If you can be the host of a research project in a university, you must not be an old scholar who only knows how to study technology, but must be able to communicate with each other, otherwise, how can he raise the money needed for research, and how can everyone in the group be able to perform their own duties and not be inward-looking.

Yuan Jian just figured this out, plus Wang Yi's own conditions are good, rich, After asking about his academic performance and his views on statistics, he smiled and implicitly said that he currently has a research project that is almost finished, but there is also a research topic on battery fast charging that is ongoing, and students with solid basic skills are needed to help.

Wang Yi hurriedly expressed his interest in statistics, admired Professor Yuan, and hoped to join this research group to study and study.

After all, he was only a senior in the second half of the year, so there was no need to rush into the research project that was almost finished, and share the credit and profits, it was better to join the second topic.

The fast charging of the battery is also a research project that the state is currently strongly supporting, and all kinds of schemes are being studied in various universities, and what the original sword has gotten is naturally not the main project, but only the various reaction laws of raw materials in various environments.

Pick out the obvious ones, and then use the mathematical way to calculate the most effective, and take them out for the people in the main project to choose, just fine.

Wang Yi believes that such a research topic is definitely not the main project in the hands of Professor Yuan, and he should have many other research projects, but this one is something that Wang Yi can participate in.

The undergraduate major in accounting computerization is to learn computer programming, statistics, and auditing. These three doors are actually dealing with numbers and finding patterns from them.

Yuan Jian was really happy with Wang Yi's choice, nodded with a smile, and promised to show him the corresponding mathematics textbooks first, so that he could study the various disciplines in the undergraduate section in the second half of the year, study them thoroughly, get a good graduation score, and then enter the project team logically.

Wang Yi knew that for the effective use of this battery, Yuan Jian obviously had not found a practical clue, otherwise, why would it take a year?

He obediently agreed, and then took the initiative to arrange dinner at the Zhuxiang Teahouse, and drove Yuan Jian back to Tingnan University of Technology after dinner.

Then, Wang Yi returned to Fontaine Garden again, logged in to Happy Town, clicked on the library, and carefully browsed the catalogs that might be related to batteries and energy conversion in the industrial catalog.

These catalogs will have a brief description so that people can read it and decide whether to buy it or not.

Wang Yi checked them one by one, and was very glad that the speed of the network was not ordinarily fast, and with a little index finger, the answer would come out, basically without waiting, and it would save a lot of time.

It took nearly ten minutes for him to finally find the "energy battery" item in the "energy medium", and quickly clicked on it again.

Wow, there are so many types of batteries!

What I didn't say, I looked at the introduction one by one.

It took another half an hour for Wang Yi to finally find the sealed lead-acid battery, alkaline fuel cell and graphite thin battery that he could understand.

He first looked at the sealed lead-acid battery, which is also the battery commonly used in current electric vehicles, which takes six hours to charge and has a range of about 80 kilometers.

This electric two-wheeled vehicle is now widely used by people in Huaxia to replace the bicycles and motorcycles of the past.

However, this is also suitable for electric two-wheeled vehicles, which are not enough for new energy vehicles that require faster speed, higher battery life and higher charging speed.

Most of the electric vehicles on the market in Huaxia use alkaline fuel cells, which far exceed lead-acid batteries in terms of charging speed, endurance and power, because some have a range of 300 kilometers and a charging speed of about 1 to 2 hours.

However, this requires dedicated charging piles, and there are not enough chargers on the highway.

Not enough, it means longer queues.

Can you imagine having to wait in line for two or three hours on the highway to recharge?

It only takes 10 minutes to refuel a fuel car.

It is this limitation of charging that makes new energy vehicles unable to develop rapidly in Huaxia.

Now, basically all the project teams working on fuel cells should be trying to solve this problem of too long charging time.

Wang Yi looked at the introduction of this fuel cell and found that its performance was not much better than that of Huaxia now, and the time to charge it again was at least 40 minutes.

So, Wang Yi turned his attention to graphite thin batteries.

Huaxia is a major producer of graphite, but it is also a major importer of graphite products, indicating that the domestic level of utilization of graphite is really not high.

He clicked on this directory and saw that the introduction said that the battery life is 3,000 kilometers, it only takes 5 minutes to charge, and it can be recharged up to 30,000 times.

Wang Yi remembers that he once saw a report that the current graphite thin battery technology in China has a range of 1,000 kilometers and only 3,500 cycles.

Look at the purchase price again, uh, 680,000 yuan?

Wang Yi's eyes widened.

Damn, such advanced technology, it only costs 680,000 yuan?

Wang Yizheng wanted to buy it, but suddenly stopped, thought for a while, and dialed Yuan Jian's mobile phone: "Hello Professor Yuan, I want to ask, is your battery research project related to graphite?"

When a positive reply came from the mobile phone, and the research direction was the number of cycle charges, Wang Yi swallowed his saliva and immediately expressed his interest.

After hanging up the phone, Wang Yi did not hesitate any longer, recharged 680,000 yuan, and directly purchased this graphite thin battery technology.

Next semester, you'll be my main project!

……

The technology of graphite thin batteries, because it is purchased with gold coins, cannot be initiated, and must be learned class by class.

A total of 200 class hours, there is also an assessment, and those who fail to meet the assessment cannot end their studies, and they cannot learn other skills.

It doesn't matter, my current powerful Vajra palm is already at the basic level, and there are few opponents in the country at present, and I also have an invisible magnetic canon, and I am not afraid of force.

He quickly threw himself into his studies.

Soon, Wang Yi was pleasantly surprised to find that this course is a course that integrates three disciplines: materials science, chemistry and kinetics, and explains in simple terms the material characteristics of graphite dilute, as well as the resulting material use, chemical reaction and power utilization, even if Wang Yi is not a material and chemistry, and kinetics three majors, he can still understand.

Of course, it's one thing to understand it, it's another thing to master it thoroughly.

Take your time.
