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

The ternary material is lithium nickel cobalt manganese oxide Li(NiCoMn)O2, a ternary composite positive electrode material precursor product, which is made of nickel salt, cobalt salt and manganese salt. The ratio of nickel cobalt to manganese can be adjusted according to actual needs. The battery with ternary material as the positive electrode is safer than the lithium cobalt oxide battery. Lithium cobaltate and ternary materials are good cathode materials for lithium batteries, but their chemical properties are different. Therefore, for their different chemical properties, The field of application is also different. Applicable scope: power battery, small electric type TOB NEW ENERGY LIMITED is specialized in lithium battery,supercapacitor battery equipments and materials, provides high-quality products and the most professional technical services.

The lithium battery electrode is generally compacted by a rolling press machine, as shown in Fig. 1. In this process, the electrodes coated on both sides of the particle coating are fed into the gap between the two rolls, and the coating is applied under the action of the roll line load. After being compacted, the electrode will elastically rebound after the seam is slid out, resulting in an increase in thickness. Therefore, the roll gap size and rolling load are two important parameters, usually the roll gap is smaller than the final thickness of the electrode, or the load can cause the coating to be compacted. In addition, the magnitude of the rolling speed directly determines the holding time of the load on the electrode, and also affects the rebound of the electrode, which ultimately affects the coating density and porosity of the electrode.
