The long-range and fast-charging capabilities of electric vehicles rely on high-performance lithium-ion batteries, with cathode materials being one of the most crucial components. However, cathodes are prone to cracking during cycling and exhibit persistent side reactions with electrolytes, significantly compromising the battery's cycle life and rate performance. Surface coating can mitigate stress, enhance the wettability of liquid electrolytes, reduce interfacial charge transfer resistance, and decrease side reactions, thereby effectively optimizing cathode materials. Nevertheless, the influence of the physicochemical properties of surface coatings on electrochemical performance, as well as their evolution during cycling, still requires further understanding. Additionally, the optimal surface coating materials and methods have not been systematically summarized and concluded. 1. Requirements for Cathode Surface Coating The requirements for surface coating include: 1) being thin and uniform; 2) possessing ionic and electronic conductivity; 3) having high mechanical properties and remaining stable after charging/discharging cycles; 4) the coating process being simple and scalable. 2. The Roles of Surface Coating on Cathode Materials The roles of surface coating on cathode materials include: 1) serving as a physical barrier to inhibit side reactions; 2) scavenging HF to prevent chemical attack by the electrolyte and mitigate the dissolution of transition metals; 3) enhancing electronic and ionic conductivity; 4) modifying surface chemistry to facilitate interfacial ion charge transfer; 5) stabilizing the structure and reducing phase transition stress. 3 Coating Structure/Morphology 3.1 Uniform and Thin Coating The coating layer should be uniform and thin. Complete coverage of the cathode particles will protect the cathode from electrolyte attack and inhibit side reactions. Additionally, a thin coating layer enhances the kinetics at the interface, improving battery performance. 3.2 Thick Coating A thick coating provides a good physical barrier between the cathode and the electrolyte. However, thicker coatings can hinder the diffusion of lithium during intercalation and deintercalation processes, potentially performing well under high-temperature operations. 3.3 Island-Like/Rough Coating Layer Achieving a uniform and thin coating across the entire material using dry and wet coating processes is challenging. The coating layers formed by these processes are rough and uneven. 4. Coating Processes/Strategies 4.1 Wet Processes 4.1.1 Sol-Gel Coating The sol-gel coating process is commonly used for synthesizing cathode materials and surface coating. However, the use of water or other solvents increases costs. Additionally, solvents like water can cause lithium leaching and alter the stoichiometry of the cathode surface. 4.1.2 Hydrothermal/Solvothermal Coating The coating layers developed through hydrothermal/solvothermal processes are nanoscale and uniform...

Among the myriad of traditional festivals in China, the Mid-Autumn Festival stands out with its unique cultural connotations and rich celebratory activities, becoming a significant moment for families to gather under the bright moon and express their yearning and thoughts. Within this warm and reuniting festival, a highly localized folk activity – Boling, adds a touch of laughter, joy, and a profound festive atmosphere to the occasion. The Origin and Significance of Boling Boling, also known as "Pabo", is an indispensable traditional custom during the Mid-Autumn Festival in the southern Fujian region, particularly in Xiamen and Quanzhou. According to legends, this custom originated from the ancient imperial examination system, symbolizing people's aspiration to win the top rank of zhuangyuan (the imperial first-degree scholar) through the game, thereby bringing honor to their families. As time passed, Boling gradually evolved into a folk game integrating entertainment and blessings, becoming a vital activity during Mid-Autumn gatherings among friends and relatives. The Rules and Delight of Boling The equipment for Boling is a special set of six dice, each face of which is inscribed with different prize levels ranging from "Yixiu" to "Zhuangyuan Chajinghua". Participants take turns rolling the dice, and the resulting points and combinations determine the prize they win. From the modest joy of "Yixiu" to the exhilarating cheers for "Zhuangyuan Chajinhua", each prize represents different good fortune and blessings. The joy of Boling lies not only in winning the grand prize but also in the thrilling tension and laughter throughout the process. Whenever someone rolls a high score, the crowd erupts in cheers; occasional "funny" rolls evoke a wave of good-natured laughter. This relaxed and joyful atmosphere makes the Mid-Autumn reunion even warmer and more harmonious. The Cultural Value Behind Boling Boling is more than just a simple game; it carries profound cultural values and emotional attachments. In playing Boling, people not only enjoy the fun of the game but also convey their aspirations for a better life and pursuits. This activity deepens familial bonds and strengthens neighborhood friendships. Additionally, Boling embodies the optimistic and challenging spirit of the people of southern Fujian, as well as their commitment to preserving and promoting traditional culture. To uphold traditional culture and foster communication and team cohesion among employees, the Xiamen TOB Boling event was successfully held on September 13, 2024. The Boling activity was organized into several groups, with members randomly selected from different departments, aiming to bridge departmental gaps and promote cross-departmental collaboration and exchange. During the event, employees took turns rolling the dice, each roll captivating the hearts of all present. From the pleasant surprise of "Yixiu" to the enthusiastic cheers for "Zhuangyuan," every prize announcement ...

Controlling the uniformity of lithium battery coating involves multiple factors across various aspects such as personnel, machinery, materials, methods, and environment. However, the fundamental factors are directly related to the coating process conditions, including the coating substrate, adhesive, coating steel roller/rubber roller, and the laminating machine. 1.    Coating Substrate: Key factors are the material type, surface properties, thickness, and its uniformity. 2.    Adhesive: Main considerations are its working viscosity, affinity, and adhesion to the substrate surface. 3.    Coating Steel Roller: As the direct carrier of the adhesive and the supporting benchmark for the coating substrate and rubber roller, it is the core of the entire coating mechanism. Factors like geometric tolerance, rigidity, dynamic and static balance quality, surface quality, temperature uniformity, and heat deformation affect coating uniformity. 4.    Coating Rubber Roller: The rubber roller is an essential variable for coating quality. Its material (e.g., durability of the rubber layer), hardness, geometric tolerance, rigidity, dynamic and static balance quality, surface quality, and heat deformation also influence coating uniformity. 5.    Laminating Machine: It serves as the foundational platform for coating. In addition to the precision and sensitivity of the coating steel roller and rubber roller pressing mechanism, it also encompasses the design operating speed and overall machine stability. The influencing factors for coating uniformity differ in the lateral and longitudinal directions, necessitating different control measures. These measures relate to both the design and manufacturing of the machine, as well as operational and process control. In practice, ensuring uniform coating involves both technical adjustments to the machinery and precise operational procedures. Lateral Uniformity of Coating and Its Control The uniformity of coating in the width direction is primarily influenced by the following factors: Geometric tolerance of steel rollers and rubber rollers. Contact pressure between steel rollers and the substrate. Lateral distribution of the adhesive, primarily referring to the viscosity of the adhesive and its corresponding transfer rate. This is comprehensively determined by the first two factors and the working viscosity of the adhesive. The primary benchmark for ensuring coating accuracy is the geometric tolerance and rigidity of the steel roller. During operation, the geometric tolerance, rigidity, balance precision, assembly precision, and built-in heating and insulation system of the steel roller directly affect the state of the adhesive, thereby influencing the transfer rate and coating uniformity. Therefore, designing and selecting high-precision, wear-resistant steel rollers is a fundamental task. Rubber rollers, especially the coating...
