Thus, compared with liquid batteries, the advantages of solid-state batteries can be said to be considerable; However, it is not without its shortcomings. One of the biggest problems in mass production application of solid-state batteries is cost. Although the cost of liquid battery is not low, it is also a drop in the bucket compared with solid-state battery. It is understood that the cost of mobile phone solid-state batteries is around 60,000 yuan. It is conceivable that if it is an electric car, the cost will be high. However, this is only the current form. Perhaps in the future, solid-state batteries can also be completely "civilian", but this requires powerful enterprises in the battery field to invest in early research and development.
We know that Japan has always been in a leading position in the field of batteries, but although pure electric vehicles are developing in full swing in various countries, Japan does not seem to be so diligent. The reason is not that Japanese car companies do not have the corresponding technical strength, but that they are not interested in batteries with many problems. So they are more willing to focus on hydrogen fuel cells with higher technology. However, after solid-state batteries showed many advantages over liquid batteries, many Japanese car companies put their energy into the research and development of solid-state batteries. The reason is naturally that Japanese car companies have seen the development prospects of solid-state batteries.
As early as 20 12, Toyota officially announced that it had achieved certain research and development results in the field of solid-state batteries. Then there are big car companies in the automobile industry, such as BMW, Honda, Nissan, Volkswagen and Hyundai. China's Great Wall and BYD have both announced their solid-state battery layouts in the past two years. According to incomplete statistics, there are more than 100 manufacturing enterprises and scientific research institutes in universities around the world devoted to the research and development of solid-state batteries. But today, Toyota or Japanese car companies still maintain a leading position in solid-state batteries. Especially in terms of patents, Toyota has obtained 26 patents so far, ranking first in the single institution of solid-state battery research and development.
Not only that, Toyota revealed before the 20 19 Tokyo Motor Show that it will launch a new energy vehicle equipped with solid-state batteries during the 2020 Tokyo Olympic Games, but the specific mass production time of this car may have to wait until 2025. This may indicate that Toyota has made a breakthrough in the research and development of solid-state batteries, and even will soon come up with finished products, which can be called preemptive strike. In addition, in 20 18, the Japanese government, battery manufacturers, Toyota, Honda and Nissan established cooperative relations and announced that they would jointly develop solid electrolyte lithium-ion batteries, that is, solid-state batteries. Perhaps the greatest significance of this cooperation lies in sharing the R&D cost and speeding up the mass production of solid-state batteries, thus occupying a more favorable position in the world.
