Electrodes Including a Passivation Layer

An electrochemical cell, comprising:

• (i) an anode comprising an active anode species;
• (ii) a cathode comprising an active cathode species;
• and
• (iii) an electrolyte composition positioned between and in contact with the anode and the cathode;
• wherein at least the anode includes a first passivation layer comprising a first matrix material and at least a first electrolyte distributed throughout the first matrix material, the first passivation layer being positioned between the active anode species and the electrolyte composition;
• wherein the first matrix material comprises:
• (a) a cured propoxylated polymer, (b) an uncured hydrophobic glycol ether, or a combination of (a) and (b).

A method of forming an electrode, comprising:

• providing or forming an electrode-composition including an active electrode species, wherein the electrode-composition comprises a first surface;
• providing or forming a passivation-composition comprising a mixture of a matrix material and at least a first electrolyte in a liquid medium;
• coating at least a portion of the first surface with the passivation-composition to provide a liquid-containing pre-passivation layer on at least a portion of the first surface;
• and
• at least one of drying or radically curing the liquid-containing pre-passivation layer to form a pas sivation layer comprising a dry mixture of the matrix material and the first electrolyte;
• wherein the matrix material comprises:
• (a) a cured propoxylated polymer, (b) an uncured hydrophobic glycol ether, or a combination of (a) and (b).

A method of forming an electrochemical cell, comprising:

• providing or forming an anode comprising a first passivation layer defining a first anode-surface;
• providing or forming a cathode;
• and
• depositing an electrolyte composition between and in contact with the first anode-surface and the cathode;
• wherein the first passivation layer comprises:
• (i) a matrix material comprising (a) a cured propoxylated polymer, (b) an uncured hydrophobic glycol ether, or a combination of (a) and (b);
• and (ii) at least a first electrolyte.
