  • Lead Acid Battery Slurry Comprising Polyelectrolyte Comb Copolymers
    Publication number: 20100075231
    Abstract: The invention provides a slurry, such as a lead-acid battery slurry, comprising a polyelectrolyte comb copolymer and lead oxide. Use of polyelectrolyte comb copolymers results in a slurry with low viscosity. In addition, the use of polyelectrolyte comb copolymers controls the growth (e.g., size, morphology and location) of the inactive species, and thus, improves battery cycle life.

  • Gelcasting methods
    Patent number: 6066279
    Abstract: A method of gelcasting includes the steps of providing a solution of at least hydroxymethylacrylamide (HMAM) and water. At least one inorganic powder is added to the mixture. At least one initiator system is provided to polymerize the HMAM. The initiator polymerizes the HMAM and water, to form a firm hydrogel that contains the inorganic powder. One or more comonomers can be polymerized with the HMAM monomer, to alter the final properties of the gelcast material. Additionally, one or more additives can be included in the polymerization mixture, to alter the properties of the gelcast material.
