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.

Electrolyte membrane

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.

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.
