Chapter 431 Battery Technology

To be able to be the director of a research project in a university, he must not be an old scholar who only knows how to study technology, but must be able to understand interpersonal relationships. Otherwise, how can he raise the money needed for the research? How to enable everyone in the group to perform their duties without internal conflict.

Yuan Jian just wanted to understand this point. In addition, Wang Yi himself was in good condition, rich, educated, and well-known, and he had certain connections, and he was introduced by an old friend, so he came ahead of time. Yi also did not put on airs of an old professor. After asking him about his academic performance and his views on statistics, he smiled and said implicitly that he had a research topic that was almost finished, but there was still A research project on fast charging of batteries is underway, and students with solid basic skills are needed to help.

Wang Yi quickly expressed that he was interested in statistics and admired Professor Yuan very much, hoping to join this research group to study.

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

The rapid charging of batteries is originally a research project strongly supported by the state. Various plans are being researched in various universities, and what Yuan Jian obtained is naturally not the main project, but only related raw materials. Various reaction laws in various environments.

Pick out the obvious ones, calculate the most effective ones mathematically, and let the people in the main project choose them.

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

Accounting computerization undergraduate major, is to learn computer programming, statistics, and auditing.These three subjects 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 subjects of the undergraduate level in the second half of the year, study them thoroughly, and pass the exam well Graduation results, and then logically enter the project team.

Wang Yi knew that Yuan Jian obviously hadn't found a solid clue to the effective use of this battery, otherwise, why would it take a year?
He obediently agreed, and then took the initiative to arrange dinner at Zhuxiang Teahouse, and drove Yuan Jian back to Tingnan University of Technology after dinner.

Then, Wang Yi returned to Fontaine Garden again, logged into Happy Town, opened the library, and carefully browsed through the catalogs of industries that might be related to batteries and energy conversion.

There will be a brief description in these catalogs so that people can decide whether to buy after reading it.

Wang Yi checked one by one. Fortunately, the speed of the network is not so fast. With just a touch of the index finger, the answer comes out. Basically, there is no need to wait, which saves a lot of time.

After spending nearly ten minutes, he finally found the item "Energy Battery" in "Energy Medium", and quickly clicked on it again.

Wow, so many types of batteries!

Without saying anything, I read the introductions one by one.

After another half an hour, Wang Yi finally found a sealed lead-acid battery, alkaline fuel cell and graphene battery that he could understand.

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

People in China now generally use electric two-wheeled vehicles to replace bicycles and motorcycles.

However, this is also suitable for electric two-wheeled vehicles. It is 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 China use alkaline fuel cells, which far exceed lead-acid batteries in terms of charging speed, battery life and power, because some battery life has reached 300 km, the charging speed is about 1 to 2 hours.

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

Not enough, it means that the queue time is prolonged.

Can you imagine having to stand 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 charging limitation that prevents the rapid development of new energy vehicles in China.

Now, basically all project teams researching fuel cells should be trying to solve the 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 the current Huaxia Kingdom, and it took at least 40 minutes to recharge.

Therefore, Wang Yi turned his attention to graphene batteries.

Huaxia is a big producer of graphene, but it is also a big importer of graphene products, which shows that the level of domestic utilization of graphene is really not high.

When he clicked on this directory, he saw that the introduction said that the battery life is 3000 kilometers, it only takes 5 minutes to charge, and it can be recharged up to 3 times.

This is several times better than Huaxia's current graphene battery technology!Wang Yi remembers that he once saw a report saying that the current domestic graphene battery technology has a battery life of 1000 kilometers, and the cycle charging technology is only 3500 times.

Look at the purchase price again, uh, 68 yuan?

Wang Yi's eyeballs suddenly widened.

Damn, such an advanced technology only costs 68 yuan?

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

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

After hanging up the phone, Wang Yi did not hesitate any longer, recharged 68 yuan, and directly purchased this graphene battery technology.

Next semester, you will be my main project!

……

Graphene battery technology, because it is purchased with gold coins, cannot be empowered, and must be learned one class at a time.

There are a total of 200 class hours, and there is also an assessment. Those who fail the assessment cannot finish their studies, and they cannot learn other skills.

It doesn't matter, my powerful Vajra Palm is already at the basic level, and there are few opponents in China at present. I also have an invisible magnetic cannon. 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 three-discipline course integrating materials science, chemistry and kinetics. Power utilization, even if Wang Yi is not majored in materials, chemistry, and kinetics, he can still understand it.

Of course, it is one thing to understand it, but another to fully grasp it.

take it easy.
