Different from the current liquid lithium battery technology, solid-state battery has the advantages of small volume, non-flammability, fast charging speed and high energy density. In 2008, Toyota cooperated with Ilica, a solid-state battery company, and cooperated with Panasonic at the beginning of 20 19 to speed up the layout and strive to realize mass production of solid-state batteries as soon as possible. Toyota holds quite a lot of battery technology, and has applied for more than 1000 patents, vigorously expanding the territory of electric vehicles.
Toyota hopes to demonstrate its solid-state battery technology during the Tokyo Olympic Games. "Nikkei News" reported that Toyota's solid-state battery technology may be launched together with mass-produced electric vehicles listed in the European market next year. This electric SUV named BZ3 is the same as RAV4, with a maximum battery life of about 500km, and is built on the e-TNGA platform.

Toyota plans to unveil a prototype with all-solid-state batteries in 20021year and start performance testing. At present, the all-solid-state battery car has a cruising range of 500 kilometers, which is more than twice that of the car equipped with lithium-ion battery under the same conditions. In line with the research and development trend of automobile enterprises, Japanese raw material manufacturers are also accelerating their pace. Mitsui Metal and Chu Guang plan to start producing solid electrolyte in 20021year.
Regarding the future planning of solid-state batteries, Toyota insiders have previously revealed that they hope to mass-produce solid-state batteries by 2025. The biggest problem at present is to solve the cost problem. The future cost needs to be less than 100 USD/kWh to compete with fuel vehicles. Toyota will promote the development of solid-state battery business through Taixing, a joint venture with Panasonic.
On February 4th, 65438, Japanese Prime Minister Suga Yoshihide said that in order to achieve the goal of carbon neutrality in 2050, he planned to set up a fund with a scale of 2 trillion yen to provide assistance to enterprises engaged in research and development of carbon reduction related technologies such as batteries and hydrogen energy. Suga Yoshihide pointed out that an unprecedented 2 trillion yen fund will be set up to provide assistance to enterprises that continue to challenge innovative technologies in the next 10 year. Since solid-state batteries use lithium, which is limited in the world, the government will help to obtain this material.
Yano Economic Research Institute, a Japanese private research institution, predicts the global market scale of the next generation batteries (including all-solid-state lithium-ion batteries and metal-air batteries, etc.) in 2030. ) will greatly expand to 6,543.8+0,494.0 billion yen, an increase of about 22 times compared with 2065,438+08. Among them, the market for high-capacity all-solid-state lithium-ion batteries is the largest, and it is expected to reach 568.7 billion yen in 2030, accounting for the whole.
Fuji economy (Fuji? Keizai) predicts that in 2035, the global all-solid-state lithium battery (all-solid-state battery; Include sulfides, oxides, polymers, and the like. ) will be expanded to 2 trillion 677.2 billion yen, an increase of114 times compared with 2.4 billion yen in 2065438.
As the 30th year of lithium-ion battery industrialization, battery technology will enter a new revolutionary cycle in 2020. At present, the safety problem of lithium battery has not been solved, so solid-state battery has become the direction of the next generation lithium battery technology. At present, there are few mass-produced products of solid-state batteries, and the industrialization process is still in the early stage, mainly including Europe, America, Japan, South Korea and China.
European and American car companies pay more attention to solid-state battery start-ups. Startups acquired and invested by Volkswagen, Renault and other car companies include Solid? Power and solid energy? Systems, ions? Materials, quantum? Scape and others gain technical reserves. Dyson, who gave up making cars, is also focusing on the research and development of solid-state battery technology.
In South Korea, Samsung SDI is developing a new solid-state battery. It is expected that smart phones using solid-state battery technology will come out in the next one to two years. LG Chem is also developing solid-state battery technology, and has made good progress, reaching a level similar to that of Samsung.
Although China started late, more and more research institutes and battery companies are involved, including Institute of Chemistry of Chinese Academy of Sciences, Ningbo Institute of Materials of Chinese Academy of Sciences, Ganfeng Lithium Industry, Contemporary Anpu Technology Co., Ltd. and BYD. ?
