  • Solid-state Batteries and Their Main Materials
    Solid-state Batteries and Their Main Materials Jun 13, 2024
    What is a solid-state battery? The traditional lithium-ion battery includes four major components: positive electrode, negative electrode, electrolyte, and separator. A solid-state battery replaces the electrolyte with a solid electrolyte. Compared with traditional lithium-ion batteries, the key difference of solid-state batteries lies in that the electrolyte has changed from liquid to solid, with both safety and high energy density. Solid-state electrolyte batteries are the ultimate form of lithium and sodium batteries, which can completely solve safety issues and are undoubtedly the protagonist in the second half of the new energy market. The solid-state battery industry chain is roughly similar to that of liquid lithium batteries. The upstream includes raw materials, mining, machinery and equipment, and basic materials. The main difference between the two lies in the types of negative electrode materials and electrolytes. The positive electrode materials are almost the same. If it is fully developed into a full solid-state battery, the separator will also be completely replaced. The midstream of the industry chain is the processing and preparation process of battery packs, and the downstream application areas of the industry chain include new energy vehicles, energy storage systems, consumer electronics, etc. The advantages of solid-state batteries are: (1) Solid-state electrolytes are used to replace liquid electrolytes and separators. Solid-state electrolytes have a very high ignition point, which improves the thermal stability of the battery; (2) The voltage platform of solid-state batteries is 5V, higher than the 4.3V of liquid batteries, which can match high-voltage electrode materials, and the battery energy density and specific capacity are better than liquid batteries; (3) Solid-state electrolytes are not fluid, so there is no leakage, simplifying the battery pack design, reducing the weight and volume of the battery, and the energy density is expected to exceed 300Wh/kg. Solid-state electrolyte Solid-state electrolyte is the core component of solid-state lithium-ion batteries, which can serve as the separator and electrolyte of the battery at the same time. The core role of the electrolyte is to transmit Li+ between the positive and negative electrodes. Ideal solid-state electrolytes should have high ionic conductivity, low interface impedance, stable structure, high safety, high mechanical strength, and low price. Currently, based on different electrolytes, it can be mainly divided into polymer solid-state electrolytes and inorganic solid-state electrolytes. The representative system of the former is PEO polyethylene oxide; the latter is the oxide, sulfide, and halide systems. Cathode materials The main cathode materials for solid-state batteries are: Lithium Cobalt Oxide, Lithium Iron Phosphate, Lithium Nickel Cobalt Oxide, and Lithium Cobalt Aluminum Oxide. (1)Lithium Cobalt Oxide: A commonly used cathode material in lithium-ion ba...
  • The Dragon Boat Festival: A Celebration of Tradition and Culture
    The Dragon Boat Festival: A Celebration of Tradition and Culture Jun 07, 2024
    The Dragon Boat Festival, also known as the Duanwu Festival, is a significant holiday in China that is celebrated with much enthusiasm and reverence. It falls on the fifth day of the fifth lunar month, marking the arrival of summer and the beginning of the rice planting season. Beyond its agricultural significance, the festival is deeply rooted in history, legend, and cultural traditions. The festival is most famous for its connection to the ancient Chinese poet Qu Yuan. A loyal minister during the Warring States period, Qu Yuan was exiled by the corrupt court. Heartbroken and disappointed, he threw himself into the Miluo River. To prevent the fish from eating his body, the local people rowed boats and threw rice dumplings into the river. This tradition has evolved into the dragon boat races and the eating of zongzi (glutinous rice dumplings wrapped in bamboo leaves) that are synonymous with the Dragon Boat Festival today. The dragon boat races are a thrilling spectacle. Long, colorful boats, adorned with elaborate dragon heads and tails, are paddled by teams of muscular oarsmen. The competition is fierce, with teams striving to be the first to cross the finish line. The crowds cheer loudly, adding to the festive atmosphere. Zongzi, on the other hand, are a delicious treat enjoyed by people of all ages. The rice is wrapped in bamboo leaves and often flavored with ingredients like red bean paste, meat, or eggs. The wrapping process itself is an art form, requiring skill and precision. Once prepared, the zongzi are steamed or boiled until they are soft and sticky. In addition to dragon boat races and zongzi, the Dragon Boat Festival is also a time for family reunions and cultural exchanges. People gather together to share meals, sing songs, and tell stories about the festival's origins and traditions. It is a time to appreciate the beauty of nature and celebrate the rich cultural heritage of China. The Dragon Boat Festival is not just a holiday; it is a celebration of tradition, culture, and community. It reminds us of our history and roots while bringing people together in a spirit of joy and camaraderie. As the festival continues to be celebrated across the globe, it serves as a bridge between cultures, connecting people from different backgrounds through the shared traditions and values that underlie this ancient holiday.Every year on this day, the Chinese people will have a holiday to celebrate,Many companies also prepare gifts for their employees, and this year, TOB NEW ENERGY has chosen to prepare fruit gift boxes.

    What exactly is the role of kneading in the lithium battery slurry mixing process? May 28, 2024
    Generally speaking, the dry anode material preparation process can be broadly divided into the following steps: mixing, wetting, dispersing, and stabilizing, with the wetting stage typically requiring a slower rotation speed. The dispersing stage, however, (kneading refers to the operation of using mechanical stirring to uniformly mix paste-like, viscous, and plastic materials, including both dispersion and mixing of the materials. Simply put, stirring highly viscous materials can also be referred to as kneading, such as kneading in toothpaste. The wetting process generally does not belong to the kneading process, though this may vary depending on different companies' understanding.) often requires a certain shear force and high-speed rotation, with a linear speed exceeding 20m/s. The main purpose of lithium-ion battery slurry dispersion is to uniformly disperse active materials, conductive agents, adhesives, etc. in a solvent in a certain mass ratio to form a stable slurry with a certain viscosity, which is used for coating the electrode sheet. The technological goal of lithium-ion battery slurry making is to prepare for the electrode sheet production. The ideal slurry requirements for electrode sheets are: (i) the active material particles are finely and uniformly dispersed without agglomeration, the conductive agent particles form a thin layer and are dispersed to form a conductive network, and the maximum amount of active material particles are interlocked and connected on the current collector; (ii) the active material particles are preferably small to ensure that the battery has a high current density. Kneading process Kneading principle: The high-speed rotating stirring paddle uses the friction force generated by the surface inclined at a certain angle and the material to make the material move tangentially along the paddle surface. At the same time, due to the centrifugal force, the material is thrown to the inner wall of the mixing chamber and rises along the wall. When it rises to a certain height, it falls back to the center of the impeller due to gravity, and then is thrown up again. The combination of this upward movement and tangential movement makes the material actually in a continuous spiral motion state. Due to the high rotation speed of the paddle and the fast movement speed of the material, the particles moving quickly collide and rub against each other, so that the particles or agglomerated clumps are broken, and the temperature of the material also increases accordingly, which is conducive to the adsorption of various additives by the powder. Kneading operation generally has the following characteristics: Kneading operation is often accompanied by heating or cooling process. On one hand, the unit volume of the kneader needs to have sufficient heat transfer surface. On the other hand, the moving parts should be able to stably and quickly scrape off the material adhered to the heat transfer surface and send it back to the high...
