US 2026/0179956 A1 · POLYMERIC BINDERS FOR ELECTROCHEMICAL CELLS

Abstract

Embodiments described herein relate to binders including one or more portions, and electrochemical cells including the same. Specifically, in some embodiments, binders may include a first portion, a second portion, and, optionally, a functional portion coupled to at least one of the first portion or the second portion. In some embodiments, the functional portion may also be coupled to first portion. In some embodiments, the second portion is coupled to the first portion in a linear structure, or grafted as a side chain at a predetermined location along a length of the first portion. In some embodiments, the first portion has a first glass transition temperature, and the second portion has a second glass transition temperature. The second glass transition temperature may be greater than the first glass transition temperature.
