Title:
POSITIVE ELECTRODE SLURRY, POSITIVE ELECTRODE PLATE, LITHIUM ION BATTERY, BATTERY MODULE, BATTERY PACK, AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/077299
Kind Code:
A1
Abstract:
Embodiments of the present application provide a positive electrode slurry, and provide a positive electrode plate comprising the slurry of the present application, a lithium ion battery, a battery module, a battery pack, and an electrical device. The positive electrode slurry comprises: a manganese-containing positive electrode active material and a positive electrode additive, wherein the positive electrode additive is a compound of formula (I), A is equal to B and is selected from any one of N, O, and S, and R1, R2, R3, R4, R5, R6, R7, and R8 are each independently selected from the group consisting of hydrogen and an alkyl group having 1-7 carbon atoms. The positive electrode slurry of the present application can greatly reduce deposition of manganese ions on the surface of a negative electrode material by effectively capturing the manganese ions, thereby slowing down attenuation of the capacity of a lithium-manganese oxide-based lithium ion battery in a cycle and storage process, prolonging the service life of the battery, and improving high-temperature cycle performance and high-temperature storage performance.
