This utility model discloses a sealing head structure and a battery, relating to the field of battery manufacturing technology. Specifically, it includes a heat-sealing head, a heat-insulating layer, and a cold-sealing head. The heat-insulating layer is connected to one side wall of the heat-sealing head; the cold-sealing head is connected to the side wall of the heat-insulating layer away from the heat-sealing head. The heat-insulating layer blocks heat transfer between the heat-sealing head and the cold-sealing head. This application uses a heat-insulating layer between the heat-sealing head and the cold-sealing head to block heat transfer, enabling the cold-sealing head to effectively cool and protect against the spread of heat radiation, thus protecting the inner layer of the aluminum-plastic film from damage. This significantly reduces process defects caused by heat radiation and avoids cell gas expansion caused by the inability to expel gas in time. It effectively improves the formation interface, avoids defects such as black spots or lithium plating during the formation process, and is beneficial for improving battery electrical and safety performance while reducing production costs.
