Academic sharing: In situ ultrasound monitoring and OCV monitoring of electrolyte infiltration process in lithium batteries

Hello everyone! Today, I will bring you an academic paper sharing about lithium battery testing experiments. This paper is an important breakthrough made by the team of academicians Ouyang from Tsinghua University in the field of lithium battery testing, and is included in the internationally renowned academic journal Nano Energy with the journal number 104 (2022) 107874.

This paper mainly studies the importance and influence of open circuit voltage on battery performance during electrolyte filling process. Through the intelligent workstation provided by Qingneng Bochuang (Zhuhai) Technology Co., Ltd. in the lithium battery testing laboratory, the team successfully verified the important role of open circuit voltage operation monitoring in the safety of lithium batteries during the electrolyte filling process.
The intelligent workstation for lithium battery testing laboratory is developed by Qingneng Bochuang. It uses in-situ ultrasonic scanning and OCV monitoring technology to observe and analyze the electrolyte permeation process of batteries assembled with different partitions. Through precise experimental data and detailed analysis results, the paper clearly demonstrates the impact of open circuit voltage on battery performance during electrolyte filling process.

In addition to ultrasonic testing technology, X-ray tomography and neutron radiography are also used to monitor the injection process of electrolytes. However, these methods have limitations such as high cost, inconvenience, and harm to the human body. In contrast, the ultrasonic testing technology developed by Qingneng Bochuang is non-destructive, inexpensive, harmless to the human body, and has high sensitivity. It can be used to scan and test the internal state of batteries, such as gas, porosity, and electrode materials.

This study conducted an in-depth study on the open circuit voltage during the electrolyte filling process, which helps to further optimize the design and production process of lithium batteries. In the rapidly developing lithium battery industry today, such research results have important application value and significance.
As an internationally renowned academic journal, Nano Energy has strict requirements and review procedures for high-quality academic papers. The inclusion of this paper is not only an recognition of the research results of the Ouyang academician team at Tsinghua University, but also an affirmation of the intelligent workstation in the lithium battery testing laboratory of Qingneng Bochuang (Zhuhai) Technology Co., Ltd.

The publication of this research result will promote the development of the field of lithium battery testing, and is expected to provide important reference basis for improving the performance and safety of lithium batteries. We believe that with further breakthroughs and innovations in lithium battery technology, we will usher in more efficient, safe, and reliable lithium battery products.
Here, we sincerely congratulate the team of academicians Ouyang from Tsinghua University and the researchers from Qingneng Bochuang (Zhuhai) Technology Co., Ltd., and look forward to their continuous efforts and innovative breakthroughs in the field of lithium batteries. We also look forward to more academic research results to make greater contributions to the development of the lithium battery industry.
