What is the difference between solid-state batteries and lithium-ion batteries?

The advantages of solid-state batteries compared with traditional lithium-ion batteries are obvious. The first is volume. Since electrolyte and barriers are not needed, solid electrolytes are used instead, and the thickness of solid-state batteries will be smaller under the energy density of communication. Secondly, in terms of weight, after using a solid electrolyte, the graphite negative electrode can be replaced with metal lithium to reduce the amount of negative electrode material and significantly reduce the weight of the entire battery. At the same time, higher security and better fast charging capabilities are also its advantages over current lithium-ion batteries. When integrated into electric vehicles, solid-state batteries also have the advantages of compact layout, adjustable limits, and large design flexibility, which are conducive to vehicle integration. Take the e-Golf, the first electric bus for buses, for example. Its current cruising range is 300 kilometers. If the solid-state battery technology is recovered, its cruising range can be increased to 750 kilometers. But at present, due to cost and technical factors, it is difficult for solid-state batteries to be commercialized in a short period of time. At present, the world's mainstream automakers have regarded electrification as the hinterland for future growth. Relatively speaking, buses are not advanced in the electrification scale, but the influence of electrification strategies is not significant. According to the RoadmapE electrification strategy requirements issued by buses in September 2017, buses will realize electrification of the entire model lineup by 2030 at the latest. This means that there will be at least one electric version of each of the more than 300 models under the umbrella of the public organization. To achieve this plan, buses will have a battery capacity of 150 gigawatt hours higher by 2025, which is equivalent to the annual output of at least four super battery factories. The army has not moved the grain and grass first. In order to make the battery production meet the matching requirements of RoadmapE, in September 2017, the public group Mianzi launched a 50 billion euro battery bidding globally. As of now, the public organization has signed a purchase quota of 20 billion euros. A Chinese battery assisting companion is the Ningde era. In addition, Samsung SDI and Panasonic are also important battery suppliers for public organizations. These battery suppliers also have tactics to help BMW and Toyota, which means that buses follow in the footsteps of BMW and Toyota in battery supply. It is conceivable that the public wants to break through on this scale. In terms of power lithium batteries, the public is better off opening a new path instead of following in the footsteps of others. In order to break free from the dependence of Asian battery manufacturers, while gaining leading skills in battery scale.
