EV Vision reports that Toyota's solid-state battery technology has been receiving great attention. This high-efficiency battery technology, which can be fully charged in 10 minutes, is expected to be launched with the mass-produced pure electric vehicles of Toyota's e-TNGA platform next year. This will not only change

Electric vehicles will also change the entire industry structure.

Solid-state batteries are different from current liquid lithium battery technology and have the advantages of small size, non-flammability, fast charging speed, and high energy density.

Toyota cooperated with solid-state battery startup Ilika in 2008. In early 2019, it cooperated with Panasonic to accelerate its layout and strive to achieve mass production of solid-state batteries as soon as possible.

Toyota has a lot of battery technology in its hands, and has applied for more than 1,000 patents, and is vigorously expanding its electric vehicle territory.

Toyota had hoped to debut its solid-state battery technology during the Tokyo Olympics.

"Nikkei" reports that Toyota's solid-state battery technology may debut with the mass-produced electric vehicles launched in the European market next year. This electric SUV named BZ3 is in the same class as the RAV4, with a maximum endurance of about 500km, and uses e-

Built on the TNGA platform.

BZ3 electric vehicle preview Toyota plans to release a trial vehicle equipped with an all-solid-state battery in 2021 and begin performance testing. The all-solid-state battery vehicle currently developed has a driving range of 500 kilometers, which is more than twice that of a vehicle equipped with a lithium-ion battery under the same conditions.

In line with the research and development trends of car companies, Japanese raw material manufacturers are also accelerating. Mitsui Metals and Idemitsu Kosan plan to start producing solid electrolytes in 2021.

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. In the future, the cost needs to be less than 100 US dollars/kWh to compete with fuel vehicles. Toyota will promote the development of solid-state battery business through Taixing, a joint venture established with Panasonic.

Japanese Prime Minister Yoshihide Suga stated on December 4 that in order to achieve the goal of achieving carbon neutrality by 2050, he plans to establish a 2 trillion yen fund to provide assistance to companies engaged in the research and development of carbon reduction-related technologies such as batteries and hydrogen energy.

Yoshihide Suga pointed out that an unprecedented 2 trillion yen fund will be established to provide assistance to companies that challenge innovative technologies over the next 10 years.

Since solid-state batteries use lithium, which has limited global reserves, the government will help acquire the material.

Japanese private research institute Yano Economic Research Institute estimates that the global next-generation battery market (including all-solid-state lithium-ion batteries, metal-air batteries, etc.) will significantly expand to 1.494 billion yen in 2030, a sharp increase from 2018.

About 22 times, among which the high-capacity all-solid-state lithium-ion battery market is the largest, estimated to reach 568.7 billion yen in 2030, accounting for nearly 40% of the overall market.

Japanese market research agency Fuji Keizai predicts that the global all-solid-state lithium battery (all-solid-state battery; including sulfide series, oxide series, polymer series, etc.) market size is expected to expand to 2 trillion in 2035

677.2 billion yen, which will surge 1,114 times compared with 2.4 billion yen in 2018.

As the 30th year of lithium-ion battery industrialization, battery technology in 2020 will enter a new cycle of change.

At present, the safety issues of lithium batteries have not been resolved, so solid-state batteries have become the direction of the next generation of lithium battery technology.

At this stage, there are very few mass-produced solid-state battery products, and the industrialization process is still in its early stages. There are three main camps: Europe, the United States, Japan, South Korea, and China.

European and American car companies pay more attention to solid-state battery start-ups.

Volkswagen, Renault and other car companies have acquired technology reserves through acquisitions and investments in start-ups including Solid Power, Solid Energy Systems, Ionic Materials, Quantum Scape, etc.

Dyson, which has given up building 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 a smartphone using solid-state battery technology will be released in the next one to two years.

LG Chem is also conducting research and development of solid-state battery technology and has made good progress, reaching a level similar to Samsung.

Although China started late, more and more scientific research institutes and battery companies have participated, including research institutions such as the Institute of Chemistry of the Chinese Academy of Sciences, Ningbo Institute of Materials of the Chinese Academy of Sciences, Ganfeng Lithium Industry, CATL, BYD, etc.
