Toyota Is Road Testing a Prototype Solid State Battery EV

Solid state batteries could be a leap forward for electric vehicles, and Toyota just showed them in a running, driving car.

Despite being ahead of the curve with hybrids, Toyota has taken smaller steps towards the world of battery electric vehicles. That could be changing, however, with the company committing to spend $13.6 billion on battery technologies by the end of the decade. The company is investing not just in next-generation lithium cells, but also revolutionary solid-state battery technology. Toyota went so far as to give us a vanishingly short look at something special—a prototype vehicle actually running and driving with solid-state batteries.
The vehicle shown in the video appears to be a version of Toyota's LQ Concept, which first debuted at the 2019 Tokyo Motor Show as an AI and self-driving demonstrator. Since then, it's had a starring role in a series of commercials for the Tokyo Olympic Games. Thus far, it was simply reported to be a "battery electric vehicle" however in this release, it bears a large decal announcing its "All-Solid-State" battery. Far from a static model, the prototype was filmed driving down the road under its own power.

Rumors of Toyota revealing a prototype vehicle with solid-state batteries first dropped in late 2020, according to contemporary reports from Nikkei Asia. In today's announcement, Chief Technology Officer Masahiko Maeda revealed that Toyota first built the prototype in June last year, driving the vehicle on a test course to collect performance data. Speaking to The Drive, Toyota's Vice President of Mobility Communications Shiro Tachimoto stated that "Based on that data, we continued to make improvements, and in August last year, we obtained license plate registration for vehicles equipped with all-solid-state batteries and conducted test drives."

It's an exciting development, as solid-state batteries are a potentially game-changing technology. By replacing liquid electrolytes used in current batteries with solid material, the batteries are far less flammable which allows them to run in a wider temperature window. It's thought that this could allow solid-state batteries to achieve greater power delivery as well as faster charging times, due to the lower risk of thermal runaway leading to fiery destruction. Additionally, there are potential gains to energy density too, which could lead to lighter vehicles with longer range.

However, solid-state battery technology has been a difficult nut to crack. Creating a solid-state battery that is robust, and can stand up to the rigors of automotive use has proven challenging. The new batteries must also hold up to repeated charge and discharge cycles without failure if they are to serve as a reliable power source for electric vehicles. In the same vein as their lithium-ion forebearers, there are also manufacturing issues to contend with. Hundreds of gigawatt-hours of battery capacity will be needed for future EVs, so companies must figure out how to produce high-performance solid-state batteries in huge numbers while keeping costs affordable.

Thus far, we've seen very few examples of running, driving vehicles powered by solid-state batteries, even in prototype form. Mercedes-Benz has developed the eCitaro bus to run on solid-state cells, however caveats in their care and maintenance keep them from being truly market-ready. Outside of that, most other manufacturers are yet to show their hands. BMW is betting heavily on the technology, promising only to reveal prototypes before 2025. Meanwhile, early proponent Fisker dropped its solid-state plans entirely earlier this year.

It's an impressive feat for the Japanese automaker, and one that bodes well for its push towards solid-state technology in future. With reports the company wishes to launch a solid-state vehicle in the early 2020s, it has its work cut out for it. Whether it can master the cutting-edge technology before its rivals will be borne out in due time.

Call me when they have an electric or hybrid 4Runner.

toyota has been lobbying hard against EVs and have been hyping up their hybrid vehicles a lot, looks like they finally opened their eyes to what the world wants. i would be happy to see toyota crash and burn just because they wanted to hold the world back for their own gain.

Will electric vehicles ever be able to match upto the combat prowess of the indestructible Toyota pickup?

You mean like nokia phone? Nobody think an indestructible handphone is the benchmark. But how much function, smart and smooth operation it can experience from it.

No wonder Toyota or Nokia are left behind in modern era.

Toyota is still king of robust pickup trucks tho bro. Land cruiser is still unbeatable.

Nokia also claim they are unbeatable in handphone 15 years and guess what.... Time will change. Things will not be stagnant.

Toyota had been pushing for hydrogen for the longest time and it may have been the right strategies at one point since EV's don't the cleanest/environment friendly supply chain. Now they are finally seeing the light, kinda like Blue Ray versus DVD debate when Blue Ray was a superior product.

Samsung overtook Nokia long ago bro.

That is not the point. Samsung never get into a domination factor like Nokia did 15years ago. Nobody predict a giant like Nokia can failed 15 years ago. Just like how u think Toyota is impossible to fail in automobile.

We are going into an era of electric and autonomous, smart vehicle times. Combustion engine is sure to go due to the carbon emissions. Toyota just like Nokia seems slow to react the changing times.

Hydrogen will be failure, why? Becos the cost to setup refuel station is enormous. Nobody bother to setup such facilities worldwide.

While for electricity, the cost to setup a charging station is cheap, just get from grid. You can even charge at home if u have a garage.

We are now going into solid state battery times. The supply chain for EV will only turn cleaner and better. Look at current most advance blade battery. A cobalt, nickel free battery. Slowly with improving technology. You don't even need lithium.

Toyota make huge Bet on the technology as it is so expensive to make one. Better perfecting current technology that uses lot of Nickle

Challenges[edit]
Cost[edit]
Solid-state batteries are traditionally expensive to make[48] and employ manufacturing processes thought to be difficult to scale, requiring expensive vacuum deposition equipment.[7] As a result, costs become prohibitive in consumer-based applications. It was estimated in 2012 that, based on then-current technology, a 20 Ah solid-state battery cell would cost US$100,000, and a high-range electric car would require between 800 and 1,000 of such cells.[7] Likewise, cost has impeded the adoption of solid-state batteries in other areas, such as smartphones.[44]

Temperature and pressure sensitivity[edit]
Low temperature operations may be challenging.[48] Solid-state batteries historically had poor performance.[9]

Solid-state batteries with ceramic electrolytes require high pressure to maintain contact with the electrodes.[49] Solid-state batteries with ceramic separators may break from mechanical stress.[7]

Dendrites[edit]

Lithium metal dendrite from the anode piercing through the separator and growing towards the cathode.
Solid lithium (Li) metal anodes in solid-state batteries are replacement candidates in lithium-ion batteries for higher energy densities, safety, and faster recharging times. Such anodes tend to suffer from the formation and the growth of Li dendrites.[50]

Dendrites penetrate the separator between the anode and the cathode causing short circuits. This causes overheating, which may result in fires or explosions from thermal runaway.[51] Li dendrites reduce coulombic efficiency.[52]

Dendrites commonly form during electrodeposition[53] during charge and discharge. Li ions combine with electrons at the anode surface as the battery charges - forming a layer of lithium metal.[54] Ideally, the lithium deposition occurs evenly on the anode. However, if the growth is uneven, dendrites form.[55]

Stable solid electrolyte interphase (SEI) was found to be the most effective strategy for inhibiting dendrite growth and increasing cycling performance.[52] Solid-state electrolytes (SSEs) may prevent dendrite growth, although this remains speculative.[51] A 2018 study identified nanoporous ceramic separators that block Li dendrite growth up to critical current densities.[56]

I'm not postulating that Toyota is too big to fail. I'm just saying will electric vehicles be as robust as Toyota pickups offroad capabilities. These are vehicles that have won entire wars. Top Gear demonstrated perfectly how these vehicles are indestructible.

The world is ever changing. The one who failed to adopt faster and react faster will doomed to fail.

It would be ironic if the batteries were made from lithium from Afghanistan. At some level, Toyota workers and executives must be proud their vehicles have earned a reputation for ruggedness, even if they can’t reference it directly.
