Zusammenfassung:	An electrode core, a battery apparatus, and an electronic device are provided. The electrode core includes a negative electrode sheet, a negative electrode tab, and a positive electrode sheet. The negative electrode sheet includes a negative electrode current collector and a negative electrode active material attached to the negative electrode current collector. A negative electrode tab groove is provided on the negative electrode active material. The negative electrode tab is arranged in the negative electrode tab groove. The positive electrode sheet includes a positive electrode current collector, and a positive electrode active material attached to the positive electrode current collector. A first groove arranged opposite to the negative electrode tab groove is provided on the positive electrode active material, and a projection of the first groove on the negative electrode sheet is located in the negative electrode tab groove.
