Binder for electrode of lithium secondary cell |
| abstract |
The problem to be solved by the present invention is to provide a binder capable of sustaining binding properties against volume expansion and contraction of the active material during charging and discharging in the formation of an electrode layer in which silicon alone or in combination with a negative electrode active material. . As a binder for an electrode of a lithium secondary battery containing a polyurethane aqueous dispersion, the polyurethane aqueous dispersion is a hydrophilic group-containing poly obtained by using at least (A) an organic polyisocyanate and (B) a compound having at least one active hydrogen group. The compound containing urethane, wherein the content of (A) is 50% by mass or more and 80% by mass or less with respect to the hydrophilic group-containing polyurethane, and the compound (B) has at least one active hydrogen group is (B1) 2 or more active It relates to a binder for an electrode of a lithium secondary battery, comprising a compound having a hydrogen group and (B2) a compound having at least one active hydrogen group and at least one ionic hydrophilic group. |
