  • ELECTRODE ASSEMBLY, BATTERY CELL, BATTERY, AND METHOD AND APPARATUS FOR MANUFACTURING ELECTRODE ASSEMBLY
    Publication number: 20240014401
    Abstract: An electrode assembly includes a positive electrode plate and a negative electrode plate wound or stacked to form a bend region, and a barrier layer provided at the bend region. At least part of the barrier layer is located between the positive electrode plate and the negative electrode plate that are adjacent to each other, and is configured to prevent at least part of ions deintercalated from the positive electrode plate from being intercalated into the negative electrode plate in the bend region. A ratio of a thickness of the barrier layer to a porosity of the barrier layer is larger than or equal to 3.5 microns and smaller than or equal to 2000 microns.
