The carmaker predicts that the mileage of electric vehicles powered by solid-state batteries will be twice that of the current lithium-ion battery chemicals, and they can be fully charged in just 65,438+00 minutes. 65,438+0,000 patents related to solid-state batteries.
Toyota seems to be far ahead of other Japanese automakers (according to reports, Nissan plans not to actually test solid-state batteries before 2028), and the country's auto suppliers seem to be stepping up production.
According to reports, Mitsui Mining Company (Mitsui? Mining? And then what? Smelting) (also known as Mitsui Golden Foot) will establish a pilot facility to produce electrolyte for solid-state batteries. According to the report, the plant is located in the existing R&D center in Bangaki Prefecture, Japan, and will be able to produce "tens of tons" of solid electrolyte from next year, enough to meet the needs of the prototype.
The timetable discussed in the report is higher than the suggestions made by Toyota executives this summer. Keiji, Executive Vice President of Toyota Powertrain Division? In an interview with Automotive News in July, Keita said that the limited production of solid-state batteries will begin in 2025.
The report also implies that solid-state batteries can greatly improve energy density. This echoes Samsung's statement earlier this year, indicating that Samsung's solid-state technology can double the energy density.
Solid state batteries have become a trend of battery manufacturers. Apple iPhone manufacturer Foxconn is studying the solid-state battery for electric vehicles to be launched in 2024, as well as the Volkswagen-supported QuantumScape (former Tesla Chief Technology Officer JB? Board member Straubel recently said that its battery technology may be close to being deployed in electric vehicles.
However, Tesla himself believes that solid-state technology still has a long way to go. The company is looking for other technologies to achieve higher energy density, longer service life and lower manufacturing costs.
In China, there are news reports that FAW, BAIC and SAIC have invested in solid-state battery enterprises. Almost all powerful battery companies are developing solid-state batteries, while the start-up solid-state battery companies are desperate. Of course, some OEMs have laid out in advance, hoping to regain the right to speak; Some enterprises have concerns about the short-term development of solid-state batteries, and they are still waiting to see before they have a perfect product.
When analyzing this phenomenon, an industry insider said that car companies are enthusiastic about investing in solid-state battery companies. One is optimistic about the prospect of this technology, and the other is to avoid repeating the mistakes of liquid batteries. "Avoid another monopoly battery company and weaken the right to speak of car companies." In the words of this person, this time the car companies will enter the market in advance.
In any case, solid-state batteries are the mainstream route of the next generation of power batteries recognized by both academia and industry. The development of lithium battery is full of difficulties, which has experienced twists and turns in the middle, leading to the great prosperity of lithium-ion battery stage. However, the next stage of lithium battery development is to return to the route of metal lithium battery and come to the runway of solid-state battery. Which car company do you like?
