Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0027] In the related technology, the daily-used finished battery has a casing, and various components of the battery are arranged in the casing. In order to improve the energy density of the battery and the space utilization rate in the casing, it is necessary to accurately grasp the size of each component inside the battery , in order to design and produce finished batteries with energy density and space utilization that meet the requirements.

[0028] The current measurement method is to fir...

Abstract

The embodiment of the invention discloses a battery diaphragm thickness measurement method and device, electronic equipment and a storage medium. The method comprises the steps of determining a to-be-measured unit composed of a diaphragm, a positive pole piece and a negative pole piece in a battery, then obtaining the thickness of the positive pole piece and the thickness of the negative pole piece in the to-be-measured unit, then measuring the thickness of the to-be-measured unit, and finally determining the thickness of the diaphragm according to the thickness of the to-be-measured unit, the thickness of the positive pole piece and the thickness of the negative pole piece. In the embodiment of the invention, the to-be-measured unit is determined in the battery, the thicknesses of the positive pole piece and the negative pole piece in the to-be-measured unit are firstly determined, then the thickness of the to-be-measured unit is obtained, and the thickness of the battery diaphragm is accurately measured by subtracting the thicknesses of the positive pole piece and the negative pole piece from the thickness of the to-be-measured unit.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a method, device, electronic equipment and storage medium for measuring the thickness of a battery diaphragm. Background technique [0002] In the prior art, lithium-ion batteries are widely used due to their high energy density, good cycle performance, high voltage, no memory effect, and environmental friendliness. For example, mobile phones, computers, electric vehicles and other equipment can use lithium-ion batteries. The existing battery technology is not enough to meet people's demand for battery performance. The battery capacity in the device is often increased by increasing the energy density of the battery. Therefore, it is necessary to obtain the size of each component inside the battery. [0003] However, the compression process of the battery during the production of the battery will cause the volume of some components inside the battery to change, which w...
