What are the characteristics of lithium battery fast charging circuit

Lithium battery designers are well aware that rapid charging will seriously affect the life of lithium batteries. This is often because when Li+ is quickly embedded in the graphite lattice of the negative electrode, severe mechanical stress will occur in the graphite material, which will cause the graphite negative electrode material to appear degraded. The problem of layer and particle cracking, in addition, too fast charging speed or low battery temperature during charging may also cause metal Li to precipitate on the surface of the negative electrode, which will lead to the loss of reversible capacity of the lithium battery and the decline of cycle life. With the upgrading of battery technology, lithium batteries are gradually replacing lead-acid batteries as energy storage carriers in the new era, but the inherent charging characteristics of lithium batteries restrict their large-scale and in-depth use in various industries. The load and type of positive electrode material will also affect the fast charging characteristics of the battery, which should also be considered when designing the battery. To charge the lithium battery, the charging current and charging voltage must be controlled in chronological order, and excessive charging is not allowed, otherwise the battery will be easily damaged. The use of lithium batteries has been very extensive. Mastering the fast charging technology of lithium batteries promotes its practical use and has broad commercial prospects.
