Cross-linked SBR microsphere binder and preparation method thereof and lithium-ion battery containing the binder

Abstract

A cross-linked SBR microsphere binder and a preparation method, and a lithium-ion battery containing the binder, the cross-linked SBR microsphere binder has a porous cross-linked structure, the cross-linked SBR microsphere has a particle size of 10 nm-1 μm, and a porosity of 0.01%-40%, and a pore diameter of the pore is greater than 0 and less than or equal to 200 nm. The lithium-ion battery containing the binder has advantages of better rate performance, low temperature performance, fast charge performance, and long cycle performance, compared with a lithium-ion battery containing a conventional SBR binder.
