Toyota Motor Corporation Develops Next Generation Electric Vehicle Based on All-Solid Battery with 1,200km on a 10-minute charge

 

Toyota's all-solid battery technology innovates as the world's largest automobile market share

​ Toyota unveiled the development of fluorine ion-based all solid batteries in a paper jointly published with Kyoto University, Tohoku University, and Tokyo University of Science and Technology (Tokyo University of Technology) in 2025. The technology is a solid battery that increases stability of fire protection lights, reduces weight by nearly half, and increases energy efficiency by three times, opening the possibility of 1,200 kilometers of driving on a 10-minute charge.

Impact on Automotive, Battery Industry

​ Toyota plans to start test production at its plant in Shizuoka Prefecture in 2026 and start mass production from 2027 to 2028. The supply of all-solid batteries can see the mobility emergency structure that can replace new technologies. After 2030, it is expected to contribute to the exceptional manpower, energy storage systems (ESSs), and the spread of new and renewable energy.

All-solid battery, high energy density, efficiency and reliability

​ One of the biggest problems with electric cars right now is the energy density of lithium-ion batteries. Energy density refers to the amount of energy a battery can store relative to its size and weight. This limits the driving distance and performance of electric vehicles.

​ All-solid state batteries use solid electrolytes, which allow them to move ions quickly and have excellent resistance to high voltage and temperature. These characteristics allow all-solid-state batteries to supply more power in smaller forms, suitable for fast charging and discharging. Toyota aims to commercialize all-solid-state batteries between 2027 and 28 and initially planned to introduce them to hybrid electric vehicles (HEVs), but is now focusing on the next generation of electric vehicles.

​ Toyota's first all-solid state battery can charge more than 80% in 10 minutes and has a mileage of about 1000 km, a 20% increase over the performance battery. It is also developing a higher specification lithium-ion all-solid-state battery with a goal of improving mileage by 50% compared to existing batteries.

The popularization of electric vehicles has become a reality with charging in 10 minutes and driving distance of more than 1,200 kilometers

​ One of the biggest obstacles to the popularization of electric vehicles is charging time. Even with the introduction of fast charging technology, lithium-ion batteries take a long time to charge, especially for long-distance vehicles. This makes long-distance driving uncomfortable and is the reason for choosing a conventional internal combustion engine car.

​ According to Toyota researchers, all-solid state batteries are expected to significantly shorten the conventional charging time. Toyota's all-solid-state battery technology can be charged in minutes, not hours, like conventional lithium-ion batteries. This fast charging can be a game changer for electric cars, making them as convenient as conventional gasoline cars, which only take a few minutes to fill up.
