What are solid-state batteries? Solid-state batteries are a type of battery that uses solid electrolytes to replace traditional liquid or gel-type electrolytes. Compared to conventional lithium-ion batteries, solid-state batteries have a more stable structure, offering higher energy density, safer performance, and faster charging speed. The main problems with solid-state batteries: Technical Aspects Low ionic conductivity: The strong interaction between ions and high migration energy barriers in solid electrolytes result in lower ionic conductivity compared to liquid electrolytes, leading to slow charging and discharging rates and rapid capacity fading. Lithium dendrite growth: Even with solid electrolytes of high mechanical strength, it is difficult to completely inhibit the growth of lithium dendrites, which can form on the surface of the negative electrode and even penetrate through the solid electrolyte, causing battery short circuits. Solid-solid interface issues: The solid-solid interface in solid-state batteries has a small contact area, and volume changes during electrode charging and discharging can disrupt the interface structure, worsening contact, increasing interface impedance, and potentially causing chemical reactions to form unstable interface layers. Mechanical performance challenges: Solid materials in solid-state batteries are more prone to cracking when subjected to mechanical stress, such as during battery assembly or during vibrations or collisions in use, affecting battery performance and safety. Poor low-temperature performance: Solid-state batteries may experience more pronounced performance degradation in low-temperature environments, affecting their use in cold regions. Cost Aspects High material costs: Expensive materials such as lithium metal and special ceramic electrolytes, including high-priced lithium sulfide, are typically used, resulting in costs significantly higher than those of liquid lithium batteries. High manufacturing costs: The production process is complex, requiring precision processes and equipment, such as high-density stacking and high-precision electrolyte coating, as well as special production environments, with low production efficiency, leading to higher manufacturing costs. Environmental and Recycling Aspects Resource and energy consumption issues: From raw material extraction, processing, to manufacturing, significant natural resources and energy are consumed. The mining and refining of new materials can damage the environment, and the high energy consumption during production increases carbon emissions. Recycling challenges: The recycling and disposal of discarded solid-state batteries pose challenges. Their internal structures are complex, containing multiple metals and chemicals. Improper recycling can pollute the environment, and recycling technologies and processes are immature and costly.

On January 14, 2025, TOB NEW ENERGY organized a fire drill. Process Description: At 4 PM, a warehouse clerk discovered a fire in the warehouse. The fire was intense, prompting immediate alerting actions. The clerk organized the evacuation of warehouse staff and notified the general manager. The general manager swiftly mobilized all emergency response teams into position. (1) The warehouse supervisor secured the scene and brought along the emergency medical kit. (2) The emergency contact dialed 119 to report the fire. (3) The safety officer notified all relevant contingency plans. The main content of this fire drll was to simulate a warehouse fire and demonstrate how employees could self-rescue and evacuate after a fire breaks out, familiarize themselves with the use of fire-fighting equipment, and learn how to extinguish initial-stage fires. During the drill, employees covered their mouths with wet towels or hands, bent over, and quickly and orderly evacuated from the warehouse to the emergency assembly point. At the same time, they gained knowledge about fire safety and the use of fire extinguishers, and everyone personally operated a fire extinguisher.

TOB NEW ENERGY to All Employees and Valued Customers: As another year draws to a close and the holiday season is upon us, TOB NEW ENERGY would like to express our sincere gratitude to all our employees for their hard work and dedication throughout the year.

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...
