锂离子电池工作原理(国外英文资料) The working principle of lithium ion battery charging refers to its charging and discharging principle. When charging the battery, the lithium ion is generated on the positive electrode of the battery, and the generated lithium ion moves through the electrolyte to the negative electrode. As the anode carbon is layered structure, it has many micropores, and the lithium ion which reaches the negative electrode is embedded into the micropores of the carbon layer. The more the embedded lithium ion, the higher the charging capacity. Similarly, when the battery is discharged (i.e., we use the battery), the lithium ions embedded in the negative carbon layer are removed and moved back to the positive electrode. The more lithium ion goes back to the positive electrode, the higher the discharge capacity. What we usually refer to as battery capacity is the discharge capacity. It is easy to see that in the process of charging and discharging of Li ion battery, the lithium ion is in the state of movement from positive to negative to positive. If we compare the lithium ion battery to a rocking chair, the two ends of the rocking chair are the poles of the battery, and the lithium ion is like a good sportsman, running back and forth at both ends of the rocking chair. So the experts gave the lithium-ion battery a lovely name rocking chair battery. Lithium ion battery is a lithium battery appeared a few years ago the alternative products, it can be used to the anode of lithium ion absorbing carbon electrode, discharge, lithium lithium ion battery anode into, out of, to the cathode of lithium ion battery. The lithium ion moves between the anode and cathode, and the electrode itself does not change. This is essentially the difference between a lithium-ion battery and a metal lithium battery. The anode of lithium ion battery as cathode graphite crystal, lithium hydroxide is usually two. When charged, the lithium atoms in the cathode are ionized into lithium ions and e
