Abstract

Embodiments of the present technology include electroplating methods that include providing a first portion of an electrolyte feedstock to a first compartment of an electrochemical cell. The first portion of an electrolyte feedstock may be characterized by an initial metal ion concentration and an initial acid concentration. The methods may include providing a second portion of an electrolyte feedstock to a second compartment of the electrochemical cell. The second compartment and first compartment may be separated by a first membrane. The methods may include providing an acidic solution to a third compartment of the electrochemical cell. The third compartment and second compartment may be separated by a second membrane. The acidic solution may be characterized by an initial acid concentration. The methods may include applying a current to an anode of the electrochemical cell. The anode of the electrochemical cell may be disposed proximate the first compartment and across from the first membrane.
