“2024 World Carbon Materials Conference was successfully held in Shenzhen from July 14 to 19, gathering over 600 scientists and industry professionals from more than 30 countries around the world. The conference, themed 'Exploring the Future with Carbon', explored the latest technologies and applications of carbon materials as well as future development trends through invited reports and roundtable discussions. It brought together over 230 top scientists from more than 30 countries and regions worldwide, who engaged in in-depth discussions on the latest research progress and application prospects across multiple fields including nanocarbon materials, graphite, diamond, porous carbon, energy storage conversion materials, environmental materials, bio-health materials, and electronic information materials through eight sub-forums. This promoted international academic exchanges and advanced the application and development of carbon materials in industrial sectors.”
At the conference, our company representative Zhang Zhiguo delivered a speech titled "Dynamic Monitoring and Evaluation of the State of Charge of Lithium Batteries Based on Ultrasonic Imaging Technology" in Hall C of the International Hall (Area I) at the Tsinghua International Center.
Zhang Zhiguo focused on introducing the latest progress of Qingneng Bocang in lithium battery monitoring technology, especially how to use ultrasonic imaging technology to achieve full-point dynamic monitoring and evaluation of the state of charge (SOC) of lithium batteries.
Lithium-ion batteries, as an indispensable energy storage device in modern life, play a crucial role in extending battery life and improving energy efficiency through performance monitoring and measurement. Traditional electrical testing methods, despite their widespread use, have limitations in multi-parameter monitoring and in the qualitative and locational assessment of the internal state of batteries. Qingneng Bocang's innovative technology, through ultrasonic imaging, is capable of dynamic monitoring across the entire spatial domain of the battery, offering an entirely new perspective for battery condition evaluation. Zhang Zhiguo conducted an in-depth analysis of the amplitude variations of ultrasonic waves during the battery's charging and discharging processes, exploring the relationship between the changes in the state of charge during these processes and the variations in ultrasonic wave amplitude. Additionally, he introduced how to assess the battery's SOC based on the ultrasonic signal data points across the entire spatial domain of the battery.
As a young researcher at Qingneng Bocang, Zhang Zhiguo has demonstrated remarkable research potential and professional talent in the field of new energy technology despite having just completed his master's degree. His research on lithium battery monitoring technology, especially the application of ultrasonic imaging technology, has made significant progress, offering new perspectives and methods for battery performance monitoring.
In terms of academic research, Zhang Zhiguo has demonstrated remarkable scientific research capabilities and a spirit of innovation. During his master's degree, he published four high-quality SCI academic papers as the first author, covering two cutting-edge research fields: supercapacitor materials and the recycling of lithium-ion batteries. The topics of his papers include the preparation of carbon nanotubes and FeCo metal composite materials and their application in supercapacitor electrodes, a review of the recovery of lithium and cobalt from spent lithium cobalt oxide batteries, an analysis of the structural impact of Co-vanadate cobalt-vanadium-based electrode materials, and research on the star-shaped morphology of Co3O4 electrode materials regulated by NH4F and VO(acac)2.
The appeal of the conference is not limited to theoretical discussions. The exhibition area has also attracted countless visitors. Here, numerous exhibitors showcased their latest achievements in the field of carbon materials, from graphene and carbon nanotubes to carbon fibers and their composite materials. Each exhibit carries the power of innovation and represents the future direction of the carbon materials industry.
