Nanming came back this time, in addition to going home during the winter vacation, there is also a very important reason, that is, because the first phase of the battery factory invested by Xia Yiyao has finally been completed, and the preliminary recruitment and training of employees have been prepared, and the construction will officially start.

Although it was a year ago, he had long been accustomed to the rapid development of the lazy god system, and Xia Yiyao did not plan to continue to waste time, and if he could start work early, he would start work early.

Anyway, most of the workers are recruited locally, and they don't need to catch the Spring Festival.

Before the start of construction, there will be a ribbon-cutting ceremony to celebrate the official launch of the production line.

This battery factory was named "Nanxia Battery", and the name was taken from the surnames of Nanming and Xia Yiyao.

As for the products it produces, they are tailor-made by Nanming.

There was once such a conversation about the products produced by Nanxia battery.

Nanming found Xu Yafei and said, "Da Fei, do you want to engage in batteries?"

"Don't!" Xu Yafei didn't think about it, and shook his head desperately.

When he was just learning chemistry, the teacher told him that the battery is a pit, don't jump, whoever jumps will die!

The battery has a history of more than 100 years, and its principle is very simple, that is, the electrolyte carries the charge back and forth between the positive and negative electrodes, and even after so many years, there is no essential change.

The development of batteries is mainly to constantly look for different cathode and anode materials, as well as appropriate ratio of electrolytes, what lead-acid batteries, nickel-metal hydride batteries, carbon batteries, are just different cathode and anode materials and different electrolytes.

But in the periodic table, there are so many elements that almost all of them have been tried.

Now the most popular lithium battery has a history of 30 years, and the number of people studying batteries is inexhaustible, but there is almost no breakthrough. In 30 years, the capacity of lithium batteries has only doubled!

What is this concept?

In the past 30 years, the chip performance of CPUs has increased by several orders of magnitude, and they are almost breaking through the sky.

Actually, about the battery. All kinds of papers emerge in endlessly, and all kinds of theories have breakthroughs, what lithium air, what lithium water, what fuel cells, but there are very few that can really get out of the laboratory and reach the practical level, and those that can be practical and can be made on a large scale of industrial manufacturing......

Spin around. Also Nima is a lithium battery!

And the experimental chemistry of batteries has two barriers.

One is the laboratory barrier.

In the laboratory, a paper is issued, and the battery of such and such can achieve the performance of such and such a person.

But in a discipline such as batteries, which is particularly accidental, there may be dozens of batteries made in the laboratory, and only one of them has the ability to break through the sky, but it can explode at the slightest touch......

So the papers are always in the sky, and there are constantly new theories. When new batteries appear, they increase by one, two, ten, and hundredfold at every turn.

But it didn't work.

The second barrier. It is a barrier to production.

If you really want to mass production, you need to solve the problems of cost, safety, reliability, and circularity.

Any small improvement in any of these areas requires countless experiments.

The ratio of length, width and height of the battery, the ratio of electrolyte, the material, shape and formula of the electrode......

Ten days and twenty days have passed in one test.

The world doesn't feel like a game. There are only a few parameters, just iterate over them.

In reality, there are countless factors that affect experiments, and dozens or hundreds of experiments may only have to change the aspect ratio. Tens of billions of dollars smashed into it can only increase the effect by 10%, this kind of terrifying discipline, who wants to touch?

Xu Yafei doesn't want to become an experimental migrant worker......

"Then, I'm going to prepare a paper, will you send it?" Nan Ming asked again.

"I'll send it! I'll send it!" Xu Yafei hurriedly nodded his head into a chicken pecking rice.

Uncle Ming said that the papers are ready, that is, the full set of papers are ready, and it must be to create a new era, and the fool will not send it.

So, in addition to his own biochemistry, Xu Yafei came to several electrochemical papers, which mentioned magnesium batteries, which are now more popular and can replace lithium batteries.

The magnesium battery is the product prepared by Nanming for the first phase of the Nanxia battery project.

The benefits of magnesium batteries are, first, theoretically speaking, the capacity of magnesium batteries is at least twice that of lithium batteries. Second, as long as the production line of lithium batteries is slightly modified, it can be produced. Third, magnesium is cheaper to mine, i.e., cheaper. Fourth, the emergence of magnesium batteries is not a big leap for Nanming, and it will not cause excessive panic in the entire industry.

In fact, it was a panic that magnesium batteries really began to be put into the market on a large scale.

Although many people think that magnesium batteries are the next generation of batteries, but to invest in magnesium batteries, that is, to completely abandon the previous lithium battery 30 years of technology accumulation and mature system, completely create a new system, not many people can have the courage to invest in it, in the international market, magnesium batteries are more like a concept stock, looks good, but really put into it, will die.

For Nanxia batteries, this is different.

Nanming's "secondary strengthening" ability, the most ungodly place is that it can strengthen knowledge, the technical system of magnesium batteries, he has already prepared, and he has secretly trained the technical backbone, just waiting for the official launch.

The first batch of products of Nanxia battery, not for sale, all supplied to lazy technology drones, after the first batch of products off the assembly line, lazy technology will send a stronger magnesium battery to all the first batch of lazy technology drone users for free, let them try, but also advertising.

The ribbon-cutting ceremony of the Nanxia battery was held on the morning of the second day after the return of the Southern Summer.

Early in the morning, Wei Rong drove a car to pick up Nanming.

Nanxia Battery Factory invited a deputy mayor in charge of industry in the city to cut the ribbon with Gu Gang and Xia Yiyao, because the canal and artificial lake not far away have become the habitat of swans, and they are afraid of frightening the swans, so they didn't even set off firecrackers.

After cutting the ribbon, Xia Yiyao and others accompanied the deputy mayor to visit the circle, but Gu Gang found an opportunity and ran in front of Nanming.

Gu Gang said: "Brother Nan, the opening of the battery factory this time is a bit low-key, why didn't you bring the lazy god celebration to be lively?"

"Because this is only the first phase of the project. Nanming smiled, "The second and third phases of the project are the main event, and now the magnesium battery is a transitional stage, and it can only be regarded as a low-end product of Nanxia battery in the future." ”

"I heard Mr. Xia say that magnesium batteries are at least twice the energy density of lithium batteries. ”

"According to different production processes and models, our current battery products should be 2 times, 3 times and 5 times the capacity of lithium batteries of the same size. "Nan Ming Dao.

"That's not good?" Gu Gang glared.

If it wasn't Nan Ming who said this, he would definitely think that this person was bragging.

"The energy density of the other batteries we have prepared is at least 10 times ......," Nan Yin Yu said.

It's just that these batteries can be produced by the current production line from time to time, from the production line to the production process, they are all new, and they will be completed from time to time.

"But ......" Nan Ming shook his head, "The battery is just an evil way, an alternative in situations where there is no choice." We're going to have to give up on batteries after all. ”

Batteries store electrical energy and then release it, and each process has great losses and extremely low energy utilization.

"Give up the battery, then what do you use?" Gu Gang's eyes widened.

"Nuclear energy ......" the South Shadow Path.

"Huh?" Gu Gang's eyes widened, then he smiled and said, "Brother Nan, you are really joking." ”

Nan Ming shrugged, he wasn't joking.

"By the way, Brother Nan, you just said that the battery is an evil way, so what do you think...... How about the photovoltaic industry?" asked Gu Gang.

Nanming frowned slightly, the photovoltaic industry refers to Xingda Optoelectronics.

"If the battery industry is heretical, then the photovoltaic industry is heresy. Nanming shook his head.

"Why do you say that?" Gu Gang originally had some tricks, but he was stunned when he heard this.

It's the feeling of a basin of cool water splashing.

"The most basic reason is that the unit density of surface solar energy is too low. "Nan Ming Dao.

Since its birth, the photovoltaic industry has been vigorously supported by the state, but even if the photovoltaic industry develops to the extreme, how much energy can it produce? )

PS: That's all there is to it today, tomorrow morning on the train at six o'clock, Uncle Ha is going to sleep.
