Resumen de: WO2026179026A1
The present application discloses a battery module. The battery module comprises a battery cell stack, a frame, heating films, and a cover plate. The frame defines a mounting space having an opening at the top, and the battery cell stack is disposed in the mounting space. The heating films are disposed on the top of the battery cell stack, and the heating films are used for heating the battery cell stack. The cover plate covers the top of the frame and seals the opening, and the cover plate is in contact with the side surfaces of the heating films facing away from the battery cell stack. The heating films are disposed inside the battery module, and the heating films are directly disposed on the top of the battery cell stack; thus, heat generated by the heating films can be directly conducted to the battery cell stack, thereby reducing the loss during a heat conduction process and improving the heating efficiency.

Resumen de: WO2026182174A1
This secondary battery comprises: a positive electrode; a negative electrode; a separator disposed between the positive electrode and the negative electrode; a spacer disposed between the positive electrode or the negative electrode and the separator; and an electrolyte solution. The spacer includes a first resin and a second resin. The first resin has a degree of swelling with respect to the electrolyte solution of 1.1 times or more, and the second resin has a degree of swelling with respect to the electrolyte solution of less than 1.1 times. The spacer changes the abundance ratio of the first resin to the total of the first resin and the second resin in a direction perpendicular to the thickness direction of the spacer.
