I kidnapped an alien civilization

"Boss, what are you thinking?" Xia Qing asked with concern seeing his brows furrowed.

Li Mo manipulated the vehicle more than a truck. The handling of this car was very good, and it was more comfortable than all the oil trucks he had driven before, and the power was available at any time. Also, because of the direct output of electricity, the throttle response speed of the electric motor beats all diesel locomotives. And compared with gasoline engines, electric motors have a simple structure, low cost per unit power, no complicated pipeline design, no need for engine oil, air filter, and steam filter, and maintenance is easy and cheap.

The only downside, and the biggest one, is battery life and charging.

Li Mo slowly made up his mind that he must invent a car battery that can solve these two problems.

He said: "If there is a new energy vehicle with a battery life of 1,500 kilometers and a charging time of only 10 minutes, do you think it will sell well?"

Da Fei said, "If there is such a car, it will be a big hit, it will be a hit. You can already feel how cool an electric car is."

"Every time after driving a new energy vehicle, my Ferrari feels that the acceleration is too slow."

"It's a pity that the battery life is not enough. Every time you travel, you need to plan your route in advance and choose those service areas with fast charging stations."

"In case, the fast charge in the server doesn't work, then you're blind."

"It was the first time I drove a new energy car for a long distance. I didn't pay attention to the battery. In the end, I had to sleep in the car and wait for the charging car."

Da Fei curled his lips, the feeling was not good.

Li Mo nodded.

He gave directions, and the car stopped by the side of the road.

Looking back, he smiled and asked Da Fei, "Can we visit the new energy vehicle factory?"

Da Fei was startled, "Boss, do you have any new ideas?"

Li Mo shook his head, "I'm just a little interested, and it's best to be accompanied by an engineer." He has no clue about batteries at present, and he may have new ideas after learning about the whole process of battery production.

Da Fei reluctantly took out his mobile phone and dialed a number, "Hello, brother, I'm Da Fei, and I have a friend who wants to visit your factory."

"Yes, an engineer is also required to accompany you."

Maybe there was some request from the other side, Da Fei said impatiently: "Understood, am I applying according to the procedure?"

After hanging up the phone, Da Fei said: "My brother will make arrangements, but we need to sign a non-disclosure agreement before entering."

Li Mo nodded, Dafei has many buddies, and it is normal to enter the core area of ​​the factory to sign a confidentiality agreement.

Inside a new energy vehicle factory

The whole row of new energy vehicles parked in the parking lot looks gleaming under the sunlight.

"I'm Gong Wang, an engineer in the battery laboratory." A middle-aged man in overalls stretched out his hands from afar.

Although his face was full of smiles, his feet did not move, and his eyes looked away from time to time.

"Hello, I'm Li Mo, thank you for your company." Li Mo could see that Wang Gong was obviously in a bad mood, and seemed to have some resistance to this small task.

I think so, people who are really technical people always have a full schedule, and most of them are unwilling to accept this kind of administrative tasks. Especially leading "several children" to visit the factory.

"I don't know what you want to visit here. Our production line is one of the best in the country. It adopts fully automated production. Why don't I take you to visit it?" Wang Gong asked.

The purpose of Li Mo's visit this time is not to see how the car is made, what he needs most is to find some "new battery" ideas.

Li Mo thought for a while and replied: "There is no need to visit the assembly line. I mainly want to visit your battery laboratory."

"Da Fei, you don't have to stay with me."

He saw Da Fei looking around and knew that Da Fei was not interested in these things.

Da Fei was overjoyed when he heard the words: "Then I'll go find my buddies, call me when you're done."

Watching Da Fei leave, Wang Gong hesitated and said, "Our factory management is very strict, your friend just left like this, is it okay?"

Li Mo smiled and said: "It's okay, there are his buddies here."

There is a "buddy" who allows them to visit the factory directly and is accompanied by an engineer. I think they will not encounter any problems when they come to Dafei.

"Are you sure you want to visit the battery laboratory? It's very boring there, not as advanced as the vehicle manufacturing workshop." Wang Gong confirmed again.

Li Mo nodded, "By the way, explain to me the batteries you are currently using. I am very interested in this."

Wang Gong showed a surprised expression. He didn't expect that the young man in front of him would be interested in batteries. Ordinary people would only like the stylish appearance and beautiful crystal dashboard.

He thought for a while and asked, "Do you know the principle of the battery?"

Hearing Wang Gong in front of him questioning in the tone of a teacher, Li Mo replied: "The basic principle of the battery is to use "higher activity" metal materials to make the anode, and use relatively stable materials to make the cathode. The reason is that electrons are lost and flow to the cathode to gain electrons, while inside the battery, the anions of the cathode flow to the anode to combine with the cations, thus forming a circuit and generating electricity."

"It can convert the absorbed electrical energy into chemical energy and store it, just like a warehouse. Charging is storing electrical energy in the warehouse, and discharging is transporting electrical energy out of the warehouse."

Wang Gong nodded involuntarily, put away some underestimating mentality, and the answer of the young boy in front of him was very standard. In particular, the "warehouse" metaphor at the back accurately describes the characteristics and functions of the battery.

"Currently, batteries commonly used in electric vehicles include nickel-metal hydride batteries, lithium iron phosphate, and ternary lithium."

"We use a special lithium iron phosphate battery, do you know why?"

He asked another question, and Li Mo shook his head.

"These three types of batteries have their own advantages and disadvantages. Ni-MH batteries have a very good memory, and they can remember clearly when they are overcharged or discharged, and then the power will decay. Therefore, Ni-MH batteries have high requirements for charging and discharging time, and the power must be maintained. It is within a fixed range, so it is generally used in hybrid models."

"The ternary lithium has the largest power, but it has an obvious disadvantage, that is, it has strict requirements on heat dissipation. For safety, each battery must have a safety device. Even if the heat dissipation is in place, once a collision or short circuit occurs, the three Lithium-ion batteries may also catch fire and spontaneous combustion."

"There is also the lithium iron phosphate battery we use. Although the power of the same weight is not as good as that of the ternary lithium battery, it has good thermal stability and is not easy to catch fire. The cost of heat dissipation parts is much lower."

Cars are a means of travel that people often use, and safety must be the first priority. Li Mo thinks the choice of this new energy vehicle is wise.
