Abstract:
1. A binder composition for batteries, comprising: (A) a polymer that comprises at least one structural unit selected from structural units represented by formulae (a1) to (a5), and (f) a functional group comprising a nitrogen atom, an oxygen atom, a silicon atom, a germanium atom, a tin atom or a combination thereof; and (B) a liquid medium, the polymer (A) having a solubility of no less than 5 g in 100 g of cyclohexane at 25° C. and 1 atm, wherein, in the formulae (a1) to (a5), R wherein the polymer (A) comprises at least one structural unit selected from the structural units represented by the formulae (a1) and (a2), and a total content of the structural units represented by the formulae (a1) and (a2) is no less than 60% by mol with respect to a total content of the structural units represented by the formulae (a1) to (a5).
