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, due to their characteristics, they have disadvantages, such as microcracks, phase transitions, Li/Ni cation mixing, and reduced thermal stability, which degrades battery conductivity. In this regard, Dr. Lin Jian 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.

As for anode materials, Dr. Lin Jian 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 first 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.

Finally, he 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 2170 battery to 6.5Ah, greatly improving their cycling performance, reliability, and efficiency, and thus bringing a better experience to users.
