Abstract: A flexible battery includes a plurality of electrode assemblies, an electrical connector, elastic insulation members, and a package bag. The electrical connector is electrically connected to two adjacent electrode assemblies. The elastic insulation members are disposed at two end terminals of the electrical connector and have a gap with the electrode assemblies. The package bag is provided with a first dent accommodating the electrode assembly and the elastic insulation member, and a second dent accommodating the electrical connector. In the flexible battery, stress concentration caused by bending after packaging can be effectively reduced, so the package bag and electrical connector of the flexible battery are not prone to fracture, providing effective protection for the electrode assemblies, improving service life of the flexible battery, and ensuring stable performance and safety of the flexible battery.

Abstract: An electrode assembly includes a first electrode plate, a separator, and a second electrode plate that are disposed in a stack. The first electrode plate and the second electrode plate respectively have coating areas and empty foil areas arranged at intervals. Centers of the coating areas overlap each other to form a coating portion of the electrode assembly, and centers of the empty foil areas overlap each other to form a flexible portion of the electrode assembly. The first packaging layer coats the coating portion and the flexible portion of the electrode assembly, and the second packaging layer at least coats the first packaging layer on the flexible portion.
