Chapter 170: Terror Graphene

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

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

So this also leads to the need for battery protection and battery preheating, and also to do additional heat dissipation treatment for the battery.

If you are not careful during use, it will cause a significant reduction in battery life.

The charging and discharging times of these two batteries are only 800-1000 times, and generally speaking, they can be used for eight or ten years.

However, there is no absolute, this is just his theoretical data, in daily use, the battery is often charged and discharged with high current.

This can result in the battery life being halved or even more attenuated in harsh environments.

Due to the characteristics of graphene, it has good thermal and electrical conductivity properties, so that it can work in the harsh environment of -50-110 °C.

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

However, this time he made this battery is different, he specially studied the number of charge and discharge, and finally solved this problem.

Even if it is currently manufactured in the laboratory, the best lithium battery has a complete charge and discharge of 3000-6000 times, which will not exceed 10,000 times at all.

However, the battery he developed has been charged and discharged more than 10,000 times, reaching 50,000 times of complete charge and discharge.

And even after reaching this number of times, it does not mean that the battery is wasted, but the battery is partially attenuated, but the capacity can still be guaranteed to be more than 85%.

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

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

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

What will be the consequences of this? That is, the same 18650 battery, ternary lithium and lithium iron phosphate can do 2500-3400mAh,

But the energy density of graphene batteries is ten times that of them, which is at least 25,000mAh.

What will be the result? For example, if you take Weihua's folding phone, it has a battery capacity of 4500mAh.

Someone has tested it before, and I ran Genshin Impact without rest when fully charged for 7 hours and 10 minutes.

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

That's more than three days, but don't underestimate these three days, this is the standby time tested in high power consumption mode.

If you use it normally, you will be able to use it for a day, and if you change it to graphene, you will have 10 days, or even more without recharging.

It seems that in an instant, the standby time of mobile phones has returned to the Nokia era, the era when you didn't have to charge your phone for more than a week.

With such data here, how do you compare to other batteries with this? Even if you say that the sky is broken, you can't compare it.

What would happen if such a battery was later used in his electric motorcycles or electric vehicles?

That's going to make today's cars 10 times more chargeable, and cars that can only run 400 kilometers will travel more than 3,000 kilometers.

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

Even if it is an ordinary fuel vehicle, a tank of fuel can only travel 400-600 kilometers, and an electric vehicle with a graphene battery can actually be used, with a mileage of more than 1,500 kilometers.

In this way, it is even better than a fuel car.

After he developed this ultra-high energy density battery, his desire to build an electric motorcycle at the beginning gradually died, and now he wants to work electric vehicles.

Electric vehicles will definitely replace the position of 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 in front of the batteries he has developed.

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

Many industries will face upgrades, and it is not an exaggeration to say that they will bring about a revolution in the fields of batteries, smartphones, mobile devices, computers, etc.

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

What is the main raw material of graphene? As you can tell from the name, graphite.

In Kyushu, the reserves of graphite are huge, and the price is low, just like the raw material sand of silicon wafers.

Although it is not as large as sand, we can tell with the pencil we use in our daily life that the reserve is huge.

Of course, after he developed the preparation equipment of graphene, he also had the ability to turn stones into gold.

Even if this is the end of his R&D journey, the results achieved are awesome.

After the development of the battery, the relative energy input can also be developed.

The main factor that determines the charging speed is the input channel of the battery, but what about 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 larger the charging current, the stronger the voltage, and the greater the power of the charging pile.

There are also problems to be solved in the charger, and in the process of charging at high rate of the charger, a large amount of heat will also be generated due to its own resistance.

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

Superconducting materials are not yet a field that he can reach now, and even if he can develop them, he doesn't dare to really make them in reality.

And 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.

It is also when graphene is added to the charger that this problem is also solved.

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

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

In fact, the control system is not a single function, the charging process and battery discharge need to be involved in the control system.

He also studied the control system of the two parts when the battery and charger were all out.

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

This determines that this part is carried out in the same way as each component, so he will tackle the electric motor next.

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

It can be said that the batteries and chargers that have been developed before are all for the electric motors that will be manufactured now.

And the manufacture of this motor has also begun to touch the design of the whole vehicle.

The whole vehicle is a single-motor, dual-motor, or multi-motor layout, which determines the power, appearance and other decisive factors of the motor.

His research and development this time has been getting bigger and bigger, from the beginning just to get an electric motorcycle, and then added the manufacturing plan of electric vehicles.

Now that the main goal has shifted to electric vehicles, the electric motorcycles at the beginning have no sense of existence.

For electric vehicles, this positioning is still at the mid-to-high-end level, don't ask why, it's all because of the addition of important technologies such as batteries and chargers.

Don't think that these technologies have become rotten because of him, this is all because he opened the hanging, so that the current results can be so simple.

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

The technologies he has mastered now will make any kind of produced model a hit on the market, of course, when the appearance is not so ugly.

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

In the mid-to-high-end positioning, there are undoubtedly several models, sports cars, SUVs and the most important sedans.

Of course, it's not just these, there are MPVs and light buses, but these two types of passenger cars are used to convert into RVs.

If the price reaches 60-800,000 yuan, or an unmodified bare plate car, there will not be much sales.

So MPVs and light buses are excluded in the first place, and the rest are easy to choose.

Needless to say, this kind of model is too high-end, and there will not be much sales, and there are many models in the sports car market that are losing money and making money, just as a live advertisement for car companies.

So sports cars were also excluded, and there were only two types left.

Sedans and SUVs undoubtedly need to be mid-to-large cars to make the price worthwhile.

In this way, the range of models selected is greatly reduced, and electric vehicles are congenitally oriented to young people.

Then the choice is a coupe, and an SUV with a sense of science and technology is in line with his vision.

For a while, there were only two models left, and when faced with a choice, he finally chose to reach out to the SUV.

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

And in his heart, there is a particularly cool idea buried deeply, but everything will be done after the successful development of a mass-produced SUV.

What is it? In fact, it was also the inspiration he got from the small day animation he watched when he was a child.

Who hasn't fantasized about being able to have their own, a highly intelligent formula when they were young?

Thinking of this, I unconsciously shouted in a loud voice: "The past is not a miracle, and the real miracle is only about to start now." ”

I'm still fantasizing about myself sitting inside Super Aslarda.
