  • In 2023, The Production Capacity of Sodium-Ion Batteries Will Increase by 10x
    In 2023, The Production Capacity of Sodium-Ion Batteries Will Increase by 10x Mar 22, 2023
    According to the latest released data, sodium battery production capacity is only 2GWh by the end of 2022, and by the end of 2023, sodium battery production capacity is expected to increase to 21GWh, 950% year-on-year increase. 2023 is the first year of large-scale sodium-ion batteries, a number of listed companies cut into the sodium-ion battery track, CATL recently revealed that this year's sodium-ion battery will be industrialized.Sodium batteries have a good cost advantage, and the total cost of sodium batteries is 30-40% lower than that of lithium batteries. The White Paper on the Development of China's Sodium-Ion Battery Industry (2023) predicts that the actual shipment of sodium-ion batteries will reach 347.0GWh by 2030. The capacity of the hard carbon anode is related to the energy density of sodium-ion batteries, which is the biggest difficulty in the current industrialization of hard carbon. Anode material hard carbon manufacturers have successfully developed high-capacity, high-first-effect hard carbon materials and taken the lead in industrialization.

    When there is only a low content of CMC in the slurry without SBR, graphite particles agglomerate during the homogenization process and cannot be well dispersed. When the ratio of CMC to graphite is moderate, adding 1.0% to 4.5% of SBR to the slurry will cause SBR to adsorb on the surface of graphite, dispersing the graphite particles and reducing the viscosity and modulus of the slurry. When the amount of CMC is 0.7% to 1.0%, the slurry exhibits viscoelasticity, and continuous addition of SBR will not change the rheological properties of the slurry. Comparing the two mixing methods of adding SBR and CMC simultaneously and adding CMC first and then SBR, the results show that CMC plays a leading role in the dispersion of graphite in the slurry, and CMC preferentially adsorbs on the surface of graphite particles. In general, when the amount of CMC added is very low, the addition of SBR will adsorb on the surface of graphite particles, which has a certain impact on the dispersion of graphite. As the amount of CMC added increases, the amount of adsorption on the surface of graphite also increases, and SBR cannot adsorb on the surface of graphite, thus playing no role in the dispersion of graphite. When a certain amount of CMC is reached, the combined attraction of excess CMC that fails to adsorb on the surface of graphite particles becomes greater than the repulsion, which can lead to agglomeration between graphite particles. Therefore, CMC plays a crucial role in the dispersion of graphite negative electrode slurry. Email :tob.amy@tobmachine.com Skype :amywangbest86 Whatsapp/Phone number :+86 181 2071 5609

  • Ni-rich Layered Oxide Particle Materials for Lithium-ion Batteries
    Ni-rich Layered Oxide Particle Materials for Lithium-ion Batteries Mar 15, 2023
    Ni-rich Layered Oxide Particle Materials for Lithium-ion Batteries    The cathode material is one of the most critical components of the partial ion battery, and it is determined to deal with the system energy density and cost of the battery on the large grid. Pre-commercial cathode materials can be divided into three categories: Laminated structure Spinel structure Olivine structure Among them, the high nickel layered oxide cathode materials NCM and NCA (LiNixCoyMnzO2, LiNixCoyAlzO2, x + y + z = 1, x ≥ 60%) have high actual specific capacity (≥ 180 mAh/g), high operating potential (~3.7 V vs. Li+/Li) and low cost, thus becoming the focus of academic and industrial attention. hot spot.   For more information, please contact us: Email : tob.amy@tobmachine.com Skype : amywangbest86 Whatsapp/Phone number : +86 181 2071 5609

  • Different Stacking Processes for Prismatic Cell
    Different Stacking Processes for Prismatic Cell Mar 10, 2023
    Different Stacking Processes for Prismatic Cell The prismatic cell winding process is relatively simple and has a high production efficiency. Multiple monolithic pole groups are combined in parallel in the battery shell, and the arrangement of the pole groups is arranged in the thickness direction. However, the winding technology is applied to square batteries with large defects, such as low space utilization, easy denaturation of cells, uneven current distribution and large polarization. The battery pack is made of multi-layer positive and negative electrode sheets stacked in parallel, which can avoid the deformation of the pack in the winding design; reduce the ohmic polarization and dense polarization of the battery, and improve the charge/discharge multiplier performance. Under the same conditions, the stacking process can increase the energy density of the battery by 5%, increase the cycle life by 10%, and reduce the cost by 5%. Therefore, the trend of large modules and large cells, the stacked sheet is more advantageous than winding. However, the stacked sheet process has low production efficiency, high technical and investment threshold, stacked sheet technology has not been applied to the square battery field on a large scale. TOB NEW ENERGY Supply both winding machine and stacking machine for prismatic cell.

  • TOB Inert Gas Furnace
    TOB Inert Gas Furnace Mar 07, 2023
    Inert Gas Furnace Heat treatment equipment There are many types of atmosphere furnaces, which can be classified according to the atmosphere inside the furnace (F-exothermic, X-absorbing, YL-organic liquid cracking, D-nitrogen-based, A-ammonia preparation, M-charcoal N-Ammonia, the last Q indicates atmosphere) The characteristics of the atmosphere furnace is to pass a certain composition of artificially prepared atmosphere into the furnace at a given temperature to achieve certain heat treatment purposes, such as gas carburizing, carbonitriding and bright quenching, annealing, normalizing, etc. Atmosphere furnace mainly has the following characteristics. Sealing In order to control the atmosphere inside the furnace, to maintain the pressure inside the furnace, the furnace working space should always be isolated from the outside air, try to avoid leakage and inhalation of air, so the requirements of the furnace shell, masonry, furnace door and all external connecting parts such as fans, thermocouples, radiation tubes, push and pull feeders, etc. using sealing devices; in order to maintain a certain carbon potential inside the furnace, in addition to control the stability of the atmosphere components, but also the atmosphere of the furnace for automatic control . Therefore, a variety of control instruments are needed to continuously or periodically measure the furnace atmosphere and adjust the amount of gas supplied to the furnace. TOB NEW ENERGY can provide high temperature furnaces such as atmosphere furnaces, tube furnaces, sintering furnaces, etc. for the preparation of electrodes for battery manufacturing.

  • Battery Materials NMP Shipping from TOB New Energy
    Battery Materials NMP Shipping from TOB New Energy Mar 03, 2023
    Battery Materials NMP Shipping from TOB New Energy NMP, full name N-methylpyrrolidone, is a colorless and transparent liquid, and is one of the most commonly used auxiliary materials for lithium batteries. Generally speaking, auxiliary materials for lithium batteries mainly include solvents and binders. The main function of the solvent is to dissolve the positive and negative active materials, and the main function of the binder is to bond the active materials to the current collector. The amount of auxiliary materials is generally 2%-5%, compared with the cost of the four major materials (positive electrode, negative electrode, electrolyte and separator), the cost is relatively small, but the role is very imp ortant and cannot be ignored. Among them, PVDF (polyvinylidene fluoride) is the most commonly used cathode binder, while NMP is the most commonly used solvent, and they are usually used together. NMP can be miscible with water, PVDF, positive and negative electrode materials, etc., and is widely used in the preparation of lithium batteries. When making electrode sheets, NMP is used as a solvent to mix binders, positive active materials, conductive agents and other electrodes. The substances are fused together so that the binder is fully in contact with other substances and evenly distributed. NMP is used as a solvent, and its quality will directly affect the quality of slurry coating for lithium-ion batteries.
