Chapter 783 Who invested lithium batteries ...

From the beginning, the plan of the mobile phone was supported by the Pentagon, but now the mobile phones are still a little distance from their expectations, so so far, the Pentagon has not adopted a mobile phone for battlefield communication.

Catherine also believes that this plan is unreliable, but since the Pentagon wants to give him money, it is always impossible for himself to do not want it?

If you have money to not earn, it is Wangba egg, Catherine is inappropriate to be Wangba egg.

Especially in the aspect of the pentagon.

However, the bottleneck of the research of mobile phones is not because of the mobile phone itself, but because of the mobile phone's circuit and the battery of the mobile phone. If the volume of the current circuit can be reduced by 80, the current mobile phone can be said to be the best.

, But limited to technology, there is no way to shrink the mobile phone at all.

And the problem of another battery is also a Catherine headache. Even if you cannot reduce the mobile phone circuit, if you can take out the lithium battery of later generations, the body size of the mobile phone can be reduced by a quarter of the current mobile phone. The weight is even more important.

It will greatly decrease.

The ideal is plump, and the reality is skinny. If Catherine can projected her thoughts, she doesn't have to stay in the office now.

"It seems that you can only come step by step ..."

Catherine scratched her head.

The basic is just a mobile phone that requires the function of calling. It can be said that it can be said to be simpler.

The simplest mobile phone consists of four circuits, that is, transmitting circuit, mixing circuit, DSP circuit and power circuit.

Such a simple mobile phone, even a college student at school, is not very difficult to design.

The so -called DSP circuit is the signal processing circuit.

The use of SFC now to process information is to play such a role.

For a rough estimate, Catherine found that if it is replaced with a special circuit, the mobile phone can save about 30 power consumption.

At the beginning of the power consumption, Catherine has achieved the extreme, so it is impossible to save power for the time being.

For the development of dedicated chips, Catherine directly passs Intel to design and research. Now there are no more than ten manufacturers in this world who have enough ability to study such micro -processing chips.

It's.

Then, the battery is.

Catherine asked the people below to check the news about lithium batteries.

Perhaps this thing is too rare. Catherine has been waiting for three weeks. It was not until mid -February that the news was obtained: Akson developed a lithium battery a year ago!

The experts of Exxon use titanium sulfide as the positive electrode material and metal lithium as the negative electrode material to make the first lithium battery in this world!

When he heard this news, Catherine wanted to hit his head.

Exxon.

In other words, exxonmobil.

That is Ex SenMobil.

Catherine never expected that the first lithium battery in the world was actually such a petroleum giant ... What is this?

"Now some companies like to do blindly. They are obviously a company that is oil, but what battery is going to do ..."

After seeing the report, Catherine couldn't help but say a word, while Elsa looked at Catherine with strange eyes.

"Why look at me like this?"

Catherine froze.

"Because I think in this regard, you do better than the other party."

But there is nothing to read this sentence, but combined with the above sentence, this sentence is not so nice ...

"Well, as long as you can make money." Catherine turned her eyes and put her eyes on the ceiling.

Catherine feels bad, in fact, it is not because the other party has a lithium battery, it is just because the news of "developing a lithium battery is Exxon" made Catherine feel depressed.

If it is another small company, Catherine does not need to be troublesome, just buy the other party directly, but ExxonMobil ... Speaking of them, even if they want to buy themselves, they can get that money ...

Of course, Catherine will never sell his own company.

In the 1970s, there were very few news about lithium batteries, and Catherine knew fewer. Now this news is obtained. Catherine seems to have caught a life -saving straw and will not give up easily, so Catherine at this time

What I think about is only the way between the two parties to cooperate.

Although lithium batteries usually refer to batteries that contain lithium (including metal lithium, lithium alloy and lithium, lithium polymer) in the electrochemical system.

But if you say it, lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are usually non -charged, and lithium. Lithium ion battery contains lithium with metal.

And can be charged.

Although I know that Exxon Mobil is a researcher at lithium batteries, Catherine does not know whether the lithium battery studied by the other party is a lithium metal battery or a lithium -ion battery.

Knowing how the other party made the battery, Catherine could not be sure what the battery the other party was studying.

(But I seem to remember that the lithium batteries before the 1980s cannot be charged ...)

Catherine recalled it carefully in his mind.

"... by the way, graphite, is there a graphite in the raw materials inside?!"

Catherine was interested at this time.

Catherine's knowledge in this piece is very poor. She only knows that the early batteries seem to have added graphite before they have charging performance.

It's just a pity that they have very few relevant information, and there is no way to determine this.

"What can graphite? What can graphite do?"

Catherine couldn't answer the question of Elsa, because she didn't know what the principle was in it at all. She just knew that of this that needed graphite ...

When the book is used, Fang hates less. Catherine now can't wait to carry a 21 world of Baidu Encyclopedia and Wikipedia. Although the things in it are really unreliable, when you want to find a little reliable information, you want to find a more reliable information.

It seems that it is okay.

Catherine's idea is very good, but the historical process is not as good as Catherine imagined.

Historically, in 1982, R.R.AGARAN at Illinois University of Technology found that lithium ions have the characteristics of embedded graphite. This process is fast and reversible.

Then, because of the safety hazards of lithium batteries made of metallic lithium, people tried to use the characteristics of lithium ions embedded in graphite to make rechargeable batteries. After that, the first usable lithium ion graphite electrode was successfully trial-produced by Bell Labs

.

When it was truly commercialized, it would take until the 1990s. ExxonMobil cooperated with Sony of Japan, and finally launched the first generation of lithium batteries in the early 1990s...

At this time, there were only metal lithium batteries. However, due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements, so lithium battery production must be in a special environment.

It is carried out under environmental conditions. Therefore, this kind of battery is very prone to various explosions, and it is almost impossible for civilian use.

Historically, ExxonMobil can be said to have been a favorable promoter and user of lithium batteries...

Maybe the lithium batteries of this era are not good enough, but Catherine believes that as long as she can concentrate on research, it should be relatively simple.

Maybe some plans do take a long time to complete, but most things don't develop very quickly because they haven't been paid enough attention in history. But if we go all out on research and development, maybe we can do it very early.

Got the product Catherine wanted.

"We just don't know if ExxonMobil is interested in this plan."

This issue is very important to Catherine, because Catherine has a blind eye on this matter, so whether she can cooperate with the other party is related to her ability to apply lithium batteries in advance. If she can produce commercial lithium batteries ten years in advance,

, very helpful for Catherine's plan.

——Speaking of which, although Catherine only remembers "graphite", just such a keyword is equivalent to ten years of development of lithium batteries.

Knowledge is power, this is the truth.

"Elsa, please give me a list of companies under the venture fund, and I will see if I can acquire several new energy development companies."

Catherine asked.

His entrepreneurial fund was originally created by himself for batteries. Although Soros seems to be interested in solar energy, he will not forget the normal operation of this fund.

Catherine decided to acquire several battery companies, then unify them all, and then let the companies negotiate and cooperate with each other.

It is not difficult for Catherine to establish a relationship with Exxon Mobil.

The history of ExxonMobil can be traced back to the Standard Oil Company founded by John Rockefeller in 1882. It is currently the largest oil company in the United States and one of the seven largest and oldest oil companies in the world. Its companies include related

and the holding company currently employs more than 80,000 people. The company’s business scope covers 80 countries around the world.

In many countries and regions, its business is mainly energy, with petroleum, petrochemicals, coal, minerals and electric energy all belonging to its advantages. It is the world's largest comprehensive company engaged in oil exploration, production, transportation, refining, processing and sales.

The company is also the largest supplier of chemical raw materials, solvents, additives, intermediates and polymers and other petrochemical products.

In other words, this company is considered a very important profit-making organization under Rockefeller.

Maybe Rockefeller's loan to his own, there is a shadow of Ex SenMobil.
