The battery piece comprises a substrate, and the surface of the substrate is provided with an N-type doped layer, a P-type doped layer and an isolation region arranged between the N-type doped layer and the P-type doped layer; the N-type doping layer and the P-type doping layer are arranged in an interdigital manner, each of the N-type doping layer and the P-type doping layer comprises a main body part and a finger-shaped part, the main body parts extend along a first direction, and the finger-shaped parts are arranged on at least one side of the main body parts along a second direction; the finger-shaped part is provided with a current collection electrode extending along a second direction; the first insulating layer is arranged at the position, close to the main body part of the opposite conductive type, of the finger-shaped part; the first insulating layer covers the end portion of the collector electrode, and the first insulating layer and the adjacent isolation region are arranged at an interval in the second direction. The first insulating layer is utilized to play an insulating and isolating role, meanwhile, the shielding area of the first insulating layer on the surface of the substrate is reduced, and the problem of poor local connection of the interconnector caused by the fact that the interconnector is heightened due to the fact that the first insulating layer partially extends below the interconnector can also be avoided.

This utility model relates to the field of aluminum electrolytic capacitors and discloses an aluminum electrolytic capacitor with a novel lead-out structure. The capacitor includes a capacitor body with a sealing layer fixedly connected to its outer wall. A lead-out terminal assembly is disposed at the bottom of the capacitor body. The lead-out terminal assembly includes an anode terminal and a cathode terminal, both of which adopt a segmented structure, including an internal connecting section, a sealed transition section, and an external connecting section. The internal connecting section is welded to the internal electrodes of the capacitor body, and the sealed transition section penetrates the sealing layer at the bottom of the capacitor body. In this utility model, the segmented design improves connection stability, and the flat, bent design increases the heat dissipation area, thus achieving applicability to various electronic devices and demonstrating good application prospects. It avoids problems such as poor sealing, poor heat dissipation, and inconvenient installation associated with traditional lead-out structures, thereby improving the practicality of the aluminum electrolytic capacitor with the novel lead-out structure.
