At the recent 2022 earnings presentation, global power battery leader CATL’s Chairman and General Manager Zeng Yuqun said that CATL's M3P battery is expected to be delivered in mass production this year. Zeng Yuqun said, "In the case of large-scale applications, M3P battery can reduce costs and increase efficiency, low-temperature performance, energy density better than lithium iron phosphate batteries, and cost better than ternary Li-ion batteries. Please see the subsequent release for the application on specific models. In an investor research event in February last year, CATL said for the first time that it planned to launch a new product M3P battery, but this product is not lithium manganese iron phosphate battery to be exact, the battery cathode material also contains other metal elements, which the company calls ternary lithium battery of phosphate system. Last August,CATL chief scientist Wu Kai, who attended the 2022 World Power Battery Conference last year, further explained, "M3P battery can be aimed at mid-range models with a range of about 700km. Previously for models with this range,CATL used medium and low nickel ternary cathode material solutions, which are relatively more costly. Combined with the 'Kirin battery' pack structure, M3P's new material can also meet the needs of such models." Wu Kai said.

Shenyang Securities research report analysis,CATL M3P battery may be doped with two of the metal elements such as magnesium, zinc, aluminum, etc., in part of the iron element point to form a replacement, thereby generating phosphate system of ternary materials to improve the charge and discharge capacity and cycle stability.

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.

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 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.

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 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.
