Analysis of new battery technology after lithium-ion rechargeable battery

The new battery after the rechargeable lithium battery: 7 times the energy density Compared with the existing lithium ion rechargeable battery, the energy density of the component is increased by about 7 times, and the cost is reduced to 1/40. This is the policy on the battery function of electric vehicles proposed by the Ministry of Economy and Industry. This is the 2030 policy value proposed in the report 'Recommendations for New Generation Car Batteries' published by the Ministry of Economy and Industry at a seminar in August 2006. Three years after the report was published, it is still regarded as a roadmap for battery development. Seven times the energy density is very necessary. According to the EV launched in 2009, the IMiEV of Mitsubishi Sedan is 160km, and the Subaru plug-in Stella of Fuji Heavy Industries has a continuous driving range of 80km. In 2009, when the electric car was just launched, the scene in the city was meaningful. But in the future, all gasoline vehicles will be replaced, and such a function is obviously lacking in strength. The energy density of this battery is 7 times the current energy density, at least not 7 times that of lithium-ion rechargeable batteries. Using only the triangular combination of negative electrode LiC6 (intercalated lithium graphite), LiCoO2 (lithium cobalt oxide) or LiMn2O4 (lithium manganese oxide), electrolyte (organic solvent), no matter how improved, it will not get rid of the constraints of the data itself. The above three types of data have theoretical limitations, so it is useless to achieve a leap forward. In order to break this barrier, people are researching and developing batteries that exceed the limits of lithium-ion rechargeable batteries. The purpose is to break the triangle combination in a corner and make the function go forward greatly. For example, lithium-ion rechargeable batteries using ionic liquids, all-solid-state lithium-ion rechargeable batteries and lithium-air batteries. At present, research institutes such as Osaka Prefecture University, Kansai University, Industrial Technology Induction Research Institute, and Power Center Research Institute are developing such batteries. The company is not yet an important participant. However, there are also many car manufacturers interested in cooperating with these seminars. At the same time, Toyota announced that it has begun joint discussions with Osaka Prefectural University. In today's lithium-ion rechargeable batteries, the root of the problem lies in the use of organic solvents in the electrolyte. Organic solvents are easy to catch fire or leak. Although lithium itself is risky, organic solvents can cause trouble. Otherwise, the presence of solvent will dilute the electrolyte. The work is carried out by ions, so the remaining solvent will form an obstacle to the work, thereby dragging down the functional indicators, making it difficult for the energy density to reach 7 times.
