Problems solved by technology

The thicker insulating tape itself takes up more internal space of the battery cell. Although many through holes are set on the base material, it will still cause a large loss of battery energy.

Embodiment Construction

[0026] The present application will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings. The "front", "rear", "left", "right", "upper" and "lower" mentioned in the text are all based on the placement state of the lithium-ion battery using the adhesive tape in the insulating tape machine in the accompanying drawings.

[0027] Such as figure 1 As shown, Embodiment 1 of the present application provides an insulating adhesive tape, which includes a base material 10 , a hard particle layer 20 and an adhesive layer 30 . Wherein, the substrate 10 serves as the main structure of the entire insulating tape, responsible for carrying the hard particle layer 20 and the adhesive layer 30 . At the same time, the substrate 10 provided in this embodiment has a microporous structure, and a large number of random micropores are distributed both on the surface and inside. Due to the microporous structure, the substrate 10 has good...

Abstract

The present application relates to the field of energy storage devices, in particular to an insulating adhesive tape and a lithium ion battery using the adhesive tape. The insulating tape includes a base material, a hard particle layer and an adhesive layer; the base material is a microporous structure, the hard particle layer is stacked on the surface of the base material, and the particles in the hard particle layer The particle diameter is greater than the pore diameter of the microporous structure of the substrate, the adhesive layer and the hard particle layer are combined or the adhesive layer and the hard particle layer are separately arranged, and the adhesive layer is stacked It is arranged on the side of the hard particle layer away from the substrate. The lithium-ion battery includes the insulating tape described above. The lithium-ion battery provided by the present application reduces the impact of the energy loss of the battery cell caused by the installation of the insulating tape.

Description

technical field [0001] The present application relates to the field of energy storage devices, in particular to an insulating adhesive tape and a lithium ion battery using the adhesive tape. Background technique [0002] Insulating tape is an auxiliary material for lithium-ion batteries. It is well known in the industry. It is often used at the welding points of the battery tabs, the cathode and anode overhangs, and the corresponding sections. The main purpose is to prevent burrs from passing through the diaphragm and causing short-circuit failure of the battery. In particular, the area where the anode (or negative electrode) dressing corresponds to the cathode (or positive electrode) current collector (such as Al foil) must be insulated, otherwise the risk of short circuit inside the cell will increase. At the same time, in order to ensure that the area where the anode corresponds to the cathode current collector is well insulated, it is generally necessary to apply a certa...
