Abstract: The present invention generally relates to materials for electrochemical cells, e.g., for use in batteries such as lithium-ion batteries, and other applications. For example, certain embodiments of the present invention provide a composition for a slurry or a slurry for the manufacture of an electrode for an electrochemical cell. The slurry, in certain embodiments, comprises a combination of ionomer, binder, conducting additive, electroactive materials, and water. The ionomer, in some embodiments, includes a polymer backbone, one or more anionic substituents (which may be in the backbone and/or in one or more pendant groups), and one or more cations.

Abstract: The present invention generally relates to poly(lithium acrylate) (PLA) and other materials, which may be used in polymer blend membranes and other applications. Certain embodiments, for example, relate to methods of preparing poly(lithium acrylate), or membranes comprising poly(lithium acrylate). In some embodiments, lithium acrylate monomer may be obtained through neutralization reaction between a strong inorganic base and a weak organic acid. Such materials can be used in electrochemical cells, for example, as a membrane, e.g., for use in batteries such as lithium-ion batteries, or other applications. In certain cases, the molecular weight of the PLA may be between 102 Da to 106 Da. In some embodiments, the membrane may have a mechanical strength of elastic stress modulus between 5 kPa to 500 MPa with strain from 0% to 200%. In some embodiments, the membrane may have an ionic conductivity between 10−9 S cm−1 to 10−3 S cm−1.
