But having said that, compared with the lithium batteries commonly used, whether it is ternary lithium or lithium iron phosphate,

Both of these batteries have great shortcomings in temperature, and they are both afraid of cold and heat.

Therefore, this also leads to the need for battery protection and battery preheating, as well as additional heat dissipation treatment for the battery.

If you are not careful during use, the battery life will be greatly reduced.

The number of charges and discharges of these two batteries is only 800-1,000 times. Generally speaking, they can be used for eight or ten years.

But there are no absolutes in everything. This is just his theoretical data. In daily use, batteries are often charged and discharged with large currents.

This will cause the battery life to be halved, or degrade even more in harsh environments.

Due to the characteristics of graphene, it has good thermal and electrical conductivity, allowing it to work in harsh environments of -50-110°C.

It has good performance in both high and low temperature environments and will not cause much attenuation due to temperature.

However, the battery he created this time was different. He conducted careful research on the number of charge and discharge times and finally solved this problem.

Even if it is currently manufactured in the laboratory, the best lithium battery can be fully charged and discharged 3000-6000 times, which will not exceed 10,000 times.

But the battery he developed can be charged and discharged more than 10,000 times, reaching 50,000 full charge and discharge times.

And even after reaching this number of times, it does not mean that the battery is useless. It is just that the battery has partially decayed, but it can still ensure that the capacity is above 85%.

Previously, he introduced the charging and discharging and charging speed advantages of the battery he developed, and the most important capacity has also been greatly improved.

Since graphene can reach the atomic level, the energy density of the battery will also be greatly increased.

For the same 18650 model power battery, in the same volume, the energy density of the graphene battery is at least ten times higher.

So what will be the consequences? That is, the same 18650 battery, ternary lithium and lithium iron phosphate can achieve 2500-3400mAh.

But the energy density of graphene batteries is ten times that of theirs, which means it has a power capacity of at least 25,000mAh.

What will be the consequences of this? For a simple example, take Weihua’s foldable mobile phone. Its battery capacity is 4500mAh.

Someone has specifically tested it before, and it lasted 7 hours and 10 minutes playing Genshin Impact without any rest when fully charged.

If the battery of the same size were replaced with this one, it would have 45,000mAh. With ten times the capacity, the time would be 81 hours and 40 minutes.

When converted, it is more than three days. Don't underestimate these three days. This is the standby time tested in a high power consumption mode.

If it is used regularly, the standby time will be able to last for one day. If it is replaced with graphene, it will have ten days or even longer without charging.

It seems that in an instant, the standby time of mobile phones has returned to the Nokia era, an era where there was no need to charge the phone for more than a week.

With such data here, how do you compare other batteries to this one? Even if you break the rules, you still can't compare.

If such a battery is used in the electric motorcycles or electric cars he develops, what kind of effect will it have?

That will allow current cars to have ten times the power available. A car that can only travel 400 kilometers in the past will have a driving range of more than 3,000 kilometers.

Even if you keep the air conditioner or heater on on the road, you can still drive such a car from Peking to Hujiang at half the price.

Even an ordinary fuel vehicle can only travel 400-600 kilometers on a tank of fuel. However, an electric vehicle equipped with a graphene battery can actually be used and has a driving range of more than 1,500 kilometers.

Calculated in this way, it is even more impressive than a fuel vehicle.

After he developed this ultra-high-energy-density battery, his initial desire to build an electric motorcycle gradually faded away, and now he only wants to work towards an electric car.

Electric vehicles will definitely replace fuel vehicles in the future, as long as the problems of charging speed and battery capacity are solved, and now these two problems are directly solved by the battery he developed.

And in his mind, once this battery is mass-produced, the impact it will have can be said to be huge.

Many industries will face upgrading. In the fields of batteries, smartphones, mobile devices, computers, etc., it is not an exaggeration to say that it will bring revolution.

After he developed a complete device for the preparation of graphene, he also reduced the cost of this material from the name of black gold.

What are the main raw materials of graphene? You can tell from the name, graphite.

Within Kyushu, graphite reserves are huge and cheap, just like sand, the raw material for silicon wafers.

Although there are no reserves as large as sand, you can tell from the pencils we use in our daily lives that the reserves are huge.

Of course, after he developed the equipment for preparing graphene, he also had the ability to turn stone into gold.

Even if his research and development journey ends here, the results he has achieved are astonishing.

After the battery is developed, the corresponding energy input can also be developed.

The main factor that determines the charging speed is the input channel of the battery, but what about other than this? That's voltage and current.

As long as the battery can withstand it, increasing the voltage and increasing the current input can greatly speed up the charging rate.

The greater the charging current and the stronger the voltage, the greater the power of the charging pile.

There are also problems to be solved on the charger. During the high-rate charging process, the charger will also generate a large amount of heat due to its own resistance.

This requires the charger to also use low-loss superconducting materials, or materials that are extremely high temperature resistant and have excellent heat dissipation.

Superconducting materials are not yet within his reach. Even if he could develop them, he would not dare to actually do it in reality.

This requires him to start from another aspect, that is, materials with good heat dissipation and high temperature resistance, and the graphene he just developed has once again become the first choice.

This problem was also solved when graphene was added to the charger.

The two most important parts that determine the future of electric vehicles are solved by the graphene he developed.

As for the remaining problems, there are only two problems, one is the motor, and the other is the control system.

The control system is not actually a single function. The charging process and battery discharge require the participation of the control system.

When he got the battery and charger out, he also researched the control systems for these two parts.

As for the control system of the entire vehicle, it is necessary to integrate the control systems of all components together to form a complete control system.

This determined that this part was carried out at the same time as each component, so next he had to tackle the motor.

This is the main component that determines how fast the car can run, how much stuff it can pull, and how powerful it is.

It can be said that the batteries and chargers developed before are all used to provide services for the electric motors that will be manufactured now.

And the manufacturing of this kind of motor has also begun to touch on the design of the entire vehicle.

Whether the vehicle uses a single motor, dual motors, or multi-motor layout, these all determine the decisive factors such as the motor's power, appearance size, etc.

His research and development this time has become bigger and bigger. From the beginning, he just wanted to build an electric motorcycle, and later he added plans to manufacture electric cars.

Nowadays, the main target has shifted to electric vehicles, and the electric motorcycles at the beginning have no sense of existence.

For electric vehicles, the positioning this time is still at the mid-to-high-end level. Don’t ask why, it is entirely because of the addition of important technologies such as batteries and chargers.

Don't think that these technologies became useless after he invented them. This is all because of his cheating, so that he can achieve the current results so easily.

Now that the positioning has been determined, it is necessary to choose the direction of the vehicle model.

The technologies he now masters will make any model produced become a hit in the market, of course, if the appearance is not so ugly.

What he is facing now is the problem of specific positioning. Of course, it is not a bad choice.

For mid-to-high-end positioning, there are undoubtedly just a few types of models, including sports cars, SUVs, and most importantly, sedans.

Of course, these are not the only ones, there are also MPVs and light passenger cars, but these two types of passenger cars are used to convert RVs.

If the price reaches 600,000 to 800,000, and it is still a bare car without modifications, there will definitely not be many sales.

Therefore, MPVs and light passenger cars are excluded first, and the rest are easier to choose from.

Needless to say, sports cars are too high-end and will not have many sales. In the sports car market, there are many models that are losing money and making money, and are just serving as live advertisements for car companies.

Therefore, sports cars were also excluded, leaving only two types.

There is no doubt that both sedans and SUVs must be mid- to large-sized vehicles in order to be worth the price.

As a result, the range of vehicle models to choose from is greatly reduced, and electric vehicles are inherently targeted at young people.

So the choice was between a coupe and a technology-rich SUV that fit his vision.

Suddenly there were only two models left. Faced with a choice, he finally chose to reach out to SUVs.

He wants to create an SUV with high technological content, high playability, and extremely eye-catching appearance.

And there is still a very cool idea buried deep in his heart, but everything will have to be done after the mass-produced SUV is successfully developed.

What is it? In fact, it was also inspired by the Little Life animation he watched when he was a child.

Who hasn’t dreamed of having their own highly intelligent Formula One car when they were little?

Thinking of this, some middle school students shouted loudly: "The past is not a miracle, the real miracle is about to begin now."

I was still imagining the scene where I was sitting in Super Asrada.
