In the laboratory, Liu Yichen was checking the system space, checking his family background, and then looked thoughtful.
In the end, he decided to pursue his career in the battery field. After all, this is the foundation of the Kowloon Era and the foundation for making a fortune. The Kowloon Era is a pillar enterprise in Narcissus City and the key to China's new energy vehicle voice.
.
Once overseas takes the lead in making breakthroughs in new batteries, not to mention surpassing the lithium-sulfur batteries of the Kowloon era, even if the performance is only the same as that of the lithium-sulfur batteries, it will have a huge impact on the Kowloon era.
After all, no one wants to have their core technology mastered by others. If the core technology is no longer in their own hands, they will not feel safe even when they sleep, and they will not have the confidence to speak.
In the past ten years, in terms of innovation and patents in the field of lithium-sulfur batteries, Kowloon Times has accounted for 99% of patent applications, and all core technologies are mastered by Kowloon Times.
However, after nearly ten years of development, the R&D personnel of Jiulong Times have developed the lithium-sulfur battery to the third generation. The theoretical energy density of lithium-sulfur batteries is not far away from 2600Wh/kg. In at least five years, Jiulong Times'
Lithium-sulfur batteries will reach the ceiling of theoretical energy density, and it will no longer be possible to make any difference in energy density. Even if there are some innovations, they will only achieve some small improvements on the original basis, and these are only safety and stability.
Small improvements like that.
Therefore, it is necessary to develop a new generation of batteries.
"Then lithium-air batteries!" Liu Yichen muttered to himself, already having a goal.
Compared with the theoretical energy density of lithium-sulfur batteries, which can reach 2600Wh/kg, the theoretical energy density of lithium-air batteries is as high as 3500Wh/kg.
And when it comes to lithium-air batteries, they are actually not ready enough. To be precise, they should be metal-air batteries, which means that metal is used as the negative electrode and oxygen in the air is used as the positive reactant.
The reason why we call lithium-air battery is that lithium is used as the negative electrode, so the battery performance will be better.
The reaction principle of lithium-air batteries is not complicated. During discharge, metal ions move from the negative electrode to the positive electrode and react with oxygen sucked from the air to generate electricity. During the charging process, the metal ions separate from the oxygen and are separated from the positive electrode.
A reaction that moves to the negative pole.
It can be said that a high school student can understand the principle of reaction.
Lithium-air batteries are not a new thing, on the contrary they have been around for decades.
Since the large-scale production of lithium-sulfur batteries, Kowloon Times has a gold mine of lithium-sulfur batteries. Countries in Europe, the United States, Japan and South Korea are quite unwilling to lose their dominance in the battery field, and have increased the research and development of lithium-air batteries. In recent years, lithium-air batteries
Batteries have become a hot spot in the field of new energy batteries, and some research papers are produced every year.
However, some of these papers are true or false, some have some value, and some have no value at all. Some Japanese companies, European and American companies even claim to have developed lithium-air batteries, but the performance of the lithium-air batteries produced is far inferior to the lithium-sulfur batteries of the Kowloon era.
, and the so-called lithium-air battery has a lot of problems.
There are four big mountains in lithium-air batteries. The first is the stable electrolyte system, the second is the real reaction mechanism of lithium-air batteries, the third is the positive electrode material, and the third is the negative electrode material.
Although countries have burned billions of dollars in scientific research funding in this area in recent years, in Liu Yichen's view, it is actually standing still, with no substantial progress compared to 20 years ago.
How to choose good materials so that they have good ORR/OER dual-functional catalytic performance and catalytic performance for decomposing lithium peroxide; how to ensure that the device itself has extremely low water content. These two difficulties have been solved in scientific research in recent years.
In the paper, no researcher mentions it, they all avoid mentioning it, as if they are trying to save research funds.
Since the launch of lithium-sulfur batteries in the Kowloon era, Japan has failed in hydrogen energy batteries, and a large amount of investment in scientific research has been wasted. However, related companies in Japan are not willing to give up, and have turned to lithium-air batteries. So far, they have invested only a few years.
With more than 2 billion US dollars in scientific research funding, it wants to regain its advantage in lithium-air batteries and gain a say in the lithium battery industry.
This is true in the United States, and it is also true in Europe.
Unfortunately, so far, there has been no eye-catching breakthrough.
Musk recently hyped that Tesla's new energy vehicles would use lithium-air batteries, claiming that the lithium-air batteries in Tesla's new energy vehicles would be the most advanced new energy batteries in the world, causing a stir at home and abroad.
Regarding Tesla's so-called new energy batteries, Liu Yichen was noncommittal, because traditional batteries and traditional lithium batteries were defeated in the face of lithium-sulfur batteries. Lithium-sulfur batteries occupied the mid-to-high-end markets such as mobile phones, computers, and new energy vehicles, and dominated the lithium battery market.
With profits exceeding 90%, most other battery companies have lost the ability to innovate.
As for Tesla's new energy vehicles, it has been difficult to compete with other car giants in recent years. It has not been able to obtain lithium-sulfur batteries. As a result, Tesla's new energy vehicles have a mileage of only 500km and annual sales of less than 1,000 units. Purely.
It’s Musk’s fans who pay the IQ tax to buy it.
Under the intentional or unintentional bias of the Kowloon era, now new energy vehicles are mainly produced by the three main forces of China, Germany, and Japan, and the others are insignificant.
Liu Yichen began to understand the information and then analyzed it, and gradually began to have a clue. If there are problems, it is not scary, just overcome them.
He decomposed the topic into ten research groups, and then began to form the research groups. Among them, the R&D department of Kowloon Times was responsible for six research groups, and Kowloon University was responsible for four research groups. It only took two days to complete ten research groups.
After the formation was completed, research began according to Liu Yichen's requirements.
Liu Yichen himself began to research the most core material, which is a high-permeability oxygen molecule separation membrane used in lithium-air batteries!
Although lithium-air batteries have great potential and are regarded as the next generation of new energy batteries, they are actually a controversial topic in the academic world. There are many people who support it, but there are also many people who question it, and even
It can be said that doubts dominate the mainstream. The most fundamental reason is that lithium metal is extremely reactive and will react with almost all gases in the air except rare gases.
To solve this problem, it is necessary to separate the oxygen in the air and only allow oxygen to enter the reaction system.
The most ideal method is to add a layer of molecular sieve or membrane that only allows oxygen to pass on the surface of the lithium metal or the air inlet of the battery. This seems simple to say, but if you want to do it
Getting to this point is quite difficult.
Liu Yichen wants to develop a high-permeability oxygen molecule separation membrane to solve this problem.
...
At this time, the R&D personnel of the R&D department of Jiulong Times were assigned to form six research groups, and all of them were very excited at this time.
If lithium-sulfur batteries are nuclear fission in the field of lithium electricity, then lithium-air batteries are the same as nuclear fusion in the field of lithium electricity. The idea of obtaining oxides from the outside air basically represents all batteries using lithium metal as the negative electrode material
The upper limit of energy density.
Compared with traditional lithium-ion batteries, the energy density of lithium-sulfur batteries is an order of magnitude higher. Compared with lithium-sulfur batteries, the energy density of lithium-air batteries is also an order of magnitude higher, and whether it is volume energy density or
This is true for mass energy density.
The only shortcoming is probably that it is not suitable for use on devices such as mobile phones or satellites.
After all, the reason why the energy density of lithium-air batteries is high is largely because its oxide is not integrated inside the battery, but is located outside the battery and needs to "breathe".
Mobile phones are often kept in pockets, and satellites are far away from the atmosphere. It is difficult for these devices to take advantage of lithium-air batteries. However, for new energy vehicles or some small fixed-wing drones, there is simply nothing more suitable than this thing.
of energy supply equipment.
It is precisely because of this that lithium-air batteries have more stringent technical requirements than lithium-sulfur batteries.
But the R&D personnel involved in this project were all very excited after signing the confidentiality agreement. It was extremely difficult for them, and no matter how great the difficulty was, they could not stump them, or to be precise, they could not stump the man.
Although Liu Yichen no longer holds an administrative position in Kowloon Times and only retains the title of director, and he does not take the lead many times a year in Kowloon Times, for everyone in Kowloon Times, Liu Yichen, the founder, is actually the founder of Kowloon Times.
The soul of the times, even if Sun Yafang has been in charge of the Kowloon Times for some years, her prestige cannot be compared to Liu Yichen.
They all know that Jiulong Times was founded by Liu Yichen, and the core technology of Jiulong Times was developed by Liu Yichen.
They also all know that the reason why they receive the highest wages in the industry is because of Liu Yichen's philosophy, which allows even the lowest-level front-line employees to work hard and earn an average monthly salary of tens of thousands in a year. Among front-line workers,
There are many people who can get salaries and bonuses of three to four hundred thousand a year.
Technicians like them can get a salary of 250,000 or even 300,000 as soon as they graduate, all because of Liu Yichen.
And they have heard that the company intends to further increase the basic salary and that the employee union's shareholding will increase, and all of this comes from Liu Yichen.
Because as the founder, it would be normal for Liu Yichen not to give shares to any employee. However, Liu Yichen let the labor union hold shares on behalf of employees, so that every employee can enjoy dividends and enjoy the dividends of the company's development.
Now Liu Yichen is going to lead them into lithium-air batteries. As R&D personnel, they understand the prospects of lithium-air batteries. If Jiulong Times masters the core technology of lithium-air batteries, it can be said that Jiulong Times will continue to dominate the battery market for 10 years or even 20 years.
year time.
After so many years of development, Jiulong Times has a very strong R&D team with more than 10,000 R&D personnel. The research team assigned this time, each of the six research groups is led by a professor-level senior engineer.
Even the deputy team leader is a professor-level senior engineer, and the minimum professional title for each team member is senior engineer.
...
At this time, the summer heat in July is the most unbearable. It is the hottest time of the year. The temperature outside is as high as nearly 40 degrees. If you place eggs on the road, they will be cooked within a few minutes. The sea breeze is carrying the heat.
The most comfortable thing in these few months is to be at the beach at night, blowing the sea breeze and drinking coconut.
Everyone is looking forward to it raining soon. Unfortunately, even though it is the rainy season, it is the flood season, but the amount of rain in Fujian Province has dropped significantly this year, and it has not rained for more than half a month.
The Times Headquarters in Kowloon, where 30,000 employees work normally, is also a landmark and iconic building of Narcissus Harbor. The next stop of the Kowloon University MTR Station is the Kowloon Times MTR Station.
In a conference room, the main leadership of the Kowloon Times is holding a meeting. The theme of the meeting is to increase the basic salary and prepare an agreement for the union to increase its shareholding.
"Director Sun, the current minimum wage standard in Shuixian City is 1,700 yuan per month, which is the same level as Ludao and the highest in the province. The current lowest basic salary standard in the company is 4,500 yuan per month. According to our research, considering the past few years
In view of the problems of inflation and currency devaluation, the general willingness of employees is to increase their income by 500 to 1,000 yuan per month on the original basis," said a middle-aged woman.
Wage adjustment is always not a trivial matter, but a major matter.
In the current Kowloon era, there are three production bases and one headquarters, with a total number of employees of 225,000. Even if the increase is 500 yuan per month, an increase of 6,000 yuan per person per year will be equivalent to an additional expenditure of 1.35 billion yuan in wages. If
If the monthly increase is 1,000 yuan, then the increase will be 2.6 billion yuan per year.
However, there has been no change for Sun Yafang, because the profit margin of Kowloon Times is too high, and raising wages is nothing more than transferring part of the corporate tax originally paid to employees.
The meeting continued, and it was naturally not appropriate to give each person an average increase of 500 to 1,000 yuan. Instead, it needed to be increased step by step according to the job level. The basic salary increase standard was finally finalized, which meant that in terms of salary expenditures, Kowloon Times needed to increase the original salary every year.
Basically, an additional 5 billion yuan will be spent.
Then there was an agreement to increase the union's shareholding, which would increase the union's shareholding from the original 20% to 25%. Although it is only a 5% increase, it is not much. In fact, this represents a difference in annual dividends of nearly 10 billion yuan.
Sun Yafang was actually quite emotional. You must know that Liu Yichen used to let the labor union hold 20% of the shares on behalf of employees, which was already very healthy. Looking around the world, there are not many people who can do it. However, she did not expect that at this year's board of directors, Liu Yichen
Chapter completed!
