Abstract: Systems and methods of providing an electrolyte membrane for metal batteries are described. According to aspects of the disclosure, a method includes preparing a mixture including an electrolyte portion and a matrix precursor portion, forming an electrolyte membrane by initiating polymerization of the gel-forming precursor and the gel-forming initiator to thereby form a polymer matrix, and disposing the electrolyte membrane between an anode and a cathode. The matrix precursor portion includes a gel-forming precursor and a gel-forming initiator. The electrolyte portion is disposed substantially throughout the polymer matrix.

Abstract: Systems and methods of providing self-healing gel-type electrolyte composites for metal batteries are disclosed. According to aspects of the disclosure, a method includes preparing a ternary mixture including an electrolyte portion, a matrix precursor portion, and a self-healing portion, forming a self-healing gel-electrolyte membrane by initiating polymerization of the gel-forming precursor and the gel-forming initiator to thereby form a polymer matrix, and disposing the self-healing gel-electrolyte membrane between an anode and a cathode. The self-healing portion includes a self-healing precursor that is flowable and a self-healing initiator. The matrix precursor portion includes a gel-forming precursor and a gel-forming initiator. The electrolyte portion and the self-healing portion are disposed substantially throughout the polymer matrix and the polymer matrix includes a plurality of gel-forming active sites.

Abstract: Systems and methods of providing an electrolyte membrane for metal batteries are described. According to aspects of the disclosure, a battery cell includes an anode, a cathode, and an electrolyte membrane therebetween. The electrolyte membrane is formed from a mixture including a matrix precursor portion and an electrolyte portion. In some aspects, the membrane is polymerized after being applied to the battery component.
