On February 12th 2019, we send 1 ton of 918-II natural graphite powder to Indonesia. The natural graphite anode is processed from natural graphite. the domestic graphite reserves and production are abundant, and the mining cost is low. Natural graphite has a relatively complete graphite sheet structure and a high degree of graphitization, suitable for lithium ions to be deintercalated and shuttled therein. The disadvantage is that the natural graphite is not modified and the cycle performance is poor. A common solution is to spheroidize to reduce the particle size and specific surface area of natural graphite, which will reduce the side reaction of the natural graphite anode with the solvent during the cycle; Second, construct a core-shell composite structure, generally in modification The spheroidized natural graphite surface is coated with a thin layer of non-graphitizable carbon material (such as asphalt) to improve the stability of the anode material in the lithium battery; Finally, artificially modify or change the surface state of the natural graphite, the same can be To achieve stability and durability of a single natural graphite negative electrode.

The battery 21700 is a model of a cylindrical battery, specifically: 21 - the outer diameter of the cylindrical battery is 21mm; 700 - the height of the cylindrical battery is 70.0 mm. This is a new model developed to meet the requirements of electric vehicles for longer mileage and to improve the effective utilization of vehicle battery space. The same material, 21700 compared to the common 18650 cylindrical lithium battery, the battery cell capacity increased by 35%. Taking the 21700 battery produced by Tesla as an example, after switching from the 18650 model to the 21700 model, the battery cell capacity can reach 3 to 4.8 Ah, a significant increase of 35%.

The dV/dQ curve dV/dQ curve is an analytical tool that can analyze the loss of active lithium in lithium ion batteries. The peaks in the dV/dQ curve mainly reflect the phase transition of the active substances in the process of lithium immobilization and lithium removal. dV/dQ curve mainly reflects the phase change of positive and negative active substances in the charging and discharging process. According to the data, we can find out the phase transition corresponding to different characteristic peaks in the dV/dQ curve, and then according to the variation trend of the dV/dQ curve in the cycle or in the storage process, we can qualitatively infer the cause of the reversible capacity loss of lithium ion battery, providing a reference for the design of lithium ion battery. The dQ/dV curve The physical meaning of a dQ/dV curve is the volume of a material per unit voltage. We all know that lithium ion batteries have a voltage platform for both anode and cathode materials. A high negative capacity on the voltage platform means that there is a lot of capacity in a very small voltage fluctuation range, so it is a characteristic peak on the dQ/dV curve. Usually we think of each peak on the dQ/dV curve as representing an electrochemical reaction. Because the reaction potentials of different materials are different, the positions and heights of peaks in the dQ/dV curve will also be different. How to operate in TOB cell tester system 1. dQ/dV curve setting 2. Select the current display curve 3. View the curve to see if achieved the desired effect 4. Click the record-layer expand/collapse button 5. Data copy 6. Select the cycle range to copy
