Title:
BINDER AND ELECTROCHEMICAL ENERGY STORAGE DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/068268
Kind Code:
A1
Abstract:
A binder and an electrochemical energy storage device thereof. A binder comprises a first component and a second component that are separated from each other. The first component comprises at least one compound comprising a first reactive functional group. The first reactive functional group is selected from at least one of an epoxy group and an isocyanate group. The second component comprises at least one polymer comprising a second reactive functional group. The first reactive functional group reacts with the second reactive functional group to form a chemical bond. A three-dimensional cross-linked structure is generated by using the chemical reactivity between the first reactive functional group and the second reactive functional group. The intensity of the three-dimensional cross-linked structure is far higher than that of common physical binding. It is especially suitable for preparation of an electrode plate in a secondary battery, and can improve the adhesive force and the cohesiveness of the electrode plate, reduce rebound after cold pressing and expansion of the electrode plate during a recycling process, and improve the energy density.
