Yang Hongxin: Lamination technology + cobalt-free technology is the future trend of power batteries

On August 11-13, the 12th China Automobile Blue Book Forum with the theme of "DongYa" was held in Wuhan Antique. During the 3-day conference, many heavyweight auto industry professionals gave speeches and dialogues around 23 discussions.

He said that laminated technology and low and cobalt-free have become the trend of battery development. At the scene, Yang Hongxin, President of Honeycomb Energy, analyzed the layout of power batteries and future technology development routes.

In his view, the cobalt reserves are small and concentrated, with only 710 manufacturing and production companies with limited control, which is particularly easy to stop.

At the same time, the cobalt-free internal resistance is relatively high. "If the lamination technology is used, its internal resistance can be reduced by 5%. Therefore, the combination of the two technologies of lamination and cobalt-free can not only give play to the advantages of cobalt-free, but also Solve the pain points of cobalt-free."

"At the end of next year," lamination and cobalt-free, one is from the perspective of process manufacturing, and the other is from the perspective of material cost and safety. This is a fundamental future trend, which can meet all aspects of cost, efficiency, power, and life. Claim. "In June next year, Honeycomb Energy will bring cobalt-free batteries to the market and carry out installation and sales.

"Why do batteries suddenly ignite spontaneously? Why are they suddenly thermally out of control? What is the mechanism? We still have no way to fully understand." Finally, he pointed out that battery companies and vehicle companies still have relatively superficial understanding of battery mechanisms.
