BINDER FOR ELECTRODE OF LITHIUM SECONDARY CELL |
| 摘要 |
A binder for an electrode of a lithium secondary battery contains a polyurethane aqueous dispersion. The polyurethane aqueous dispersion contains a hydrophilic group-containing polyurethane obtained by using at least (A) an organic polyisocyanate and (B) a compound having one or more active hydrogen groups. (A) the organic polyisocyanate has a content of 50 mass % or more and 80 mass % or less based on the hydrophilic group-containing polyurethane. (B) the compound having one or more active hydrogen groups contains (B1) a compound having one or more active hydrogen groups and (B2) a compound having one or more active hydrogen groups and one or more ionic hydrophilic groups. |
