[China's research and development of new lithium battery cathode materials can improve fast charging efficiency and durability] On October 2, the scientific research team of the Shenyang National Research Center for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, proposed a new strategy for cathode material design based on the laws of physical and chemical interactions of trace elements, promoting the exploration of cathode materials from "experience trial and error" to "goal-oriented". The relevant results were published in the international academic journal "Nature·Synthesis" on October 1. In response to the two problems of "lithium ions run slowly" and "the material structure is unstable", the scientific research team proposed a more targeted element screening method based on the underlying physical and chemical mechanisms: one type of elements is responsible for making lithium ions run more smoothly, and the other type of elements is responsible for making the material structure stronger. These two effects are closely related to the ionic charge density and metal-oxygen bonding strength of the element respectively. Elements with lower charge density can reduce the obstacles encountered during the migration of lithium ions, making it easier for lithium ions to move quickly in the material; elements that combine more firmly with oxygen can enhance the stability of the crystal skeleton, making the material less likely to undergo structural damage during repeated charge and discharge processes.

[Geely Holding Group and NIO have reached a strategic cooperation to jointly build a battery charging and energy replenishment ecosystem] On September 28, Geely Holding Group and NIO reached a strategic cooperation today. The two parties will further deepen the implementation of strategic cooperation in the field of charging and swapping, integrate their respective advantageous resources in the fields of charging and swapping infrastructure construction, technology research and development, operation services, etc., jointly promote the open sharing and industrial collaboration of China's new energy vehicle charging and swapping system, and accelerate the scale and market-oriented development of the charging and swapping system. On September 23, Geely Automobile Group officially released the new generation AI energy replenishment technology "Geely Smart Charging". Relying on the industry's first full-scale energy model "Xing Rui PowerMind Energy Brain" jointly developed by Geely and Step Star, it can achieve a peak charging power of 2.2 megawatts (2250 kilowatts) per gun, the maximum temperature is always lower than 65°C, and the battery cycle life is increased by more than 20%. The signing of a strategic cooperation framework agreement between Geely Holding and NIO is a key move for Geely to further open up and collaborate on AI smart charging capabilities and battery swap ecology under the strategy of "all-area AI, all-area security".
