Title:
リチウム電池用結着剤、電極作製用組成物および電極
Document Type and Number:
Japanese Patent JP6457043
Kind Code:
B2
Abstract:
The present invention relates to (1) a use of a polyacrylic acid cross-linked by a cross-linking agent selected from the compounds described in the general formulae [1] to [11], provided that the one which includes a functional group-containing vinylidene fluoride-based polymer is excluded, in a binder for a lithium cell, wherein the viscosity of the cross-linked polyacrylic acid is 0.03 to 10 kgm -1 s -1 [30 to 10000 mPa S] under 60 rpm of a rotational viscosimeter, or 10 to 400 kgm -1 s -1 [10000 to 400000 mPa S] under 0.6 rpm of a rotational viscosimeter, when measured at 20 to 25 °C, provided that the viscosity is measured in a dispersed solution of the cross-linked polyacrylic acid in water in a concentration of 1 % by weight; and to (2) a use of a polyacrylic acid cross-linked by a cross-linking agent selected from the compounds described in the general formulae [1] to [11], provided that the one which includes a functional group-containing vinylidene fluoride-based polymer is excluded, in a binder for a lithium cell, wherein an amount of the cross-linking agent is 0.001 to 0.5 % by mol, to 1 mol of acrylic acid.
