This technology will usher in a new era of electric vehicles, because solid-state batteries are more compact, faster, safer and have higher energy density than the traditional lithium-ion batteries widely used at present. They use solid electrolytes instead of liquid or gel polymer electrolytes in lithium ion cells. This means that they need less physical space to generate the same energy, and they are not easy to catch fire when damaged.
It is estimated that the cruising range of the solid state vehicle can reach 65,438+0,000 kilometers (6,265,438+0 miles) and the charging time is 65,438+00 minutes. Solid-state batteries have a low degree of aging over time, and Toyota's goal is to retain 90% battery performance within 30 years of service life. Toyota is in the leading position in the number of patents for solid-state batteries, with more than 65,438+0,000 patents related to this technology.
However, there are still difficulties in the production of solid-state batteries. They need extremely dry conditions in the production process, and the required lithium is a scarce resource. In order to help speed up the development of this technology, the Nikkei News reported that the Japanese government is considering using part of the newly established 2 trillion yen (US$ 65.438+09.2 billion) decarbonization fund to build solid-state battery production infrastructure in China. Mitsui products, gasoline company Idemitsu? Industrial enterprises such as Kosan and Sumitomo Chemical are preparing to produce solid electrolytes.
Volkswagen said that it will produce its own solid-state batteries by 2025, and Nissan expects to produce solid-state battery prototypes by 2028.
Toyota is jointly developing this battery with Panasonic, the leader of battery technology, and plans to disclose some information during the Tokyo Olympic Games this summer. Although the Olympic Games was cancelled due to the coronavirus pneumonia-19 epidemic, Toyota did not disclose when the battery prototype made its first public appearance. Now it seems that this will be some time on 202 1.
