Chemical stability at higher temperatures, electrolyte decomposition should also not occur when the negative potential is higher than the lowest unoccuated molecular orbital of an electrolyte produced by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, or the positive potential is lower than the highest occupied molecular orbital of the electrolyte. If the positive and negative electrode potentials are outside the electrochemical window of the electrolyte, kinetic stability can be achieved by forming an SEI film on the electrode surface, but at the cost of capacity loss.
During fast charging, the concentration of lithium ions on the surface of the SEI film will increase, and the volume change of the electrode will also destroy the SEI film. Lithium evolution may occur before the repair of the gap in the SEI film. Lithium deposition can lead to the growth of lithium dendrites, penetrate the diaphragm through the electrolyte, and cause internal short circuit of the battery, leading to safety risks. This safety issue is addressed in power batteries for applications using PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal as a negative electrode.
The development trend of electrolytes for removing iron in the future will be from the current organic liquid electrolyte to solid electrolyte gradually transition, during which there will be a variety of other systems of electrolytes. The research and development of electrolytes requires comprehensive consideration of their electrochemical properties, thermodynamic properties, kinetic properties, etc.
