The working principle of lithium-ion battery and the assembly process is introduced

Source: 2020 - 03 - 24 now hits: we all know, lithium ion battery anode data is lithium cobalt oxide, data is carbon cathode. The working principle of lithium-ion battery is charging and discharging. When batteries, lithium ions in the cathode of the battery, the lithium ions move through the electrolyte to the anode. More negative carbon layer structure, pore. In carbon pore embedded in the lithium ion, the more the higher the charge capacity. Similarly, when the battery discharge ( That is to say, we use the battery process) , the lithium ion in anode carbon layer embedded can come out and move back to the anode. Lithium ion to return to the positive, the more the greater the discharge capacity. We usually say the battery capacity is refers to the discharge capacity. It is not hard to see, in the process of charging and discharging lithium ion batteries, lithium ion in from the positive to the negative to the positive motion state. If we compare the lithium ion battery and rocking chair, the poles of the rocking chair at both ends is battery, lithium ion is like a good athlete, running to and fro in the ends of the rocking chair. Therefore, the experts to lithium ion battery has a lovely name: rocking chair batteries. Working principle of lithium-ion batteries and assembly process tools/source data cathode material of anode material separation steps/methods 1 paper pulping: will be positive and negative active material powder mixed with special solvent and adhesive, high speed stirring, form the positive and negative material paste. Layer 2: the preparation of good paste evenly coated on the surface of metal foil, the preparation of the positive and negative. 3 assembly: according to the positive plate - Clearance - Negative plate - The diaphragm placed from top to bottom, winding battery core, and then complete the electrolyte injection process, the battery assembly process is completed. Battery input products. 4 input: use special battery charging and discharging device to product battery charging and discharging test, to test each battery, battery select qualified product delivery. Matters needing attention of lithium ion battery technology is very strict and trival, here is a brief introduction.
