Cell thickness gauge

How it works:

The working principle of the battery thickness gauge is mainly based on the principle of mechanical contact measurement, ultrasonic measurement or electromagnetic wave measurement. Among them, the mechanical contact measurement measures the thickness of the cell surface by producing a fixed pressure and a highly parallel probe. Ultrasonic measurement calculates the thickness of the cell by transmitting ultrasonic pulse and receiving its echo. Electromagnetic wave measurement uses the propagation characteristics of electromagnetic waves in the cell to determine its thickness.

Main features:

High precision: The thickness gauge usually adopts advanced measurement principles and high-quality measurement components, which can achieve micron or even nanoscale measurement accuracy to ensure the accuracy of measurement results

High stability: Due to the use of stable measurement principles and components, the battery thickness gauge can maintain the stability and consistency of the measurement results during long-term use.

High efficiency: The cell thickness gauge is simple to operate and fast to measure, which can greatly improve the test efficiency. Some high-end cell thickness gauges are also equipped with auxiliary functions such as pedal pneumatic lifting devices, further improving the measurement efficiency.

Easy to operate: The operating interface of the cell thickness gauge is usually designed to be intuitive and easy to use for non-professionals. At the same time, some equipment also has the function of automatic calibration and automatic zero clearing, simplifying the operation process.

Application scenario:

Production line measurement: In the production line of lithium batteries, the cell thickness gauge is used to measure the thickness of the cell to ensure the consistency and quality of the product, which helps to find possible problems in the production process in time, and take corresponding measures to improve.

Quality control: In the quality control process of lithium batteries, the cell thickness gauge is used to sample the finished battery. By measuring the thickness of the cell, you can judge whether the quality of the battery meets the standard, so as to ensure the qualified rate and reliability of the product.

Research and development stage test: In the research and development stage of lithium batteries, cell thickness gauges are used to test the thickness and uniformity of cells of different materials and different structures under different working conditions. This provides important data support for optimizing cell design and improving battery performance.
