The aim of this study was to determine the elastic modulus of the entire electrode by the ultrasonic method. It was found to have significant advantages over conventional tests, especially in the assessment of elastic modulus for components with complex geometries. The method enabled the use of a thin ultrasonic transmitter and receiver transmitted on the surface of the electrode, could generate a short pulse period of time, and the elastic modulus greater than the non-destructive nature of the conventional test relative to the. The elastic modulus was measured by the Ultrasonic longitudinal wave technique. The results obtained in this study showed that the elastic modulus of the entire electrode was significantly higher than that of the reference material. This is because the ultrasonic method could detect the cracks and other imperfections in the material, which are not always detectable by conventional tests. Moreover, the ultrasonic method was found to be cost-effective and time consuming.

Introduction

The elastic modulus is an important parameter of a material, which quantifies the resistance of the material to elastic deformation as a function of applied tensile or compressive load. It is a fundamental measure of the response of a material to external stress. The application of this parameter is essential in the design and manufacturing of components used in a variety of engineering applications.

Conventional tests for determining the elastic modulus involve either destructive techniques or destructive techniques that involve significant risk of damage to the material. For example, testing machines that are used to measure the elastic modulus of a material involve applying a load to the material to determine its resistance to deformation. However, in many cases the applied load can cause permanent damage to the material.

In contrast, the ultrasonic method has been found to be a fast and non-destructive alternative to conventional tests when measuring the elastic modulus of a material. The ultrasonic method requires the use of a transmitter and receiver to send and receive an ultrasonic wave on the surface of the material in order to determine the elastic modulus. This method requires the use of a thin ultrasonic transmission line so that the pulse rate could be kept within a short period of time, while the receiver can detect the properties of sound waves upon reflection and transformation into electrical signals.

In this study, an ultrasonic longitudinal wave technique was used to determine the elastic modulus of the entire electrode. Then, the elastic modulus of the entire electrode was compared to the reference material.

Materials and methods

In this study, an ultrasonic longitudinal wave technique was used for the investigation of the elastic modulus of the entire electrode. This method involves a thin ultrasonic transmitter and receiver connected to the end of the electrode. The transmitter and receiver were then connected to a digital oscilloscope. The digital oscilloscope was used to measure the amplitude of the received signal. The received signal was then compared with the transmitted signal in order to determine the elastic modulus of the entire electrode.

Results and discussion

The results obtained in this study showed that the elastic modulus of the entire electrode was significantly higher than that of the reference material. This is due to the fact that the ultrasonic method is able to detect the presence of cracks and other imperfections in the material, which are not always detectable by traditional methods. Moreover, the elastic modulus obtained using the ultrasonic method was higher than the non-destructive nature of the conventional test.

Conclusion

In this study, the ultrasonic longitudinal wave technique was used to determine the elastic modulus of the entire electrode. It was found to have significant advantages over conventional tests, especially in the assessment of elastic modulus for components with complex geometries. The method enabled the use of a thin ultrasonic transmitter and receiver transmitted on the surface of the electrode, could generate a short pulse period of time, and the elastic modulus greater than the non-destructive nature of the conventional test relative to the. Moreover, the results obtained showed that the elastic modulus of the entire electrode was significantly higher than that of the reference material, indicating the capability of the ultrasonic method to accurately measure the elastic modulus of complex geometries. In conclusion, ultrasonic techniques can be an effective and cost-effective alternative for the determination of the elastic modulus of components with complex geometries.

Determination of Elastic Modulus of Whole Electrode by Ultrasound Method

Ultrasound technology has been used to measure the elastic modulus of materials for many decades. Previous studies have focused on measuring the Young’s modulus of steel, ceramics and polymers by direct contact ultrasound. Recently, ultrasound has been utilized to measure the elastic modulus of whole electrodes from Li-ion batteries. This method does not require physical contact between the transducer and the sample, which is ideal for applications where contact between the two is difficult.

The principle of this method is to measure the elastic modulus of the sample by measuring the oscillations of the ultrasonic signals received back from the sample. An ultrasonic transducer is used to send ultrasonic waves of known frequency through the sample material. When these waves reach the sample, they are reflected back to the transducer as a result of the elastic properties of the sample material.By measuring the return signals and their associated frequency, the elastic modulus of the sample material can be determined.

It is important to note that the technique is only capable of measuring the elastic modulus of surface layers of the sample, making it suitable for applications such as measuring the elastic modulus of the whole electrode of a Li-ion battery. An additional advantage of this method is that the measurements can be made in situ, which means that the measurements are made at the same place where the sample material is being used.

In conclusion, the ultrasound method is an effective and convenient way to measure the elastic modulus of the whole electrode. It is capable of making measurements in situ, so it is a useful tool for researchers to analyze their sample materials without the need to remove them from their application.
