The Japanese company Toshiba starts the production of its new revolutionary battery for electric cars. This evokes an innovative chemistry and offers a large lifespan, as well as a very fast charge. We will explain everything below.
Batteries are one of the most important elements on an electric car. Moreover, the latter represents an average of 40 % of the total price of a car, which oscillate between $ 7,000 and $ 25,000, depending on the model. They are those who take care of it Optimal autonomy As well as a quick load.
A new promising technology
Over the years, manufacturers, but also manufacturers of equipment, remain Offer new innovative technologies. The goal? Make electric cars more versatile and practical. And above all reassure motorists. Because they are still very numerous at the moment to not want to venture. In question, insufficient autonomy, an overly slow load and not enough terminals. All this is now incorrect. And this thanks to certain companies that bring about a revolution in the sector.
This is, for example, the case of Toshiba. The Japanese company announces in one communique Just published after the production of a brand new battery. Better yet, the first samples have already started to be delivered. But what is it? In fact, this revolutionary accumulator uses a whole new technology. Specifically, it is the very first first with which you will be equippedAn anode composed of Niobium and Titanium (NTO).
On the classic LFP (lithium – iron – phosphate) batteries the last is made of graphite. But what does this change change in concrete terms? Well many things. You must know that this new solution offers An energy density similar to the LFP. If Toshiba has not specified that of the new battery, it is generally around 200 WH/kg. It is lower than proposed NMC cells (nickel – manganese – cobalt). However, the interest of the battery in Niobium – titanium is elsewhere.
Indeed, where this new technology is very strong, it is mainly through His long service life. According to teams from the Japanese company, the recently unveiled battery can cash Up to 15,000 load-upload cycles. That is just huge, because it is approximately 6 million kilometers, for example with a range of 400 km. Even with repeated fast partial taxes, which is generally not good for cells. In general, it is advisable to fill the battery in one go by 10 to 80 %. And for small taxes, the assets must be limited if possible.
A very fast load
Toshiba announces that the volume of its new cells isEnviron 350 WH/Liter. The gravimetric density is 130 WH/kg. What is also average, without being very high. High density makes it possible to offer better autonomy, Without having to install a larger battery. The production costs remain, as well as the total weight. According to the supplier of equipment, every scib lithium-ion nto cell weighs around 860 grams.
But that is not all, because this new technology also offers a particularly fast charging. The load capacity is announced at 5C, so that the battery can be filled up to 80 % in just 10 minutes. Moreover, the operating temperature range is particularly wide. It is indeed between -30 and 60 degrees. A real Tour de Force, because we know that extremely hot or have cold consequences for autonomy and loading speed.
Toshiba announces that deliveries of his first samples of his new cells will be able to start soon. The Japanese supplier also remembers that ” The frequent tax on designated points along the journey reduces the number of batteries installed, while the long service life of the services should lower the total possession costs by reducing the need for frequent batteries as a result of demolition ». She confirms that it is not necessarily essential to have a great autonomy. That offered by his new battery remains unknown for the time being.
