Which is the best lithium electrolyte?

The best lithium electrolyte charge and discharge current density impact on the performance of lithium electrodes and capacity decay mechanism The surface of the lithium electrode is always covered with a layer of the original film composed of Li20-LiOH, when it is immersed in the DW-based electrolyte, they Still has a certain degree of stability. When it discharges at a lower rate, the original film does not change quickly, but maintains partial stability. Subsequently, because only part of the lithium surface reacts with the components of the electrolyte, while the other part still maintains the original surface compound, the surface of the lithium electrode becomes very uneven. Therefore, under the above circumstances, the surface of the lithium electrode is uneven and mosaic-like, which leads to unevenness in the lithium deposition process, and dendrites appear, and the rate of lithium corrosion increases, so that the performance of the entire battery is In terms of cycle life, it becomes very poor. When these lithium battery systems are discharged at a higher rate, the lithium that overturns the original surface film will be quickly exhausted, so these surfaces will become very unstable and will soon be affected by the SEI film composed of solvent reduction products. Instead, the lithium deposition process may be very average, and the lithium deposition morphology is relatively smooth. Although in the DN-based electrolyte, the passivation of the lithium electrode surface is very effective, it is almost impossible to obtain a completely dense and uniform SEI film with no defects at all. Therefore, in the process of charging and discharging, there are some small-scale reactions between the lithium electrode and the electrolyte. The continuous reaction between the electrolyte and the lithium during the cycle process consumes the limited lithium and electrolyte in the battery, which limits the cycle life of the battery. For the most important reason, it eventually led to the destruction of the battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
