COMPOSITE BINDER, POSITIVE ELECTRODE OF LITHIUM RECHARGEABLE BATTERY APPLYING COMPOSITE BINDER, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2016/082658
Kind Code:
A1
Abstract:
The present invention relates to a composite binder, comprising an organic-inorganic hybrid polymer and a fluorinated binder that are evenly mixed, where each repetitive unit of the organic-inorganic hybrid polymer comprises a silicon atom, a methacryloyloxy group or a acryloyloxy group, and at least two alkoxy groups, and the alkoxy group and the methacryloyloxy group or the acryloyloxy group are respectively connected to the silicon atom. The present invention further provides application of the composite binder in a positive electrode of a lithium rechargeable battery, so as to improve electrochemical cycling performance of the lithium rechargeable battery.
