What are the characteristics of all solid-state thin-film lithium batteries?

Features of all-solid-state thin-film lithium batteries All-solid-state thin-film lithium batteries have extremely high safety. Its solid electrolyte is non-flammable, non-corrosive, non-volatile, and does not leak. It also overcomes the phenomenon of lithium dendrites. Cars equipped with all-solid-state lithium batteries The probability of spontaneous combustion will be greatly reduced. The all-solid-state lithium battery adopts a new solid electrolyte to replace the current organic electrolyte and diaphragm. It has high safety and high volume energy density. At the same time, it has wide compatibility with different new high specific energy electrode systems, which can further improve the mass energy density, which is expected Become the ultimate solution for next-generation power lithium-ion batteries. (1) High safety performance: Inorganic solid electrolyte materials are non-flammable, non-corrosive, non-volatile, and have no leakage problems. Compared with liquid electrolytes containing flammable solvents, polymer solid electrolytes have greatly improved battery safety. (2) High energy density: Metal lithium can be used for the negative electrode of all solid-state lithium batteries, and the energy density of the battery is expected to reach 300-400Wh/kg or even higher; its electrochemical stability window can reach more than 5V, which can be matched with high-voltage electrode materials to further improve Mass energy density. (3) Long cycle life: It is expected to prevent the problem of continuous formation and growth of SEI film and lithium dendrites piercing the diaphragm during the charging and discharging process of liquid electrolyte, and greatly improve the cycle performance and service life of metal lithium batteries. (4) Wide operating temperature range: All solid-state lithium batteries have excellent acupuncture and high temperature stability. If all inorganic solid electrolytes are used, the maximum operating temperature is expected to reach 300°C, thereby preventing the positive and negative materials from reacting with the electrolyte at high temperatures. The resulting thermal runaway. (5) Improved processing efficiency: No need to encapsulate liquid, support serial stacking arrangement and bipolar mechanism, which can reduce the ineffective space in the battery pack and improve the processing efficiency.
