Now all car manufacturers manufacturing new energy models are looking for the same "holy grail", a car that can last for nearly 500 kilometers, only takes 10 minutes to charge, does not require a huge heating and cooling system, and can cycle more than 800 times (nearly 400,000 kilometers) can still maintain 80% charging capacity, and more importantly, it is not prone to spontaneous combustion. This is the prospect of the development of solid-state batteries. Well, Toyota will bring you good news. It has officially announced that it will release a new solid-state battery pack prototype next year for the above scenario.
You may not believe it, but please don’t close the page. Master Jiao will share the news he knows with everyone.
At present, cruising range and charging time are the biggest obstacles to the development of electric vehicles. Although the 10-minute charging speed is still much longer than the refueling time of a fuel vehicle, it is at least better than the current "one-time charging" It's too fast. In this war without gunpowder, Toyota is not fighting alone. Just last week, Volkswagen officially announced that it had cooperated with California-based QuantumScape to develop a new set of solid-state batteries, for which Volkswagen spent US$200 million.
Toyota is cooperating with Panasonic this time. They currently hold more than 1,000 solid-state battery technology patents. Nissan says it is also developing solid-state batteries and claims it will bring a "non-analog" vehicle in 2028. At present, Toyota's main action is on hydrogen power. Next they will launch a new and upgraded hydrogen-powered Mirai. At the same time, Nissan will also launch its first pure electric SUV-Ariya.
From the current point of view, whether it is Toyota or Nissan, they 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 portion of this is used to support the development of new solid-state battery packs. Currently, two large mining and oil companies in Japan, Mitsui & Co. and Idemitsu Kosan, are building infrastructure for the production of solid electrolytes.
Japan is currently racing against time to launch a new generation of solid-state battery packs that are better than existing lithium-ion battery packs before China and South Korea. Samsung has announced the development of a solid-state battery pack that uses silver carbon instead of lithium ions. This prototype solid-state battery pack has only the same capacity as existing lithium battery packs, but has a range of more than 500 miles (800 kilometers).
In China, the "Made in China 2025" issued by the Ministry of Industry and Information Technology states: "By 2025 and 2030, the energy density of my country's power battery cells must reach 400Wh/kg and 500Wh/kg respectively." Indicators They respectively correspond to 2-3 times the current average level of passenger car power battery cells of 170Wh/kg.
Our country is in the process of developing from the second generation to the third generation of lithium batteries. In terms of the selection of cathode materials, my country has shifted from lithium iron phosphate to ternary, and has gradually developed towards high-nickel ternary. The current industrialization of anode materials is still focused on graphite materials, and the transition to silicon-carbon anodes is also underway in the future.
Written at the end:
The race for a new generation of solid-state battery packs has begun, and Toyota has announced plans to produce prototypes equipped with a new generation of solid-state battery packs in 2021. Therefore, we already know where global automakers will lead R&D technology in the future.
