Claim 0:
1. A battery cell comprising:
a cathode characterized by a matrix of first particles of cathode active material;
an anode characterized by a matrix of second particles of anode active material; and
a hydroxide-conducting polymeric material disposed along an exterior surface of the cathode, wherein the hydroxide-conducting polymeric material is characterized by a cationic backbone, wherein the hydroxide-conducting polymeric material is configured to selectively provide hydroxide ion transport across the hydroxide-conducting polymeric material while limiting cationic transport across the hydroxide-conducting polymeric material, wherein the hydroxide-conducting polymeric material is further incorporated within the cathode as a cathode binder and to encapsulate individual first particles of the matrix in the cathode, wherein the hydroxide-conducting polymeric material is further incorporated within the anode as an anode binder and to encapsulate individual second particles of the matrix in the anode,
wherein the matrix of first particles and the hydroxide-conducting polymeric material incorporated within the cathode together form a composite cathode, wherein the hydroxide-conducting polymeric material comprises less than 20% of a total volume of the composite cathode, wherein the matrix of second particles and the hydroxide-conducting polymeric material incorporated within the anode together form a composite anode, and wherein the hydroxide-conducting polymeric material comprises less than 20% of a total volume of the composite anode.
