Title:
ELECTRODE PLATE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/061136
Kind Code:
A1
Abstract:
Provided in the present application are an electrode plate and a preparation method therefor. The electrode plate of the present application comprises a current collector and an electrode plate material layer arranged on at least one surface of the current collector, wherein the electrode plate material layer comprises an active substance and an optional conductive agent, and comprises a compound of formula (I). The electrode plate of the present application has relatively high porosity, a more uniform pore distribution, better initial electrolyte infiltration effect and good electrolyte retention capacity, and has reduced initial polarization and decreased direct-current resistance (DCR), such that the performance of a battery containing the electrode plate can be improved.
