For the gift, start research and development of graphene batteries

Chapter 7 Project Meeting

The speaker didn't mean it, but the listener meant it. Hearing Jiang Ming say that it was caused by the side effects of the medicine, everyone was convinced that Jiang Ming had a serious illness.

And to a large extent, it is a mental illness. You must know that a mental illness is serious, and it is very aggressive when it flares up.

After being identified as a mental disorder, even if a crime is committed, there is no need to be responsible.Everyone wisely didn't provoke Jiang Ming. After all, whoever meets him will be unlucky.

"Oh, then take care of your body."

After the girl named Liu Rui finished speaking, she hurried to her station, not daring to look at Jiang Ming again.

Jiang Ming laughed at himself for a while. He didn't think that with his image, he could go out and scare people, which was a bit funny.

Jiang Ming was also helpless. He thought that his thin face would get better after a night of rest, but he didn't expect it to get worse.

It was an ordinary face, but under the blessing of gray and thin, to be honest, it was a bit scary.

Jiang Ming was thinking about whether he should go to the hospital to have a look if he still looks like this after a while.

Now, let it be like this, after all, I just came out of the hospital, according to the current situation, the impact is not very big, otherwise the doctor would not let me out of the hospital.

After the hustle and bustle just now, the office became quiet, and everyone was busy preparing for a day's work.

Jiang Ming sat at the work station, did not turn on the computer, but took a notebook and recorded something in it.

In fact, it is not as easy as Jiang Ming imagined to develop graphene batteries.

There are too many steps that need to be improved, and if one is not good, it will easily cause the battery to be scrapped.

Of course, in terms of broad categories, the components of lithium-ion batteries only fall into those categories.

Generally speaking, lithium-ion batteries are mainly: positive electrode, negative electrode, electrolyte, separator and casing.

Of course, within these major categories, there are many subcategories, which actually contain a lot of material.

The quality of these materials is related to the quality of the finished battery.

Of course, this involves the issue of the process technology affecting the yield rate, which is not what Jiang Ming, a research and development engineer, should do.

The responsibility of R&D engineers is to design a set of feasible solutions, at least theoretically feasible, and feasible in practice.

This is difficult to say, but also simple to say.

Now that Jiang Ming knows that graphene batteries are feasible and the technical solution is no problem, for Jiang Ming, the difficulty is naturally reduced a lot.

Even though the difficulty has been reduced a lot, it is still difficult to design it.

Especially the technology of this era is incomparable with the technology in the technology tree. Even if Jiang Ming can think of a lot of equipment and materials, he can't make them.

This required Jiang Ming to be able to make some changes.

If there are too many changes, the effect will not be achieved, and if there are too few changes, it will not be possible to achieve it. This is also a headache.

Thinking of this, Jiang Ming got a little dizzy. This involves a lot of verification work, and he would not be exhausted by himself alone.

Thinking of this, Jiang Ming felt that he had to think of a way.

At the same time, in order to reduce the workload, Jiang Ming thought it would be better to implement his plan in batches.

Jiang Ming didn't plan to upgrade ordinary lithium batteries to graphene batteries all at once, but only designed a plan for this project bonus.

A complete graphene battery is a subversive product. Compared with the mission goal, the upper limit is too high and completely unnecessary.

Various thoughts circulated in Jiang Ming's mind, and finally locked on one direction: negative electrode materials.

According to Jiang Ming's calculation, as long as the negative electrode material is improved, the company's energy density requirements will be met.

Of course, raising the upper limit of a single material may cause some problems. Jiang Ming is confident that he can solve these problems under the current conditions.

Afterwards, Jiang Ming wrote again in his notebook.

The tranquility of the office was broken not long after, and everyone was notified to go to the conference room for a meeting.

As for the topic of the meeting, Jiang Ming knew it without guessing.

In the conference room, R&D Department [-], all the cell R&D engineers are in place.

Right in front of the meeting, Li Ming, the supervisor, announced to everyone the company's strategic project: a lithium-ion battery with an energy density of 500Wh/kg.

Everyone seemed to be very clear about the content to be discussed in today's meeting, and they expressed their suggestions one after another.

A: 500Wh/kg, this is a great challenge for the industry. As far as I know, the leading companies in the industry have entered the substantive verification stage, and I believe they will make samples soon.I believe that we too will soon succeed.

Jiang Ming looked at Engineer A and was a little speechless. He only knew how to shout slogans and show off his qualifications, but you offered some substantive suggestions.

Now that you have the ability to know that your competitors have entered the substantive verification stage, can you please share the technical solution, let us refer to it!

B: I agree with A's opinion, but it is really necessary to speed up the progress, otherwise there will not be many market opportunities.

Jiang Ming: Another follower, you are a research and development engineer, why did you mention the market issue here? Is this an issue you care about?
Next, everyone expressed their opinions one after another, some were 'inspiring', some were 'cynical', and some were 'discouraged'.

All kinds of opinions are different, but it is also very lively.

However, most engineers are still interested. After all, this is a company-level project. If they can make some achievements, it will greatly promote their promotion and salary.

Who said that R&D engineers are a group of guys who only know about research and don't know how to understand the world, and they are not more active than the group of marketing people?

But after discussing for a long time, there was no substantive plan. Most people just stayed on their lips, but they didn't see the specific technical plan.

In other words, most engineers are unwilling to disclose their technical solutions.

After listening for a long time, Jiang Ming understood a little bit.

This technical problem is indeed too difficult for their company. You must know that the current energy density of their batteries has just reached 220Wh/kg. It is almost impossible to double it in a short period of time. .

Since we know that we can't finish it, we are still discussing it endlessly, which is a bit intriguing.

After thinking about it for a while, Jiang Ming understood everyone's thoughts. This was a company-level R&D project, and no one wanted to give up.

I know that I can't finish it, but if I can do better than others, and I can pull out the general in the slump, I will always be rewarded.

Of course, you have to jump higher than others!
After discussing for nearly an hour, everyone's opinions gradually became somewhat unified.
