Toyota solid state battery out! 15 minutes full charge 500 kilometers, but mass production to wait 10 years?

The reason why pure electric vehicles have not been accepted by most of them until now is mainly due to their range and battery problems. At present, most of the pure electric vehicles on the market are used in the battery is ternary lithium batteries, in the current use of all types of batteries, ternary lithium batteries, energy density is the highest, and the reliability of certain verification. However, lithium ternary batteries are not the best.

As we all know, in addition to Li-ion ternary batteries, there are also types of batteries with higher energy density that have not yet been fully developed, and this type of battery is called a solid-state battery. This type of battery is called a solid-state battery, and it has a much higher energy density than lithium ternary batteries.

And just recently, Toyota, which has been less favorable to pure electric power, announced that it will debut its solid-state battery technology in 2021. The current solid-state battery prototype has been loaded and running, and was originally planned to be shown to the public during the 2020 Tokyo Olympics, but was delayed until 2021 due to the epidemic. According to the data obtained in the test, Toyota's solid-state battery prototype products in the charging speed is significantly better than lithium-ion batteries a lot, only 15 minutes can be charged from zero power to full power, range of 500 kilometers.

What makes solid-state batteries different from the batteries currently in vogue is that they no longer use an aqueous solution of electrolyte, thus reducing the risk of fire. Instead of liquid or polymer gel electrodes, solid-state batteries (as the name suggests) use solid-state electrodes and solid-state electrolytes. However, it is worth noting that solid-state batteries do not perform well at low temperatures and their long-term durability has been questioned in the past. These two aspects of the problem are why solid-state batteries have never been introduced, and the implication of Toyota's release is that it appears to have overcome both of these challenges.

Toyota currently holds more than 1,000 patents covering solid-state batteries, making it one of the automakers with the most patents on solid-state battery technology, and in addition to Toyota, there's another Japanese company, Nissan, whose first solid-state battery-powered electric car is likely to come out in 2028. Volkswagen is also reportedly close to 0-maybe starting to benefit from a partnership with a U.S. startup that will begin production of the batteries in 2025.

In the field of battery technology used in pure electric vehicles, solid-state batteries are seen as a pure electric vehicle development a major turning point. As mentioned earlier, solid-state batteries have significant advantages over traditional lithium-ion batteries in every way. It may not be a huge improvement in range, but its charging efficiency is several times that of traditional lithium-ion batteries, which actually increases the range on another level.

According to the information released by Toyota, it only takes 15 minutes to charge from zero to full, which is not much different from the time it takes to refuel a fuel car, even if the range is only 500 kilometers, which is more convenient than the current pure electric car.

In addition, Toyota said that this technology will be released in 2021, and has been carried in the prototype test, but only to know is that the prototype is a test vehicle, is not the same as the production car, that is, is still in the test stage of development. According to the current situation of each brand for solid-state battery R & D progress, even if Toyota is the fastest to realize the use of production vehicles, the fastest is expected to be in 10 years later.
