Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0080] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0081] The terms "first", "second" and the like in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0082] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0083] The term "plurality" used in this application refers to two or more (including two).

[0084] In this application, the battery may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, etc., and the embodiments of this application are not limited thereto. The battery may be flat, rectangular, or in other shapes, and the embodiments of this application are not limited thereto.

[0085] A battery includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. Battery cells operate primarily through the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive electrode current collector, and the current collector uncoated with the positive active material layer serves as the positive electrode tab. For lithium-ion batteries, for example, the positive electrode current collector can be made of aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative electrode current collector, and the current collector uncoated with the negative active material layer serves as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative active material can be carbon or silicon, among others. To ensure that high currents can be passed without melting, multiple positive electrode tabs are stacked, and multiple negative electrode tabs are stacked. The material of the isolation film can be PP (polypropylene) or PE (polyethylene).

[0086] Batteries have outstanding advantages such as high energy density, low environmental pollution, high power density, long service life, wide adaptability, and low self-discharge coefficient. They are an important part of the development of new energy today. As the new energy industry develops, the requirements for battery preparation are also becoming increasingly higher.

[0087] During the lithium-ion battery manufacturing process, the batteries need to be restrained to facilitate installation, testing, and other operations. For example, the formation process, a crucial step in lithium-ion battery manufacturing, primarily involves the initial charging of the battery cell to activate the lithium-ion battery. During this process, the solvent in the battery's electrolyte and the lithium salt undergo a side reaction, forming a layer of SEI (Solid Electrolyte Interface) film at the negative electrode of the lithium-ion battery. The quality of the SEI film directly affects the battery's cycle life, stability, and electrical properties such as self-discharge. Simultaneously, the solvent and some additives in the electrolyte are reduced or decomposed, causing significant gassing within the battery. If the gas generated during formation is not promptly discharged, it can lead to battery bulging and reduced group margin. The electrolyte in the battery will not fully penetrate the negative electrode, resulting in the formation of dried, unintercalated black spots. Lithium deposition can also occur around these spots. Furthermore, lithium ions released from the positive electrode can easily form around the bubbles, further affecting the battery's electrical performance. By restraining the battery and applying pressure to the battery so that the gas can be discharged in time, the impact of the gas on the battery during the formation process can be mitigated.
