Patent number: 11145897Abstract: 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.Type: GrantFiled: February 1, 2019Date of Patent: October 12, 2021Assignee: GM Global Technology Operations LLCInventors: Fang Dai, Mahmoud Abd Elhamid, Mei Cai, Anne M. Dailly, Robert M. Lapierre

Patent number: 10476105Abstract: 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.Type: GrantFiled: August 18, 2017Date of Patent: November 12, 2019Assignee: GM Global Technology Operations LLCInventors: Fang Dai, Mahmoud Abd Elhamid, Mei Cai, Anne M.

Patent number: 4806294Abstract: A method of making a foam injection molded article is disclosed wherein corrosion of the mold element is significantly reduced or substantially eliminated. The method comprises dispersing effective amounts of a primary chemical blowing agent of sodium borohydride and an activation system of sodium bicarbonate/citric acid mix into a polymer resin to form a mixture. The mixture is then heated whereby the activation system releases water and the sodium borohydride reacts with the water to produce hydrogen gas. The mixture is subsequently injected into a mold to obtain expansion of the polymer resin to form the foam article. The invention also comprehends a corresponding chemical blowing agent composition.Type: GrantFiled: June 15, 1988Date of Patent: February 21, 1989Assignee: Enron Chemical CompanyInventors: Robert M. Lapierre, Nicholas J. Leonardi
