Power battery summit held in Shanghai - November 21, 2024
第九届动力电池应用国际峰会在上海举行
The 9th International Summit on Power Battery Application (CBIS2024) was held in Shanghai from November 18 to 20, 2024. Themed "Innovation& Integration – For A New Era of Industrial Cooperation", the summit focused on the advanced technologies and products of the industry chain.
Top global experts and enterprise representatives from the battery and new energy industry gathered in Shanghai to jointly explore the new quality productive forces of the new energy industry. Lin Jian, chief scientist of Shenzhen BAK Power Battery Co Ltd, shared BAK's research and development progress on high-capacity cylindrical battery as well as deep insights into the future trend of battery technology.
In terms of cathode materials, high nickel ternary cathode materials are undoubtedly the key factor in promoting the advancement of high-capacity battery technology due to their comprehensive advantages such as high energy density, long life, and strong temperature adaptability. However, they have disadvantages such as microcracks, phase transitions, Li/Ni cation mixing, and reduced thermal stability, which degrades battery conductivity.
Lin demonstrated the results of BAK Battery's data on ion doping, surface coating, and other modification methods in his speech, and showed that these methods have significantly improved the performance and competitiveness of lithium batteries made of ternary materials.
Lin emphasized that the silicon-based anode plays a key role in high-capacity battery cell design and performance improvement due to multiple advantages, such as high theoretical specific capacity, low de-embedded lithium potentials, environmental friendliness, and abundant reserves. In the field of silicon-based anodes, BAK Battery's first-generation silicon products have evolved to the third generation, which has significantly improved efficiency. Currently, BAK Battery is working on the research and development of fourth-generation silicon-based anodes to effectively improve the performance and cycle life of batteries, thus empowering the industrial application of silicon-based anodes.
Lin also revealed the R&D progress of BAK Battery's latest generation of high-capacity cylindrical batteries. Through the research and development of cutting-edge materials, BAK Battery has further increased the capacity of 21700 battery to 6.5Ah, improving their cycling performance, reliability and efficiency.
