Chapter 495: Nanxia Battery

Nanming came back this time, in addition to returning home for the winter vacation, there is another very important reason, that is, the first phase of the battery factory invested by Xia Yiyao has finally been completed, and the preliminary recruitment and training of employees have also been completed. It's time to start work.

Although it was a few years ago, she has long been accustomed to the rapid development of the lazy god system. Xia Yiyao doesn't intend to waste any more time. If she can start work as soon as possible, she will start work as soon as possible.

Anyway, most of the workers are recruited locally, and there is no need to catch up with the Spring Festival travel rush.

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

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

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

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

Nanming found Xu Yafei and said, "Dafei, do you want to make batteries?"

"No!" Xu Yafei shook his head desperately without even thinking about it.

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

It has been more than 100 years since the birth of the battery. Its principle is very simple, that is, to allow the electrolyte to carry charges back and forth between the positive and negative electrodes. Even after so many years, there is no essential change.

The development of batteries is mainly to continuously search for different positive and negative electrode materials, as well as suitable electrolyte solutions. What lead-acid batteries, nickel-metal hydride batteries, and carbon batteries are just different positive and negative electrode materials and different electrolytes.

But in the periodic table of elements, there are only so many elements, and almost all the elements that can be experimented have been tried.

The most popular lithium battery now has a history of 30 years. There are countless people who study batteries, but there are almost no breakthroughs. In 30 years, the capacity of lithium batteries has only doubled. !

What is this concept?

In the past 30 years, the chip performance of the CPU has increased by several orders of magnitude, and it is almost breaking through the sky.

In fact, about batteries, various papers emerge in endlessly, and various theories have also made breakthroughs, such as lithium air, lithium water, and fuel cells. However, few of them can really go out of the laboratory and reach a practical level, Practical, more capable of large-scale industrial manufacturing...

Turning around, but also Nima is a lithium battery!

The experimental chemistry of batteries has two barriers.

One is the laboratory barrier.

A paper was published in the laboratory, and a certain battery can achieve the performance of such and such.

However, in a subject with a particularly high degree of contingency like batteries, there may be dozens of batteries manufactured in the laboratory, and only one has the performance of breaking through the sky, but it will explode with a slight touch...

So the papers are always hype, with various new theories and new batteries appearing, and the number of times doubles, doubles, ten times, and hundreds of times.

But it didn't work.

The second barrier is the production barrier.

If you really want to produce on a large scale, you need to solve the problems of cost, safety, reliability and recyclability.

In any of these areas, if you want to make a small improvement, you need countless experiments.

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

For one experiment, ten or twenty days have passed.

This world is not like a game, there are only a few parameters, and it is enough to traverse it once.

In reality, there are countless factors that affect the experiment. After dozens of experiments, maybe the aspect ratio can only be changed. If tens of billions are thrown in, the effect can only be improved by 10%. This kind of terrifying Subject, who wants to touch?

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

"Then, I'm preparing a paper, will you publish it?" Nan Ming asked again.

"I'll post it! I'll post it!" Xu Yafei quickly turned his head into a chicken pecking rice.

Uncle Ming said that the papers are ready, which means that the whole set of papers is ready, and it must be to usher in a new era, so fools don't publish it.

Therefore, Xu Yafei published several papers on electrochemistry in addition to his own biochemistry. The papers mentioned that magnesium batteries, which are now more popular, 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, in theory, 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 less expensive to mine, which means lower prices. 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 kind of panic when 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, investing in magnesium batteries means completely abandoning the previous 30 years of technology accumulation and mature system of lithium batteries, and completely creating a new system. Not many people have the courage to invest in it , In the international market, magnesium batteries are more like a concept stock, which looks good, but if you really invest in it, you will die.

For Nanxia Battery, this is different.

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

The first batch of products of Nanxia Battery will not be sold to the public. All of them will be supplied to the drones of Lanshen Technology. Users send stronger magnesium batteries for free so they can try them out and advertise.

The ribbon-cutting ceremony of the Nanxia battery took place the morning after Nan Ming came back.

Early in the morning, Wei Rong drove to pick up Nan Ming.

However, Nanming only attended, and did not cut the ribbon on stage. 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 canals and artificial lakes not far away have become The habitat of swans, afraid of frightening the swans, did not even set off a firecracker.

After the ribbon cutting, Xia Yiyao and others accompanied the deputy mayor for a tour, but Gu Gang found an opportunity and ran up to Nan Ming.

Gu Gang said: "Brother Nan, the opening of the battery factory is a bit low-key, why didn't you invite the Lazy God celebration to be lively?"

"Because this is only the first phase of the project." Nan Ming smiled, "The second and third phases are the highlight. Now the magnesium battery is in a transitional stage, and in the future it can only be regarded as a low-end product of Nanxia Battery."

"Low-end products? I heard Mr. Xia say that magnesium batteries have 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 said.

"That's not enough?" Gu Gang stared.

If it wasn't Nan Ming who said this, he must have felt that this person was bragging.

"The energy density of the other batteries we have prepared is at least 10 times..." Nan Ming said quietly.

It's just that these batteries can already be produced by the current production line. From the production line to the production process, they are all brand new, and they will be completed in a while.

"However..." Nan Ming shook his head and said: "The battery is just an evil way, and it is an alternative when there is no choice. We still have to give up the battery after all."

The battery stores electrical energy and then releases it, each process has a huge loss, and the utilization rate of energy is extremely low.

"Give up the battery, what do you use?" Gu Gang stared.

"Nuclear energy..." Nan Ming said quietly.

"Huh?" Gu Gang stared wide-eyed, then smiled, and said, "Brother Nan, you really know how to joke."

Nan Ming shrugged, he was not joking.

"By the way, Brother Nan, you just said that batteries are evil, so what do you think...how about the photovoltaic industry?" Gu Gang asked.

Nan Ming frowned slightly, photovoltaic industry? It refers to Xingda Optoelectronics.

"If the battery industry is evil, then the photovoltaic industry is heresy." Nan Ming shook his head.

"Why do you say that?" Gu Gang was still a little showy at first, but he was stunned when he heard this.

This is the feeling of a basin of cold water being poured down.

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

The photovoltaic industry has been strongly supported by the state since its inception, but even if the photovoltaic industry develops to the extreme, how much energy can it generate?
