New energy vehicles are definitely the trend of the future, but as a manufacturing field, there must be a lot of technical difficulties.

Ma Tian was collecting information in the laboratory, his eyes solemn.

When it comes to new energy vehicles, everyone may be most familiar with pure electric vehicles, but there are more than one kind of new energy vehicles, as well as gasoline-electric hybrids, solid-state fuel cells such as hydrogen energy, methane and other types.

Ma Tian is also thinking about what kind of research to start with.

After thinking about it, Ma Tian still decided to make a transition from the hybrid of oil and electricity, because he was afraid that pure electric would be too advanced and people would not be able to accept it, and there was also the problem that the construction of charging piles was too late.

As for solid-state fuel hydrogen batteries, etc., Ma Tian's knowledge told him that this is the direction of technological breakthroughs in the future, and this kind of car should not be popularized now, because the cost of transportation and storage is too high, and it will be difficult to popularize these two problems without solving them.

decided to engage in gasoline-electric hybrid first, and Ma Tian also took immediate action and prepared to break through the battery by himself.

Conventional batteries are mainly divided into ternary lithium batteries, lithium iron phosphate batteries, nickel-metal hydride batteries, etc., each with its own advantages and disadvantages.

But Ma Tian definitely doesn't consider them, he wants to develop new batteries by himself to solve problems such as battery life and fast charging.

Ma Tian's research direction is solid-state batteries, and the so-called solid-state batteries refer to lithium-ion batteries using solid-state electrolytes.

Different from the lithium-ion batteries and lithium-ion polymer batteries commonly used today, the solid-state battery is a battery that uses solid electrodes and a solid electrolyte, and the biggest difference from the current mainstream traditional lithium-ion batteries is the electrolyte.

Solid-state batteries use a solid electrolyte instead of the electrolyte and separator of traditional lithium-ion batteries.

Compared with liquid batteries, it has the advantages of faster charging speed, greatly improved energy density, higher safety, low temperature and no fear of power diving, longer cycle life, and reduced demand for thermal management.

Of course, it is naturally very difficult to develop such a good thing.

The first difficulty in the development of solid-state batteries is the interface contact between the electrode and the electrolyte, which has changed from the original solid-liquid contact to solid-solid contact.

In the process of cycling, due to the problem of dendrites, it is easy to cause stress accumulation, electrochemical performance attenuation, and even lead to the appearance of cracks in serious cases, and the battery capacity will decay rapidly as soon as cracks appear, and the cycle life will naturally be poor!

In addition, solid-state batteries also require electrode materials with good stability and film-forming properties.

The final difficulty is packaging, most of the lithium-ion batteries on the market use hot melt adhesive packaging technology, which has high uncertainty and cannot be directly used in solid-state batteries.

Once the battery is inefficient or recycled due to the failure of the packaging structure, the use effect of the battery will be affected.

Knowing this knowledge, Ma Tian also began a new round of retreat in the laboratory, as a circular warrior who has reached Lv3 in electronics, materials science, physics, etc.

Ma Tian said that he was the second researcher in the world, and no one should dare to say first in front of him.

The only thing lacking is inspiration in the dark! After all, this involves materials science, and materials science is sometimes called lottery science, and if you win, you will be a big prize, and if you don't win, you will thank you for your patronage.

But Ma Tian is rich, and he can smoke more than 100 million times.

After a month in the laboratory, Ma Tian finally "pumped" a good material LiSiS! It consists of lithium metal as an anode, silicon nanotubes, and a proprietary sulfur crystal solid electrolyte.

In the experimental environment, its energy density is more than 5 times that of ternary lithium battery, and it is very stable!

A week later, Ma Tian came out of the customs with his solid-state battery and named it "Tianming Battery".

Compared with liquid batteries, it not only has the advantages of high safety, long cycle life, wide temperature range, etc., but also its energy density has reached an astonishing 500Wh/Kg, a single charge range of more than 1400 kilometers, and supports fast charging, which can be fully charged in half an hour!

The battery is solved, and now the first prototype car is being built.

Ma Tian came directly to the R&D department of Xiaolanche and called Su Xihua and others for a meeting.

The R&D department of Little Blue Car has recently been led by Su Xihua, a doctor of engineering and mechanics, but all kinds of bicycles have been built.

There are weight-bearing bikes that are designed for exercise, tandem bikes that can be ridden by two people but are only promoted on campus and in the suburbs for safety, and moped bikes for school and work.

Even the appearance and style have changed greatly, for example, on campus, in order to fit the aesthetics of girls, there are cute big eyes on the handlebar.

Anyway, now the shared bicycle is left with Tianyu Xinghai's family, and there is no need for an independent style, so it's okay to try it this way.

Once launched, it was also praised by everyone!

When Su Xihua heard Secretary Ma Tian's message for a meeting, he also put down the wrench in his hand and came to the conference room with several main engineers, and Ma Tian was already sitting in the main seat.

"Mr. Ma!" The crowd greeted each other and sat down in order.

Ma Tian first looked at the circle of people, and said directly: "During this time, you handed over your work and went to build a car with me?" ”

"Build a car? Mr. Ma, are you talking about cars? Su Xihua took the lead and asked.

Ma Tian nodded: "That's right, it's a car!" ”

Hearing Ma Tian's affirmative answer, Su Xihua was also excited in his heart, as a doctor of engineering and mechanics, he had long been bored building bicycles during this time, because the difficulty of the challenge was too low.

Originally, he was ready to leave after designing the last batch of bicycles, but he didn't expect such good news today, and he hurriedly asked: "Okay, Mr. Ma!" ”

"Let's go down and prepare, there should be a week for you to prepare, because there is still some equipment on the way that has not been delivered!" After Ma Tian said this, he waved his hand and ended the meeting.

A week later, all the instruments and equipment were in place, and Su Xihua and others also began to follow Ma Tian to build the first prototype.

And Su Xihua and others also began to witness Ma Tian's scientific research ability for the first time, especially Su Xihua was almost on his knees.

I saw that Ma Tian casually dismantled the fuel car, and then introduced them to the principles of various electronic devices one by one, such as the engine, ignition system, throttle controller, etc., and pinched them with ease.

Ma Tian did this on purpose, he wanted to take Su Xihua and others to understand automobile machinery like he took Zheng Shi to meet them.

Not to mention teaching them to be a top automotive engineer, at least they must know how to take charge of the car.

Su Xihua looked at the knowledgeable Ma Tian, and also sighed in his heart that "there is no vanity under the fame", Ma Tian's scientific research ability is definitely the most terrifying one he has ever seen in his academic career, and the hands-on ability and knowledge consolidation are too terrifying!

In the following days, Su Xihua and others became students, wearing shirts with pockets in the front, and carrying a ballpoint pen and a notebook to take notes.

Ma Tian also taught them according to their aptitude, and while talking, he also asked them to dismantle the car to consolidate their knowledge.

After almost two weeks of teaching, Ma Tiancai took them to start building and assembling the body with equipment, mechanical equipment, etc.

First of all, it's definitely the modeling and design of the body.

There are so many things to consider in the production of a car, cost, safety, aerodynamics, etc., are all issues to consider.

Su Xihua and others also knew that what they built was not an ordinary fuel vehicle, but a new energy vehicle with a hybrid of oil and electricity.

After the design is completed, then there are four steps to make a car: punching, welding, coating, and summarizing.

Tu was ignored by Ma Tian, the sample car should not be so bells and whistles, just run with one foot on the accelerator.

A month later, Ma Tiancai led them to build the first automatic transmission new energy vehicle without even a door.

"Mr. Ma, let me test the car first, your body is so precious, how can you be the first to test it?" When Su Xihua heard that Ma Tian was going to be the first to test the car, he hurriedly stopped him, he was worried about the risk.

"Get out of the way, I'll come!" Ma Tian refused.

"Mr. Ma, your precious body, let's take the risk of the first test drive!" Su Xihua insisted.

"Do you suspect that there is a problem with the car we build or do you have doubts about my technology?" Ma Tian frowned and said, this is an automatic car and it has been tested for suspension operation, what risk can it be? He is quite confident in his scientific research level.

Besides, just walk around the park a few times, how could he have an accident on such a wide road and no cars?

Su Xihua didn't dare to stop him when he heard this, but he sat in the co-pilot, and several colleagues who were also building cars together also sat in the back row.

Obviously, with a co-exist mentality.

Ma Tian shook his head and chuckled: "Sit tight!" ”

Then with a foot of the accelerator, the car started up and drove towards the factory road outside.

"Woo-"

After watching the car accelerate and turn easily, several employees in the back row also cheered happily.

The first sample car, almost done!

All that's left is to put the doors, seats, airbags, etc. in place for a vehicle test.

This also shows the difficulty of making physical objects, unlike the Internet to get a server, build a website can be used, there are many things to consider to make physical objects, and the testing required is too much.

Ma Tian called Ji Leiming and Li Runqi over, and they were about to start preparing to build a production workshop and recruit people.

The two of them are also accustomed to seeing the sample car that Ma Tian has developed, and they have become accustomed to Ma Tian's exaggerated research and development capabilities.

Hearing Ma Tian's request to build a production workshop, he also nodded and wrote it down.

Ji Leiming went down to prepare, and Li Runqi looked at Ma Tian to report on the company's situation during this time.

"Brother Ma, the company is running steadily, and there is nothing particularly big.

Oh, by the way, there is one thing that you may need to pay attention to, during your time in retreat, Lei Jun of Rice came to you several times, but I refused on the pretext that you were busy!

However, let me tell you when Lei Jun leaves, you can tell him when you have time, he is coming to visit you! ”

"Lei Jun?" Ma Tian groaned, guessing Lei Jun's intentions, the last time he saw Lei Jun was at the Little Blue Car National Championship, eating offline to discuss the financing of the Little Blue Car.

"He came to me to ask Xia Wei about face recognition and voice assistant on his phone, right?"
