Toyota plans to launch a super all-solid-state battery pure electric vehicle in 2027, which can travel 1,200 kilometers in 10 minutes of charging

Toyota plans to launch a pure electric vehicle using an all-solid-state battery in 2027. It can be known that this model has lightning-fast charging speed and long-lasting cruising range. It only takes 10 minutes of charging to allow the vehicle to travel 1,200 kilometers.

According to the editor’s understanding, Toyota revealed this strategic plan at a recent technical briefing meeting. According to the company's chief technology officer and vice president Hiroki Nakajima, they have successfully solved the durability problems faced by all-solid-state batteries and found suitable alternative materials. We have found a high-quality material that is guaranteed to keep up with the trends of the times and will surely enable the practical use of all-solid-state batteries. ”

Different from the current mainstream liquid lithium batteries, all-solid-state batteries use pure solid electrolytes, which have the characteristics of fast charging and long cruising range. However, since the electrolyte and solid electrode must be closely combined and cannot be separated, the electrode is During the charging and discharging process, it will expand and contract repeatedly, resulting in the separation of the electrolyte and the electrode. Traditional solid-state batteries can only be charged and discharged from a dozen to a few hundred times, which is not enough to meet the thousands of times needed for commercialization.

Toyota said they have found a suitable alternative material to solve the problem of long-term charge and discharge of all-solid-state batteries, thus achieving large-scale commercialization of the battery. The report pointed out that Toyota is It has shown leading advantages in the research and development of all-solid-state batteries and has more than 1,000 related patents. In the summer of 2020, Toyota successfully applied all-solid-state batteries to vehicles and conducted driving tests. Toyota plans to strengthen research and development work to achieve the goal of recharging The goal is to drive about 1,500 kilometers in 10 minutes.

However, the current manufacturing cost of all-solid-state batteries is relatively high. According to estimates by Japanese professional organizations, the manufacturing cost of all-solid-state batteries (sulfide type) per kilowatt hour is 60,000 to 350,000 yen, which is 4 to 25 times that of existing lithium-ion batteries (14,000 yen). Reducing manufacturing costs is still a major challenge for the promotion of all-solid-state batteries.

Except Toyota , other automakers are also making progress in the field of all-solid-state batteries. It is said that Nissan plans to launch an electric vehicle equipped with a self-developed all-solid-state battery by 2028, while BMW plans to publicly display an experimental model equipped with an all-solid-state battery before 2025. , and plans to achieve mass production by 2030. The future development of electric vehicles will open up broader development prospects due to the competitive R&D and commercialization processes of major automobile manufacturers.
