Electroplating systems and methods with increased metal ion concentrations

An electroplating method comprising:

• providing a first portion of an electrolyte feedstock to a first compartment of an electrochemical cell;
• providing a second portion of the electrolyte feedstock to a second compartment of the electrochemical cell, wherein the second compartment and first compartment are separated by a first membrane;
• providing an acidic solution to a third compartment of the electrochemical cell, wherein the third compartment and second compartment are separated by a second membrane;
• heating the electrochemical cell to a temperature of greater than or about 40° C.;
• applying a current to the electrochemical cell, wherein an anode of the electrochemical cell is disposed proximate the first compartment and across from the first membrane, and a cathode of the electrochemical cell is disposed proximate the third compartment and across from the second membrane;
• forming an anolyte from the first portion of the electrolyte feedstock and a catholyte from the second portion of the electrolyte feedstock, wherein the anolyte and catholyte are formed simultaneously in the electrochemical cell;
• and
• providing at least a portion of the anolyte to an anode chamber of an electroplating chamber for electroplating.

An electroplating method comprising:

• providing a first portion of an electrolyte feedstock to a first compartment of an electrochemical cell, wherein the first compartment comprises a volume of greater than or about 200 L;
• providing a second portion of the electrolyte feedstock to a second compartment of the electrochemical cell, wherein the second compartment and first compartment are separated by a first membrane, and wherein the second compartment comprises a volume of greater than or about 250 L;
• providing an acidic solution to a third compartment of the electrochemical cell, wherein the third compartment and second compartment are separated by a second membrane, and wherein the third compartment comprises a volume of less than or about 50 L;
• heating the electrochemical cell;
• applying a current to the electrochemical cell, wherein an anode of the electrochemical cell is disposed proximate the first compartment and across from the first membrane, and a cathode of the electrochemical cell is disposed proximate the third compartment and across from the second membrane;
• forming an anolyte and a catholyte;
• and
• providing at least a portion of the anolyte to an anode chamber of an electroplating chamber for electroplating.
