Can solid-state batteries replace the status of lithium batteries?

The so-called solid-state battery is the use of solid materials as electrolyte. Compared with traditional lithium batteries, all-solid-state batteries have distinct advantages. Under the same energy, solid-state electrolytes are used to replace electrolytes and thin films. All-solid-state batteries are thinner and more bulky. smaller. And because the solid electrolyte replaces the potentially explosive organic electrolyte in traditional lithium batteries, this solves the two major problems of high energy density and high safety features, thereby eliminating the anxiety of electric car users, and even longing to complete fast charging. Solid-state batteries are regarded as the development direction of the new power car battery technology road because of their high safety and advanced energy density. At present, many countries around the world are committed to the development of solid-state batteries. At present, in addition to Ningbo Institute of Chinese Academy of Sciences, Qingdao Institute of Power Engineering of Chinese Academy of Sciences, Ningde Times, AVIC Lithium Battery BYD and many other research institutions and power lithium-ion battery companies are also engaged in the development of solid-state batteries. In comparison, lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use a non-aqueous electrolyte solution. Lithium batteries are widely used in mobile phones, notebook computers, digital cameras, electric vehicles, power tools, new-powered cars and other occupations. Its advantages are relatively high energy and high storage energy density, which is 6-7 times that of lead-acid batteries. It has a long service life when used together, and the service life can reach more than 6 years under normal use. Light weight, the weight of the same volume is about 1/6~1/5 of the lead-acid battery, high and low temperature adaptability can be used in the environment of minus 20 degrees to 60 degrees, green and environmentally friendly. However, the lithium battery is not a perfect condition, because its safety function is relatively poor in the process of use, and there is a risk of explosion. At the same time, the lithium battery needs to use the maintenance circuit to guard against the battery being overcharged or overdischarged. Solid-state batteries may be one of the development directions of battery technology in the future, but as far as current technology is concerned, it is not the best. The first is its price. The cost of liquid lithium batteries is about US$200 to US$300 per kWh. The cost of the solid-state battery is 15,000 US dollars. Which road to choose in the end is still a need to see which road is developed faster and more grounded. The so-called grounding gas can be both in terms of commercialization planning and cost. To reach a perfect balance point, the first use of data must not be high-cost and scarce, and secondly, it must be possible to complete large-scale applications in various occupations and fields. From the theoretical perspective, solid-state batteries are not a new concept, but as far as the current situation is concerned, its development is not as fast as imagined. However, from the perspective of the improvement of application functions, solid-state batteries are still worth the wait.
