What changes graphene batteries can bring to the electric vehicle industry

The news of Yadea's launch of graphene batteries has frequently landed in industry headlines, becoming another example of technological innovation in the electric vehicle industry after the new national standard. Battery power has always been a major pain point in the development of the clamping industry, and the launch of Yadea graphene battery has met consumers' demand for high-performance batteries and led lead-acid batteries into the era of high performance.

After the implementation of the new national standard, Yadea's perfect layout in vehicle R&D and core electrical components has effectively promoted the technological revolution and industrial upgrading of the electric vehicle industry, and also demonstrated the strength and responsibility of the head brand.

For a long time, the battery life and slow charging speed of electric vehicles have plagued the industry and consumers, and how to solve the pain points of battery life, increase battery durability and improve battery charging speed have become a common issue that the industry needs to overcome. Under the watchful eye, Yadea graphene battery has become one of the most mature, practical and cost-effective battery solutions in the industry so far.

In the ** report, the advantages of Yadea graphene batteries have been elaborated. Compared with ordinary lead-acid batteries, Yadea graphene batteries have excellent performance in terms of battery life, fast charging, and improved battery life, and their comprehensive performance has been greatly improved. This achievement is completely revolutionary in the development process of lead-acid batteries.

If you simply compare electric vehicles with mobile phones, it seems inappropriate, but from the perspective of innovation alone, the revolutionary creation of Yadea graphene batteries in the field of power is like mobile phones from "Nokia" to the "iPhone" era, setting off a wave of terminal replacement.

The new national standard for electric vehicles has changed the industrial layout of the industry in many dimensions, and this transformation has also promoted the upgrading of the battery industry. Before the launch of Yadea graphene batteries, if consumers want to get higher endurance and stronger power, lithium battery power may be the most preferred, but the overall ** is also relatively high, which also affects the user's purchase and the promotion of dealers to a certain extent.

You don't have to wait long to recharge. The passing current of ordinary batteries is small, and the charging time is about 6-8 hours. The Yadea graphene battery with graphene composite super conductive paste has strong conductivity and can support 20A high-current charging and discharging.

With the help of a professional charger, Yadea graphene batteries can be fully charged to more than 80% in an hour. Even if the temporary car has no power, you can enjoy a long battery life just by waiting for a while.

Graphene batteries can make electric vehicles last longer and run longer.

Mainly look at the first day, the key to new energy vehicles is the battery, if the sodium-ion battery is really successfully developed and mass-produced, I don't know if the battery can be lowered, if it can, the three-minute fast battery replacement method of the car can be fully promoted like a gas station, so that as long as there are enough battery swap stations and charging piles, it can completely solve the problem of range and battery damage. In fact, as long as there is no major breakthrough in battery technology, it is difficult to improve the range, and the installation of solar panels on new energy vehicles may be a good supplement.

The graphene battery reconstructs the electrode microstructure, and the number of repeated charging and discharging has reached more than 1,000 times, and the life span is 3 times that of ordinary batteries, and it can be used for 7-8 years normally. Not only does it save the cost of replacing it, but you don't need to worry about battery life all the time.

Faster charging and safer charging carriers bring new opportunities for the promotion of electric vehicles.

The life span is 3 times that of ordinary batteries, and it can be used for 7-8 years normally. Not only does it save the cost of replacing it.

Looking at it now, it should make the technology more mature.

I think it can make the technology more mature.

A group of people who don't study batteries are here, graphene is sold by the gram, and according to the purity, it is not possible to pass thousands to tens of thousands of grams per gram. Yadea is noisy with the concept, fooling consumers, and the merchants on the market are arguing about the concept.

It should have brought innovation in technology.

Looking at it now, it shouldn't be a big change.

The changes are earth-shattering.

Charging electric vehicles is not a one-sided technology.

Graphene batteries are expensive and cannot be popularized yet.

In electric cars have not realized the technology electric bicycle can? No way.

It's basically on paper.

Does the emblem electric car have this battery.

Advantages of graphene battery:

1. The storage capacity is three times that of the best products on the market. A lithium-ion battery (whichever is the most advanced) has a specific energy value of 180 wh kg, while a graphene battery has a specific energy of more than 600 wh kg.

2. Electric vehicles powered by this battery** can travel up to 1,000 kilometers and their charging time is less than 8 minutes.

3. Long service life. It has four times the service life of conventional hydrogenated batteries and twice as long as lithium-ion batteries.

4. Light weight. The properties of graphene allow the weight of the battery to be reduced to half that of a conventional battery, which can improve the efficiency of the machine that loads the battery.

6. Faster charging speed, and more durable than lithium-ion batteries at high temperatures.

Graphene battery disadvantages:

1. At present, graphite has not yet reached the practical stage, and there is still a long way to go before mass production.

2. These graphene batteries on the market are not pure graphene batteries, they are only doped with some graphene-related technologies on the basis of lithium-ion batteries, and compared with traditional lithium-ion batteries, the performance improvement it brings is only a little bit.

In addition, the cost of graphene is very high, and its manufacturing process is also very high, and the manufacturing process of graphene batteries is still not mature enough, and it cannot reach the point of mass production when it is only in the laboratory stage.

3. The process characteristics are incompatible. That is, the specific surface area of graphene is too large, which will bring a lot of process problems to the dispersion and homogenization of existing lithium-ion batteries. If the battery factory adjusts the process to death, it will not be driven by enough profit margins brought by breakthrough progress in performance indicators.

Hello dear, I have made an answer to your question, is it like this, graphene batteries are good, graphene batteries can reach dozens of times the charging efficiency of lithium batteries. Huawei has done a test to charge 50% of the 3000 mAh graphene battery of the mobile phone in just a few minutes. This may be the best gospel for new energy vehicles in addition to the battery swap mode.

It's just that the safety requirements of automobiles are higher, and graphene batteries are currently only in the testing stage, and it will take a certain amount of time to mass-produce them in vehicles such as automobiles.

Precautions for the use of graphene batteries for electric vehicles, charging during the day can better control the time. After the graphene battery is used for half a year, it is recommended to deeply discharge the battery once a month, and then charge the electric vehicle battery after deep discharge, and the time is controlled at 12 hours. This will be of great benefit to the power recovery of the EV battery.

After the first charge, although it is not the first charge, but the second time is also a new car charge, at this time you can let the battery car when the power is about to run out, and then carry out a long charge, this charge can be maintained for 8-9 or even 10 hours, in order to let the battery car chemical reaction carry out a complete cycle.

Questions. Thank you.

Please close the upper right corner in advance, give me a thumbs up.

Graphene batteries are good.

This battery is a new graphene battery developed by Yadea's 100-person team that took three years and used four core technologies to integrate graphene and lead-acid materials.

Because graphene, as a new nanomaterial, has ultra-high thermal conductivity and electrical conductivity, graphene batteries use composite super conductive paste technology, which improves the utilization rate of plate reactants, has stronger power storage capacity, and the battery capacity is increased by 9% compared with ordinary batteries, and the comprehensive battery life is increased by 10%.

applications of graphene batteries;

1. Due to the characteristics of high conductivity, high strength, ultra-light and thin, the application of graphene in the field of aerospace and military industry is also extremely prominent. Not long ago, NASA developed a graphene sensor used in the aerospace field, which can detect trace elements in the earth's high-altitude atmosphere and structural defects on spacecraft. Graphene will also play a greater role in potential applications such as ultralight aircraft materials.

2. New energy batteries are also an important field for the earliest commercial use of graphene, in addition, the successful research and development of graphene super batteries has also solved the problem of insufficient capacity and long charging time of new energy vehicle batteries, which has greatly accelerated the development of the new energy battery industry.

In the case of a graphene electric vehicle battery equipped with a professional fast charging charger, the charging time of 1 hour can charge the power of the electric vehicle battery to about 80, and the power charged in this hour can allow you to ride 50 kilometers, that is to say, 10 minutes of charging can be more than ten miles.

The cycle life of graphene batteries can reach more than 1,000 times, which is 3 times that of ordinary lead-acid batteries, and if you look at the average frequency of charging once in three days, its use time can reach eight to nine years, so that the cost of daily travel is greatly reduced.

Ordinary lead-acid batteries are very vulnerable to damage and their performance will deteriorate under the drastic change in temperature, which is why it is felt that the electricity of electric vehicles is not durable in winter, while graphene batteries can maintain a stable discharge in the case of -20 -55.

The disposal of waste batteries for electric vehicles has also been a problem"It's hard to get old"Throwing it away will cause environmental pollution. The electrode grid of the graphene battery of electric vehicles adopts high-end industrial battery alloy technology and adds special rare earth elements, which is not only green and environmentally friendly, but also effectively inhibits the corrosion of the matrix and grain boundaries, and greatly improves the corrosion resistance.

Of course, even if it is green and environmentally friendly, waste batteries cannot be discarded at will, and handed over to professionals to dispose of, so that the waste battery can contribute its last value.

The answer is still good. Emma's graphene battery is about the same as Yadea in terms of service life, about 3 times that of ordinary batteries, and also supports 1 hour of fast charging. Even in a low temperature of minus 20 degrees Celsius, it can have a range of 58km.

So in general, there is not much difference between the two batteries, and the performance is very excellent.

Advantages of graphene batteries:

1) The power storage capacity is three times that of the best products on the market at present, the specific energy of lithium battery (whichever is the most advanced) is 180Wh kg, while the specific energy of graphene battery is more than 600Wh kg.

2) This battery-powered electric vehicle has a range of up to 1,000 kilometers and a charging time of less than 8 minutes.

3) Long service life, its service life is four times that of traditional hydrogenated batteries, and twice that of lithium batteries.

4) Light weight, due to the characteristics of graphene, the weight of the battery can be reduced to half of the traditional battery, which can improve the efficiency of the machine equipped with the battery.

Hope it helps, dear

Graphene electric vehicle batteries are relatively good and the technology is more advanced.

The success of the experimental stage of the new graphene battery will undoubtedly become a new development point in the battery industry. Battery technology is the biggest threshold for the vigorous promotion and development of electric vehicles, and the battery industry is in the stage where the development of lead-acid batteries and traditional lithium batteries has encountered bottlenecks.

Due to its unique properties, graphene has been called a miracle material, and scientists have even predicted that it will revolutionize the 21st century. Professor Colin Bailey, Vice-Chancellor and Vice-Chancellor of the University of Manchester, said graphene had the potential to revolutionise a wide range of applications, from smartphones and ultra-high-speed broadband to drug delivery and computer chips.

Application Brief

With the gradual breakthrough of mass production and large size and other problems, the pace of industrial application of graphene is accelerating, based on the existing research results, the first field to achieve commercial application may be mobile equipment, aerospace, new energy battery field.

Bendable screens at the Consumer Electronics Show have attracted much attention and become the development trend of mobile device displays in the future. The future market of flexible display is broad, and the prospect of graphene as a basic material is also promising.

The real graphene electric vehicle battery does not exist, and it is all borrowed from its concept for hype, but after the motor uses this technology, the charging current is indeed increased compared with the original, but the increase is limited, that is, the shortened charging time is not very obvious.

The graphene electric vehicle battery is just bragging, I changed this battery in December 2o19, it only takes about an hour to charge (ordinary chargers are not fast charging), the driving distance is less than 20 kilometers, ** is twice that of Tianneng, I want to ask what is good about graphene batteries?

In Liuzhou Tailing after-sales replaced a set of 880 yuan graphene battery, promised to use it for two years, the month can only last 10 kilometers, go to Tailing after-sales testing, after-sales said that it was broken, dismantled my graphene battery and put it in their store to repair, I installed a group of spare electricity in their store, and told me to go back and wait**.

Two days later, he asked me to change the battery, and replaced me with some ordinary worn-out batteries that were not graphene removed from other broken cars. Sad, I bought a brand new Tailing graphene pack for two years, replace it with some tattered play for me, the after-sales of Tailing Tram, is it appropriate for you to do this? I promise to describe it truthfully!
