Abstract:
The present application relates to a binder compound of formula (I) and a preparation method therefor, and an electrode plate containing same. In formula (I), R1, R2 and R3 each independently represent an unsubstituted or substituted linear or branched alkyl group having 1 to 6 carbon atoms or an unsubstituted or substituted aryl group having 6 to 20 carbon atoms; R4 represents -COOM; R5 represents a bridging oxo group or a bridging imino group; each M independently represents one of Li, Na, K, Rb and Cs; Z represents a linear or branched alkylene group having 1 to 6 carbon atoms; m is an integer selected from 7600-47000; n is an integer selected from 1520-94000; and m/n = 0.1-10. The binder compound of the present application has good adhesion, is water soluble and chemically stable, has swelling properties, and can improve the ionic conductivity of an electrode plate and reduce polarization, thereby improving the cell performance of a secondary battery.
