At present, cruising range and charging time are the biggest obstacles to the development of electric vehicles. The charging speed of 10 minute is still much longer than the refueling time of the fuel truck, but at least it is much faster than the current "one-time charging". In this war without smoke, Toyota is not fighting alone. Just last week, Volkswagen officially announced that it had developed a new set of solid-state batteries in cooperation with QuantumScape of California, so Volkswagen spent $200 million on it.
Toyota cooperated with Panasonic this time. At present, they hold more than 65,438+0,000 patents on solid-state batteries. Nissan said that it is also developing solid-state batteries and announced that it will bring a "non-analog" vehicle in 2028. At present, Toyota's main action is hydrogen power. Next, they will launch a new upgraded version of hydrogen power? Mirai. At the same time, Nissan will also launch its first pure electric SUV——Ariya.
At present, both Toyota and Nissan are supported by the Japanese government. According to statistics, the Japanese government is currently setting up a special fund of more than 2 trillion yen to support decarbonization technology. A large part of it is used to support the research and development of new solid-state battery packs. At present, two large Japanese mining and oil companies, Mitsui & Co., Ltd. and Chu Guang Sheng Xing, are building infrastructure to produce solid electrolyte.
At present, Japan is racing against time to launch a new generation of solid-state batteries with better performance than existing lithium-ion batteries before China and South Korea. Samsung announced that it has developed a solid-state battery pack that uses silver carbon instead of lithium ion. This prototype solid-state battery pack only has the capacity of the existing lithium battery pack, but its battery life has exceeded 500 miles (800 kilometers).
In China, "Made in China 2025" issued by the Ministry of Industry and Information Technology pointed out: "By 2025 and 2030, the energy density of power batteries in China needs to reach 400Wh/kg and 500Wh/kg respectively." ? The indexes correspond to 2-3 times of the average level of passenger car power battery 170Wh/kg.
China is in the process of developing from the second generation lithium battery to the third generation lithium battery. In the choice of cathode materials, China has shifted from lithium ferrous phosphate to ternary, and gradually developed to ternary with high nickel content. At present, the industrialization of anode materials is still dominated by graphite materials, and it is also transitioning to silicon-carbon anodes in the future.
Write at the end:
The competition for a new generation of solid-state batteries has sounded, and Toyota announced that it plans to produce a prototype of a new generation of solid-state batteries in 20021year. Therefore, we already know where the global automobile manufacturers will lead the research and development technology in the future.
