Toyota, the world’s largest automaker, has announced plans to launch a new electric vehicle (EV) with a solid-state battery that could offer up to 900 miles of driving range and a 10-minute charging time by 20271. This breakthrough technology has the potential to revolutionize the EV industry and address some of the key challenges that have hindered the mass adoption of electric cars.

What are solid-state batteries and why are they better than lithium-ion batteries?

Solid-state batteries are a type of rechargeable battery that uses a solid electrolyte instead of a liquid or gel electrolyte as in conventional lithium-ion batteries. This has several advantages, such as:

  • Higher energy density: Solid-state batteries can store more energy per unit volume and weight, which means they can provide longer driving range for EVs.
  • Faster charging: Solid-state batteries can accept higher current rates, which means they can be recharged in minutes instead of hours.
  • Safer operation: Solid-state batteries eliminate the risk of fire or explosion caused by leakage or overheating of liquid electrolytes.
  • Longer lifespan: Solid-state batteries have less degradation and self-discharge, which means they can last longer and retain more capacity over time.

However, solid-state batteries also have some challenges, such as:

  • High cost: Solid-state batteries are more expensive to produce than lithium-ion batteries due to the complexity and rarity of the materials and processes involved.
  • Scalability: Solid-state batteries are difficult to manufacture in large quantities and sizes due to the technical and quality issues that arise when scaling up production.
  • Performance: Solid-state batteries have lower power output and lower operating temperature range than lithium-ion batteries, which means they may not perform well in high-speed or cold environments.

How did Toyota achieve this breakthrough?

Toyota has been working on solid-state battery technology for over a decade, and has filed more than 1,000 patents related to it2. The company claims that it has found a new material that simplifies the production of the solid electrolyte and improves its conductivity and stability3. This material also allows Toyota to use a bipolar structure for its battery cells, which reduces the number of components and increases the energy density4.

Toyota plans to introduce two versions of its solid-state battery EVs in the next few years. The first one will be a performance model that will use the same battery chemistry as its current bZ4X SUV, but will offer 20% more driving range (about 300 miles) and 20% lower cost. The second one will be a high-performance model that will use a new battery chemistry that will offer 50% more driving range (about 900 miles) and 10-minute charging time. Toyota expects to launch the performance model by 2026 and the high-performance model by 2027 or 20283.

What are the implications of this breakthrough?

Toyota’s announcement has generated a lot of excitement and curiosity in the EV industry and among consumers. If Toyota can deliver on its promises, it could have a significant impact on the market share, competitiveness, and innovation of EVs. Some of the possible implications are:

  • Increased consumer demand: Toyota’s new EVs could attract more customers who are interested in electric cars but are deterred by the current limitations of range, charging time, cost, and safety. Toyota’s new EVs could also appeal to customers who value environmental sustainability, as solid-state batteries have lower carbon footprint and higher recyclability than lithium-ion batteries.
  • Enhanced brand reputation: Toyota’s new EVs could enhance its brand reputation as a leader and innovator in green technology and mobility solutions. Toyota has already established itself as a pioneer in hybrid vehicles with its popular Prius model, but has lagged behind other automakers in EV development. Toyota’s new EVs could help it regain its edge and credibility in the EV market.
  • Stimulated competition: Toyota’s new EVs could stimulate competition among other automakers who are also working on solid-state battery technology or other advanced battery technologies. This could lead to more research and development, faster innovation, lower prices, and better quality for EVs. Some of the competitors include Honda, Volkswagen, Hyundai, Nissan, BMW, Porsche, Tesla, and startups such as QuantumScape and Solid Power.


Toyota’s new EV with a solid-state battery that could offer up to 900 miles of driving range and a 10-minute charging time is an ambitious and promising project that could change the game for electric cars. However, there are still many uncertainties and challenges that need to be overcome before this technology can be commercialized and widely adopted. Therefore, it is too early to say whether Toyota’s new EV will be a success or a failure, but it is certainly worth keeping an eye on.
