Will solid-state batteries take over the position of lithium batteries? With the development of battery technology, there are different types of batteries, solid-state batteries can increase the charging speed of the battery, while the range is higher than lithium batteries, solid-state batteries because of its high safety, energy density and other advantages are seen as the development direction of the new energy vehicle battery technology route.
Will solid-state batteries take over the position of lithium batteries?
The so-called solid-state battery, as the name implies, uses solid materials as the electrolyte. Compared with traditional lithium batteries, all-solid-state batteries have obvious advantages, replacing electrolyte and film with solid electrolyte at the same energy, and all-solid-state batteries are thinner and smaller.
The working principle of solid-state battery is the same as that of traditional lithium battery. The difference of solid-state lithium batteries is that they use solid substances (e.g., polymers and inorganic materials, etc.) as electrolytes instead of the liquid electrolytes used in traditional lithium batteries. It is called solid-state battery because of the use of solid-state electrolyte.
Since the solid-state electrolyte replaces the organic electrolyte in the traditional lithium-ion battery, which may ignite and explode, this solves the two major problems of high energy density and high safety performance, thus eliminating the "range anxiety" of electric vehicle users, who even desire to achieve fast charging.
Solid-state lithium batteries do have a lot of advantages, because the solid electrolyte has a non-flammable, non-corrosive, non-volatile, non-leakage nature, will not make the vehicle spontaneous combustion events, greatly enhancing the safety, is indeed an ideal battery material for electric vehicles.
From the analysis of the structure of solid state battery and lithium battery, solid state battery is simply a kind of battery using solid electrode and solid electrolyte. In terms of solid electrolyte, it is non-flammable, non-corrosive, non-volatile, non-leakage, and also overcomes the lithium dendrite phenomenon, making it safer. Although the advantages of solid-state batteries are obvious from the top of the structure, there is still a way to go to replace lithium batteries.
Solid-state batteries may be one of the future directions of lithium battery technology, but the current technology is not the best, first of all, it is a price, the cost of liquid lithium batteries is about $ 200-300 per kilowatt hour, the cost of solid-state batteries to 15,000 U.S. dollars.
Lithium battery in the material structure, metal material electrodes are more mature, with a complete industrial chain, from the cost of the above to lower than the solid-state battery, on the whole, if the solid-state battery technology can overcome certain obstacles, and low cost, then replace the lithium battery is only a matter of time.
Lithium batteries are welcomed by the new energy vehicle industry and have made great strides because of their high energy density, low self-discharge rate, high cycle efficiency and long cycle life. Lithium battery is not a perfect state, because it is relatively poor safety performance in the process of use, there is a risk of explosion, while lithium batteries are required to use the protection line to prevent the battery is overcharged or overdischarged.
In summary: solid-state batteries or replace lithium batteries to become mainstream, the technology has made a lot of progress but still not industrialized, in general, the research on solid-state batteries, or more academic, in the industrialization, because some key technologies involved in the core technology of each enterprise and can not be obtained, resulting in engineering-based application of technology or need to be further explored.
