  • Publication number: 20220190342
    Abstract: A binder for an all-solid-state secondary battery that can control a decrease in ionic conductivity, is excellent in binding properties and oxidation resistance, and can realize favorable cycle life characteristics even under a high voltage; and a binder composition for an all-solid-state secondary battery containing the binder. A binder for an all-solid-state secondary battery includes a polymer (A) which includes a repeating unit (a1) derived from an unsaturated carboxylic acid ester (excluding an unsaturated carboxylic acid ester having a hydroxyl group) and a repeating unit (a2) derived from a compound having a tertiary amino group, a weight-average molecular weight (Mw) of the polymer (A) being from 250000 to 3000000, and an endothermic peak being observed at ?10° C. or lower when differential scanning calorimetry (DSC) is performed on the polymer (A) in accordance with JIS K 7121.

  • Publication number: 20130323588
    Abstract: An electrode binder composition includes polymer particles. The polymer particles include 5 to 40 parts by mass of a constituent unit (A) derived from an alpha,beta-unsaturated nitrile compound, and 0.3 to 10 parts by mass of a constituent unit (B) derived from an unsaturated carboxylic acid, and have a number average particle size of 50 to 400 nm. The electrode binder composition has a gel content of 90 to 99% and an electrolyte solution swelling ratio of 110 to 400%.
