Spray drying is a method of applying systematic technology to material drying. After the thinner is atomized in the drying chamber, in contact with the hot air, the moisture rapidly vaporizes to obtain a dry product. This method can directly dry the solution and emulsion into powder or granular products, and can save the steps of evaporation and pulverization. Its working principle: through mechanical action, the material to be dried is dispersed into very fine mist-like particles (increasing the evaporation area of water, accelerating the drying process), and contacting hot air to remove most of the water in an instant. The solid matter in the material is dried into powder. Advantages of the Lab spray dryer: 1. The drying process is very fast. 2. It can be directly dried into powder. 3. Easy to change drying conditions and adjust product quality standards. 4. Due to instantaneous evaporation, the equipment material selection requirements are not strict. 5. There is a certain negative pressure in the drying room, which ensures the sanitary conditions during production, prevents dust from flying in the workshop, and improves product purity. 6. High production efficiency and few operators. 7. Large production capacity and high product quality. The spray volume per hour can reach several hundred tons, which is one of the larger dryers. 8. The spray dryer is easy to adjust, and the operating conditions can be changed in a larger range to control the quality indicators of the product, such as particle size distribution, moisture content, biological activity, solubility, color, fragrance, taste, etc. Thank you for reading!

Lithium battery materials mainly include: cathode material, anode material, battery separator, and battery electrolyte. 1. Among the cathode materials, the most commonly used materials are lithium cobaltate, lithium manganate, lithium iron phosphate and ternary materials (a polymer of nickel, cobalt and manganese). The positive electrode material occupies a large proportion (the mass ratio of positive and negative materials is 3: 1~4:1), because the performance of the cathode material directly affects the performance of the lithium-ion battery, and its cost directly determines the cost of the battery. 2. Among the anode materials, the current anode materials are mainly natural graphite and artificial graphite. The anode materials being explored include nitrides, PAS, tin-based oxides, tin alloys, nano-anode materials, and other intermetallic compounds. As one of the four major constituent materials of lithium batteries, anode materials play an important role in improving battery capacity and cycle performance, and are at the core of the middle reaches of the lithium battery industry. 3. The market-oriented diaphragm materials are mainly polyolefin separators based on polyethylene (PE) and polypropylene (PP). In the structure of the lithium battery, the seaparator is one of the key internal components. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. A separator with excellent performance plays an important role in improving the overall performance of the battery. 4. The electrolyte is generally prepared from high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials under certain conditions and in a certain proportion. The electrolyte plays a role in conducting ions between the cathode and anode electrodes of the lithium battery, which is the guarantee for the lithium ion battery to obtain the advantages of high voltage and high specific energy.

The battery tabs are a kind of raw material for lithium-ion polymer battery products. The battery tabs are the metal conductors that lead the cathode and anode from the battery cells and are the contact points during charging and discharging! The battery tabs are divided into three materials. The cathode electrode of the battery tabs use aluminum (Al) material as cathode aluminum tabs, the anode electrode uses nickel (Ni) material as anode nickel tabs, and the anode electrode also use copper-plated nickel (Ni-Cu) material as copper-plated nickel tabs, they are composed of two parts: tape-film and metal tape. Our company can provide various customized size battery tabs according to customer requirements. Please feel free to contact me if you have any needs. Thank you for reading!

Graphite has the advantages of high electronic conductivity, large lithium ion diffusion coefficient and small volume change of lamellar structure before and after Lithium intercalation, high lithium intercalation capacity and lithium intercalation at low potential. It has become the mainstream commercial lithium ion battery anode material. Today we will send out a batch of graphite material for lithium battery anode. Besides, TOB NEW ENERGY can provide all Cathode Materials, Anode Materials, Casing Materials, Battery Current Collectors, Conducive Materials, Graphene and Graphite Oxide, Binders, Battery Tabs, Battery Separator and Tape, Aluminum Laminate Film, Electrolyte, Pack Materials, Porous Metal Foam Materials, Nanomaterials and many others. Natural graphite and artificial graphite have been the largest battery anode materials used, However, due to the high temperature treatment in the process of production, the production cost of artificial graphite is greatly increased and has adverse effects on the environment. Compared with artificial graphite, natural graphite has many advantages, it has the advantages of low cost, high degree of crystallization, mature technology of purification, grinding and grading, low charging and discharging voltage platform and high theoretical specific capacity, all of which lay a good foundation for its application in lithium ion battery sector.
