| As a research hotspot , amorphous solids electrolyte for lithium-ion secondary batteries has become one of the most active fields in condensed matter physics and an advanced part in material science. Non-crystal electrolyte for lithium-ion secondary batteries involves a great deal of physical problems . Researching and discovering the knowledge with regard to physics can benefit our exploitation of lithium battery materials.As far as amorphous solids is concerned ,it has no strict periodic structure as crystal. Because the bond interactions which makes the solid combine determines the short-distance order radically ,it is the same both in crystal and non-crystal, the short -distance order is also determined in essence. The distinction lies in that crystal is long -distance order and non-crystal is long -distance disorder. Therefore , amorphous solids demonstrates different characters from crystal.We can apply the crystal growth theory to the formation of the amorphous solids if we regard the amorphous solids formation as a process with small nucleating rate or crystal nucleus growth rate. From the point view of crystal dynamics ,we discuss the ability of material forming non-crystal and introduce the method that can figure out the substance criticalcooling rate Q* by using T-T-T figure(Time-temperature-transformation curve ,also called 3-TFigure) All of these above-mentioned are of great significance for us to exploit new amorphous solids materials ,probe into the new approach to make non-crystal materials and understand the stability of materials.Free volume model is one of the most widely used models in amorphous transformation ,Hquid amorphous transformation is the macroscopic exhibition of molecular free volume microscopic changes. The increase of public entropy is a basic character of amorphous liquid transformation.We have figured out the theoretical conductance rate of amorphous electrolyte Li6Si2O2S5 by citing the Nernst-Einstein equation .It's 10-3S/cm...
