IEST Participate 2021, the National Powder Materials and Efficiency Auxiliary Material Innovation and Forum
From November 23 to 25,2021, the National New Energy Powder Materials and Efficiency Auxiliary Material Innovation and Development Forum was successfully held in Guangdong · Shenzhen. IEST exhibit powder resistivity instruments in Innovation and Forum.
With the rapid development of modern high-tech and new material industry, powder application technology has become an important factor affecting the performance of new materials and the quality of industrial products, and is closely related to the development of all walks of life.The conference gathered outstanding experts and outstanding enterprise personnel from all over the country to summarize and look forward to the development situation and trend of powder materials in the new energy industry.
With the rapid development of lithium industry, lithium-ion batteries have been widely used in mobile phones, computers, automobiles, energy storage and other fields. Users have fast charging requirements higher and higher, and the corresponding doubling performance requirements of battery are higher and higher.The performance of lithium-ion battery is closely related to the battery resistance. In the actual battery development and production process, the ion resistance part needs to be evaluated at the finished end of the battery, and the electronic resistance part can be quickly evaluated in the material and the pole end. Therefore, the accurate evaluation of the material and the electronic resistance of the finished cell is important.
IEST laboratory director-Qi Qiongqiong was invited to the conference speaker, at the meeting on the lithium positive and negative powder resistivity test and its impact on battery performance, the report introduces the powder, slurry, pole plate three levels of resistance characterization method, and the resistance on the impact of battery performance, and comprehensive analysis of resistance correlation of different levels, by regulating the resistance to improve the battery performance.
In addition, as the sponsor of the conference, IEST participated with the special battery materials and core performance testing instruments in the lithium battery industry, including: powder resistivity & compaction density meter, slurry resistor, pole chip resistor, in-situ gas production volume monitor, in-situ swelling analysis system. Through the on-site communication with the participants, we showed to our customers the innovative characterization technology and detection methods of powder materials in the field of new energy, and won the high attention and recognition from many participants.
