All solid state what are the advantages of lithium secondary battery?

Source: 2020 - 03 - Then click traffic: 30 solid-state lithium secondary battery may have a solid-state lithium batteries relative to the liquid lithium ion battery advantages include: ( 1) Safety performance is high due to the electrolyte containing flammable organic solvents, internal short circuit temperature soaring attack is easy to cause burning, explosion, even short-circuit security equipment are in need of resistance temperature rise and equipment structure, this will increase the capital, but still can't completely solve the problem of security. Claims to be the best in the world the tesla BMS, the Model S serious fire broke out in China alone this year. Many inorganic solid electrolyte data is nonflammable, no corrosion, no evaporation, no leakage problem, and is expected to overcome the phenomenon of lithium dendrite, so according to the inorganic solid electrolyte solid-state lithium secondary battery is expected to have high security features. Polymer solid electrolyte still exists certain risk of burning, but compared to liquid electrolyte battery containing flammable solvents, its security has greatly improved. ( 2) At present, the higher energy density of lithium-ion batteries used in the shop the energy density of up to 300 wh/kg. For all solid state lithium battery, if the use of lithium metal in cathode, the energy density is expected to reach 300 - 400 wh/kg or more. The requirement shows that, due to the density of the solid electrolyte is higher than the density of liquid electrolyte, so for the same positive and negative data system, liquid electrolyte of lithium battery energy density is significantly higher than all the solid the energy density of lithium-ion batteries. The whole solid lithium secondary battery energy density is high, because the cathode can choose lithium metal data. ( 3) Long cycle life of solid electrolyte can avoid in the process of charging and discharging, liquid electrolyte to the formation and growth of solid electrolyte interface membrane, lithium dendrite through the problems of membrane, can greatly improve the metal lithium battery cycle and service life. ( 4) Wide working temperature range solid-state lithium battery if all use inorganic solid electrolyte, the highest working temperature is expected to increase to 300 ℃ is even higher, at present the low temperature function of high-capacity solid-state lithium batteries. Specific work temperature range of the battery mainly with high and low temperature properties of electrolyte and interface resistance. ( 5) Wide electrochemical window, all solid state lithium battery of the electrochemical stability window wide and up to 5 v, suitable for high voltage electrode data, is conducive to further improve the energy density. Now the mainstream sanlian battery voltage in 4. 2 v to 4. Between 5 v. It possesses the advantages of flexibility solid-state lithium battery can be made into flexible thin-film batteries and battery, can be used for future intelligent wearable and implantable medical devices. Associated with flexible liquid electrolyte of lithium battery, the packing is more simple, more secure.
