Reinventing the future: Toyota leads the solid-state battery revolution
Recently, the Financial Times revealed exciting news that Toyota has made a major breakthrough in solid-state battery technology, which is expected to completely change the electric vehicle industry landscape. With a breakthrough in solid-state battery technology, Toyota has shown ambitions to halve the size, cost and weight of electric vehicle batteries.
Behind this breakthrough is the unremitting efforts of Toyota's top battery expert Keiji Kaita. According to a report on July 4, he said that simplifying the production process of battery materials will significantly reduce the cost of next-generation technology, aiming to solve the problem of batteries that are too large, too heavy and too expensive. That goal may seem far away, but Keiji Kaita is optimistic about the future, saying: "Our goal is to halve all of these factors. ”
Solid-state battery technology has not only had a huge impact within Toyota, but has also attracted widespread attention around the world. Professor Ma Cheng of the University of Science and Technology of China has also made breakthroughs in the field of solid electrolytes. The comprehensive performance of this new solid electrolyte is close to the most advanced sulfide and chloride solid electrolyte, but the cost is less than 4% of the latter, which provides the possibility for industrial application.
This good news quickly attracted the attention of the market, and the solid-state battery sector was shaken up, and major companies joined the ranks. Jinlongyu, China Self Technology, Zhuhai Guanyu, Shanghai Washba, Oriental Zirconium and other enterprises have followed the fluctuations of the financial market and achieved rapid stock price rise.
Towards the pinnacle of technology: Toyota's ambition for solid-state batteries
Toyota's solid-state battery breakthrough has sparked widespread speculation and discussion in the industry. The world's second-largest automaker has a plan to launch electric vehicles with advanced solid-state batteries by 2025, according to CaiLian News. Compared with traditional liquid batteries, solid-state batteries have greater advantages, which is also the direction that Toyota actively pursues.
Keiji Kaida, president of Toyota's carbon neutral R&D center, said: "Whether it is a liquid battery or a solid-state battery, our goal is to completely change the current situation of batteries that are too large, too heavy, and too expensive. He revealed that the company has made breakthroughs in improving battery durability and believes that in the future, it can create solid-state batteries with a range of 1200 kilometers, and the charging time is even as little as 10 minutes.
Industry experts also spoke highly of the significance of this breakthrough. David Bailey, a professor of business economics at the University of Birmingham, believes that if Toyota's claims are true, then this could be a milestone moment for electric vehicles. "If this is a real breakthrough, then it could be a game-change, or even the holy grail of the electric vehicle industry," he noted. ”
Challenges and opportunities: the future of solid-state batteries
Toyota's efforts and breakthroughs have triggered extensive discussions on the future of solid-state battery technology around the world. Toyota reportedly plans to start producing solid-state batteries for electric vehicles in 2027 to bring this innovative product to market.
Not only that, Toyota's investment in the field of solid-state batteries is also huge. According to the 2021 announcement, Toyota plans to invest 1.5 trillion yen in the development of power batteries and their battery supply chain by 2030 to maintain its leading position in key automotive technology fields.
In addition, Toyota is also carrying out a comprehensive strategic layout in the field of batteries for pure electric vehicles. According to the news in June, Toyota will launch a "all-round" strategy that meets all needs to meet the growing demand for electric vehicles. Toyota's strategy is attracting attention from Japan's Ministry of Economy, Trade and Industry, which will subsidize Toyota's battery investments to boost the electric vehicle industry.
The road ahead: the possibilities of solid-state batteries
With the breakthroughs made by Toyota and others in the field of solid-state batteries, Chinese scientists have also taken an important step in this field. Professor Ma Cheng of the University of Science and Technology of China has developed a new solid electrolyte, which not only has comprehensive performance close to the most advanced solid electrolyte, but also has only the latter
A quarter of which is very suitable for industrial applications. This innovative achievement was published in the internationally renowned academic journal Nature Communications, marking an important breakthrough in the field of solid-state batteries in China.
This new solid electrolyte adopts lithium zirconium oxychloride, which not only has a strong cost advantage, but also is comparable to the most advanced sulfide and chloride solid electrolytes in terms of comprehensive performance. The experimental results show that the all-solid-state lithium battery composed of lithium zirconium oxychloride and high-nickel ternary cathode can still cycle stably for more than 2,000 cycles at room temperature under the condition of 12-minute fast charging.
This technological breakthrough caused a huge sensation in the industry. Ouyang Minggao, a professor at Tsinghua University, said that although solid-state battery technology faces challenges, it is still worth pursuing. He pointed out that the pace of commercialization of technology is accelerating, and the number of papers on solid-state battery technology in the world's top journals is increasing exponentially, which shows that its commercialization prospects are becoming increasingly clear.
Toyota, a leader in solid-state battery technology, has begun to put this innovative technology into practical use. It is understood that Toyota plans to achieve small-scale mass production from 2025, first applying solid-state batteries to hybrid models. By 2030, Toyota aims to achieve sustained and stable mass production of all-solid-state batteries, laying a solid foundation for the development of the electric vehicle industry.
Final chapter: a new chapter in the era of solid-state batteries
The breakthrough of solid-state battery technology means that the electric vehicle industry is about to usher in a profound change. Toyota's efforts and innovations have brought new hope to the entire industry, and the goal of halving battery size, cost and weight is no longer a distant dream.
With the breakthrough made by Toyota and other companies in the field of solid-state battery technology, the cruising range and charging speed of electric vehicles will also be qualitatively leaped, which will create more favorable conditions for promoting the popularization and development of electric vehicles. At the same time, the commercialization of solid-state battery technology will also bring new opportunities to the energy field, improve energy storage efficiency, and promote the application of clean energy.
On the road of technological innovation, Chinese scientists are also moving forward, not only injecting new impetus into domestic scientific and technological innovation, but also contributing important forces to the global energy revolution. The breakthrough of solid-state battery technology is the crystallization of the wisdom of Chinese scientists and a microcosm of the continuous rise of China's scientific and technological strength.
In the future, as Toyota and other companies put solid-state battery technology into commercial application, we have reason to believe that electric vehicles will usher in a new chapter, create a cleaner and more environmentally friendly way of travel for mankind, and promote the great cause of sustainable development. The vigorous development of solid-state battery technology is destined to become an important milestone in the electric vehicle industry, and will also inject new vitality into future scientific and technological innovation. Let's look forward to the arrival of the era of solid-state batteries.
