Chapter 91 The reform of the new energy industry is imperative, graphene-sulfur-lithium-air battery

After Su Sheng and Teresa finished chatting, he said to the three of Fu Te: "This year, Rongguang College is not going to enroll students. I applied for Rongguang College to be a special university education university. Therefore, every June, we will recruit new students and organize an admission Special assessment, reference students are not limited to all factors such as age, region, school, etc. The content of the assessment is up to you to decide. Glory College wants geniuses, real geniuses, not high test scores. Therefore, the three need to wait for one year. , I will apply for a physics research institute for three professors, and you don’t have to stay in a closed virtual laboratory all day.”

Turning to Terrela, he said, "Professor Terrela is the same. You can go to cooperate with Professor Bullock to develop new energy technology and new power engine technology. When you need to develop security technology, you can come to the virtual laboratory."

The four of Volt and Teresa nodded and nodded.

……

The next day, the start of school, reporting and registration, after the class meeting, the dormitory returned to its previous appearance. The bully Gou Fugui studied in the library during the day, and video chatted with his "little cousin" at night, chatting one after another, flirting one after another. While the other two are busy with school club activities all day long, he is more leisurely.

After visiting Teacher Li Heng, Su Sheng went directly to the instructor to ask for leave, "Director Sun, please take half a month, I have private matters to attend to."

"No!"

Sun Yu is 27 or [-] years old, with upper-middle appearance, native of Handong, graduated from Nantah University with a master's degree in psychology, and has been in the school for the third year. She speaks extremely aggressively. More than [-] monks majoring in mechanical and electrical engineering are trembling and cautious under her majesty. , Life feels like years, there is no way, the credits are held tightly by her!
"Director Sun, here you are."

"Principal's approval? Su Cheng, you have a lot of energy."

Wherever the Rongguang Technology signboard was placed, the principal smiled and signed the signature happily. After all, soon the name "Su Sheng" will be hung on the honor column of famous alumni of Hangzhou University. Su Sheng is the pride of Hangzhou University. , the glorious image and golden brand of Hangzhou University, so face must be given.

"Haha, it's not worth mentioning."

Sun Yu put the leave approval form aside, "The principal approves it, and I have no right to deny it, but I hope that as a member of the 17th grade mechanical and electrical department, you can do me a favor and win glory for the profession!"

"Tell me what? What do you need me to do?" Su Sheng felt the difference.

"The red-letter document requires contemporary college students to actively participate in the upsurge of founding new technology companies in the context of the new era, and contribute to the development of China's technology and economy, and you, I think it is suitable, you can participate as a representative of our school. "

After Sun Yu learned about Su Sheng's identity from the principal, she naturally understood the reason why Su Sheng asked for leave frequently and led the class to bring out a rich man. Although she was deeply moved, as a counselor, as long as Su Sheng was in school for one day, she would be her student.

"but I……"

"Don't refuse in a hurry. The issue of the red-letter document this time is related to you. I have reported to the principal that you are the most suitable."

"It's about me?"

"Your glory has awakened the enthusiasm for science and technology among the people. Start a business with science and technology. In March, you entered the ranks of unicorns and set off a wave of high-tech technology. The above meaning is probably to strike while the iron is hot and develop the science and technology economy. First, to strengthen the country with science and technology, and second, to promote the economy. Prosperity and development will increase employment and entrepreneurial opportunities and positions for college students, as you know, the employment of college students is the most troublesome problem for schools and higher-level leaders during the graduation season every year."

Su Sheng smiled and said, "Do you want me to take part in the competition with glory? Then let the judges award the championship trophy to us directly."

"...Ahem, you can, um, just let your team develop a new technology, okay?"

Sun Yu almost agreed when Su Sheng said it, but he had to hold back, joking, using glory to participate in the competition, isn't it the same as an adult bullying a baby?

"Let me think about it..."

"Su Sheng, let me tell you, don't hesitate, the support for this competition from above is very strong. The organizer is jointly organized by the Beijing General Science and Technology Department, the Ministry of Industry and Information Technology, and the Ministry of Education. The first three awards will be issued with a private science and technology license. You should Know what it means!"

The science and technology license is equivalent to the license of a state-owned technology enterprise. It does not need the jurisdiction of the local science and technology, industry and information technology departments, and taxation departments. It is less deterrent than the Gyeonggi license of Rongguang Chip.

"Moreover, it can be exempted from corporate tax for five years!"

Su Sheng's eyes lit up, "What Director Sun said is true?" For him, tax exemption is more tempting than a science and engineering license.

"The red-lettered document has the official seals of the three ministries of science and technology, industry and information technology, and education. It is impossible to falsify, let alone not keep what you say!"

"Okay, please help me sign up, Director Sun."

"After thinking about the direction of starting a business and registering the company name, please contact me."

Su Sheng shook his head, "Don't wait, just now, the direction of the business is the new energy & power industry, in other words, car companies! And the name of the company is Tela & Block Group, referred to as Tebu Group."

Sun Yu: "..."

"New energy? Cars, car companies? Su Sheng, are you kidding me?"

"No kidding, just sign up for me."

After finishing speaking, Su Cheng bid farewell and left, while Sun Yu was completely unwell!Car companies? !Is anyone in a car company capable of doing it?
Huge capital flow pillar, high-precision machine tool assembly line, top elite scientific research talents...

However, Sun Yu suddenly realized that Su Sheng seemed to be able to do it!Want money?Glory is making money every day; important people are waiting for a strong scientific research team; equipment is needed...if you have money, you can talk about any kind of equipment.

Expectation!

……

After Su Sheng took Tela to Rongguang Science and Technology Laboratory, he introduced Professor Tela to everyone.

"Terra, you should be familiar with it, and we will add another member to the Rongguang scientific research team in the future."

Tela took the initiative to get acquainted with everyone. Half an hour later, Bullock reported the progress of the new energy project, "The development of the graphene battery technology system. At present, the first graphene battery technology is graphene-sulfur-lithium-air battery! Consumption The conversion rate is 0.02%, and the conversion rate is 99.97%. The fast charging technology has been discussed with Professor Volt, Professor Ampere, Professor Ohm and Mr. Chang Gung. The speed rate can be reduced by more than 80%, which can be reduced to less than half an hour, but it is 10% away from our research and development goal. Minutes, still has a large distance."

Su Sheng was a little unfamiliar with words such as loss and transformation, and he didn't know the specific performance indicators, so he asked: "What are the current performance parameters of the vehicle batteries in our classified projects? How is it compared to the current batteries?"

Bullock explained with an example: "There are currently five main types of new energy batteries for vehicles, namely lead-acid batteries, nickel-cadmium and nickel-lead batteries, lithium batteries, lithium iron phosphate batteries and fuel cells. However, these batteries themselves have their own disadvantages and shortcomings.

For example, lead-acid batteries, although low in cost, mature in technology, and mass-produced, have very low specific energy, specific power, and energy density.

Nickel-cadmium batteries and nickel-lead batteries are more environmentally polluting, but their performance is better than that of lead-acid batteries, and they are energy-efficient, so half of the mainstream market currently uses them.

Lithium batteries have the advantages of high voltage and high specific power up to 165W h/kg, more than three times that of nickel-hydrogen batteries, small size, light weight, high cycle times, and no pollution, but unfortunately their safety performance is poor. For example, traditional batteries are greatly affected by the environment.

For example, lithium iron phosphate batteries are inferior to lithium cobalt oxide batteries in terms of energy, but they have high safety performance, low cost, and can be cycled more than 2k times.

As for fuel cells, although they can be recycled permanently, their conversion rate is too low and they are not widely used.

It can be said that the specific performance parameters of the common batteries on the market of the above species fluctuate between 50Ah and 150Ah in stock, and their specific energy range is large, the lowest can reach 30W h/kg, and the highest can reach 960W h/kg. The discharge current density is average It can reach 60-550mA/mm2, the number of cycles is about 600-3000, and the mileage is about 200-1500Km.

The charging method is AC and DC. The domestic charging time ranges from 5 to 10 hours. The foreign energy battery technology is better, and it still takes 3 to 8 hours. If you add a battery pack, it will increase the storage current in the fast charging mode. In order to achieve the fast charging mode in a short time, the continuous battery life is short! "

Su Sheng can understand this point, which is probably like the mobile phone manufacturer's advertisement in the previous life that said "charging for 2 minutes, talking for two hours".

Block went on to say: "Our battery technology, graphene-sulfur-lithium-air battery, has overall technical parameters and performance parameter ratios that are three to five times higher than all new energy vehicle batteries in the market, and is not affected by harsh environmental factors. , the maximum number of cycles can reach more than 5000 times, but I am not satisfied with the fast charging technology, and it will take half an hour to fully charge."

Su Sheng: "..."

People need 5-10 hours or 3-8 hours to fully charge, but you are not satisfied with the old half-hour charge?As expected of a "perfectionist" Brock!
With this battery on the side, once it comes out, the reform of the new energy industry is imperative!
