The advantages and disadvantages of all solid-state lithium-ion batteries and their classification

1) The safety is good, the electrolyte is non-corrosive, non-flammable, and there is no leakage problem; 2) The high temperature stability is good, and it can work between 60℃-120℃; 3) Higher energy density is expected. The solid electrolyte has good mechanical properties and effectively inhibits the short-circuit problem caused by the diameter growth of lithium element. It makes it possible to choose electrode materials with higher theoretical capacity, such as lithium element as the negative electrode; the voltage window of the solid electrolyte is wider, and higher potentials can be used. The material used as the positive electrode does not hesitate to worry about electrolyte decomposition; 4) The solid electrolyte supports the thin-film design of the cell, which can be as small as a few nanometers, which broadens the application range of lithium-ion batteries and makes it possible for the battery to have its own flexibility. 5) The positive and negative electrodes can be made of materials with large resistance and large volume changes during charging and discharging. Thin film positive and negative materials, as long as the film-forming performance is good, even if the material resistance is too large, as long as the material is thin enough, it will still not It has a significant impact on battery characteristics. Disadvantages 1) When the temperature is low, the internal resistance is relatively large; 2) The material conductivity is not high, and it is difficult to increase the power density; 3) It is difficult to manufacture large-capacity monomers; 4) The positive and negative film forming technology in large-scale manufacturing is still In concentrated firepower research. The classification of all-solid-state lithium-ion batteries is accompanied by the rise of all-solid-state lithium-ion batteries, and various all-solid-state or solid-state concept lithium-ion batteries have appeared one after another, and there is a status quo of confusion. Solid-state lithium-ion batteries: Some researchers turn batteries that contain a solid electrolyte with a higher mass or volume ratio and a small amount of liquid electrolyte into a solid-state battery, but this is actually not an all-solid-state battery. All-solid-state lithium-ion battery: The battery core is composed of solid electrodes and solid electrolyte materials. The battery core does not contain any mass and volume fraction of liquid electrolyte within the operating temperature range.
