electrolysis:
• Membrane ea cation-Exchange:E lumella cations (mohlala, Na⁺, Ca²⁺) ho feta ha e ntse e thibela li-anion (Cl⁻, SO₄²⁻), e lebisa phallo ea ion ho li-electrode tse fapaneng.
• Lits'ebetso tsa Electrochemical:
• Anode:Oxidation ea li-ion tsa chloride e hlahisa khase ea chlorine le hypochlorite, e senyang lintho tse phelang le ho bolaea metsi.
  2Cl−→Cl2+2e−2Cl⁻ → Cl₂ + 2e⁻2Cl−→Cl2+2e−
• Cathode:Phokotso ea metsi e hlahisa khase ea haedrojene le li-ion tsa hydroxide, e ntlafatsa pH le ho khothaletsa pula ea li-ion tsa tšepe.
  2H2O+2e−→H2+2OH−2H₂O + 2e⁻ → H₂ + 2OH⁻2H2O+2e−→H2+2OH−
