Professor Zhang Xi and Professor Lin Lanying were very surprised, but they didn't expect Lin Qiangsheng's technology research and development of lithium batteries to be so advanced. Professor Zhang Xi knows a lot about electronics, and Professor Lin Lanying is an expert in electronic materials, and has also helped a lot in the research and development of lithium batteries. As soon as they heard what Lin Qiangsheng said, they understood the purpose of this product and how to implement this technology.

Previously, the cathode materials for lithium batteries provided by Lin Qiangsheng include lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, and ternary materials. The anode materials are all carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.

In fact, when Lin Qiangsheng proposed to develop lithium batteries, Professor Zhang Xi and Professor Lin Lanying were very surprised. Because of the characteristics of lithium metal, although lithium batteries are widely favored, its safety has not been solved.

In fact, lithium batteries have been developed since the early 70s, but the research progress has been very slow. Due to the very reactive chemical properties of lithium metal, the processing, preservation, use and environmental requirements of lithium metal are very high. Therefore, the production of lithium batteries should be carried out under special environmental conditions, otherwise explosion accidents are very likely to occur.

However, lithium batteries have many advantages, its specific energy is high, high density, large capacitance, is widely used in electronic instruments, home appliances, many Japanese camera battery rods and watches in the button battery use lithium batteries.

However, the life and safety of rechargeable batteries are poor. Lithium batteries made of lithium metal have always attracted much attention for their safety hazards.

Many scientists and laboratories in Europe, the United States and Japan are committed to studying how to make lithium batteries safer and find more reliable processes to produce lithium batteries.

What Lin Qiangsheng provided to Professor Zhang Xi and Professor Lin Lanying was a lithium-ion battery with carbon material as the negative electrode and lithium-containing compounds as the positive electrode.

In the process of charging and discharging, there is no metallic lithium present, only lithium ions, which is a lithium-ion battery. When charging the battery. Lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move through the electrolyte to the negative electrode. The carbon as the negative electrode has a layered structure, it has many micropores, and the lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer, and the more lithium ions are embedded, the higher the charging capacity.

In fact, this kind of battery is two completely different products from lithium batteries. The active lithium metal is isolated by lithium ions, and its safety has been greatly improved, and it is a product that can be used commercially.

With the widespread use of mobile phones and cameras, lithium-ion batteries are bound to be widely used in such products with excellent performance, and will gradually develop to other product applications in recent years.

Lin also understands the impact of this revolutionary product on other electronics manufacturers, especially Bell Labs, which has already taken the lead in lithium-ion batteries. They mastered lithium-ion graphite embedded technology last year, and if Lin Johnson's mobile phone goes on the market, it will definitely attract widespread attention from the world, and Bell Labs will definitely find out that Dongxing has stolen their technology.

Lin Qiangsheng couldn't help but smile when he thought of this, it was not the first time he had done this kind of thing. I already have experience! I also have other skills, and we first go back and forth to fight a few lawsuits, and then exchange skills. The key is to ship quickly and in large quantities in the first few years before the product is launched, and occupy the market.

However, Lin Qiangsheng also has a headache for the production of lithium-ion batteries, and there is another trouble that has not been solved, and the process production method taken out by the laboratory is too expensive. If lithium-ion batteries are produced in this way, not only will they have to invest in a new production line, but they will also have to recruit a group of workers for a long period of training. Because lithium metal is a very dangerous industrial product, it is also necessary to consider where to set up a factory site. Many counties in the United States do not allow such factories to be built, and the government's approval of local councils will delay the construction of batteries!

The lithium-ion batteries used in the laboratory are produced in small batches. And industrialization is not possible with laboratory products.

It seems that we have to find a way to produce lithium-ion batteries!

Seeing that Lin Qiangsheng suddenly frowned and fell silent, Professor Zhang Xi and Professor Lin Lanying knew that this was Lin Qiangsheng who fell into deep thought again, they looked at each other and shook their heads with a smile before walking away.

Lin Qiangsheng thought for a while, and finally let him come up with a plan, which he estimated was also the fastest way in reality.

"Huh?" As soon as he looked up, the two professors stepped aside, touched his brain, and walked out of the laboratory alone.

Lin Qiangsheng said to Mary Gretel, who was standing at the door, "Let's go." Please have lunch and try the roast beef from our company restaurant, which is very chewy! ”

"Okay, thank you!" Hearing that Lin Qiangsheng invited himself to dinner, Mary Gretel thanked him. Although he used a Chinese word that she didn't understand, Mary could guess that it must be to describe delicious.

After the CIA put a lot of effort into investigating the secret channels of trade between Japan, Norway and the Soviet Union. Sure enough, their attention to Lin Qiangsheng has dropped a lot. He didn't feel the urgency of being watched for a while, and he suddenly felt some anxiety on Mary Gretel, who was supposed to protect him and was actually monitoring his movements.

"Mary, tell me what's wrong with you these two days? I see you're in a bad mood and seem to be in a hurry! At noon a week later, Lin Qiangsheng suddenly asked Mary Gretel beside him.

Mary turned her head to look at Lin Qiangsheng and then avoided her gaze, she said in a low voice, "It's nothing!" ”

Lin Qiangsheng smiled, cut off a small piece of his steak and stuffed it into his mouth, and said, "Haven't you contacted the branch in the past few days?" Orsin is gone! Also, the car that keeps tracking me doesn't seem to be there! ”

Mary Gretel's eyes showed some hesitation, she looked at Lin Qiangsheng and said, "He has more important things!" ”

Lin Qiangsheng asked suspiciously, "What did Orsing do?" ”

Mary Gretel looked at Lin Qiangsheng carefully and said, "The information you provided is very valuable, and Orsing also participated in the investigation!" ”

"Oh, it looks like Olsin's promotion is just around the corner!" Lin Qiangsheng smiled and said teasingly.

A look of loss flashed in Mary Gretel's eyes, and this strangeness was captured by Lin Qiangsheng, and he said with a smile: "Are you disappointed that you can't participate in such an important event?" ”

Mary Gretel glared at Lin Qiangsheng and said, "Of course, as long as I think about it, I will regret taking this mission!" And it's even more unfortunate that you provided me with the information in the first place! ”

Lin Qiangsheng said with a smile while eating: "It's none of your business now, and you don't have your share in such an important action, and I'm still tied here!" ”

Mary cut the steak fiercely, her expression very depressed.

Lin Qiangsheng learned about the CIA's attitude towards him through a conversation with Mary, and he found that the CIA did not seem to regard the few units he owned as too much of a threat, and it was obvious that the equipment was not as important as the intelligence of the Soviet nuclear submarines.

Perhaps it also has something to do with the resumption of military trade between China and the United States this summer, and now is a period of friendship between China and the United States, and China bought a lot of military weapons from the United States during the period from '83 to '89. The attitude of the United States is also very positive, and the relations between the two countries have changed for the better, and this problem of its own seems to have become a minor problem.

Lin Qiangsheng smiled, happy that he had caught up with the good time.

Two days later, Dongxing suddenly held a press conference and brought together many news organizations based in Silicon Valley.

The press conference opened with a beautiful woman with curly brown hair and blue eyes, and the speaker welcomed the media to the scene, and then a large propaganda poster was lifted behind her, exposing herself to the spotlight.

The promotional poster has a white background as the background, and the black mobile phone is tilted in front of everyone, with a large English logo underneath, DX-100, Anycall, Mobile? Telephone！

"Dongxing officially announces our upcoming flagship product, a new generation of mobile phones, DX-100 Anycall!" The beautiful and generous spokeswoman took out a phone half the size of a palm from a small box.

"Oh, it's so small! Is it true?! Many reporters at the scene didn't believe their eyes, and they actually saw that the mobile phone of Dongxing Company was smaller than the palm of their hands.

The spokeswoman compared it with the phone with her own hand, and everyone found that the mobile phone was not the size of a woman's palm, and it seemed that the spokesperson was very flexible and easy to hold it with one hand.

There was a "click" sound of the camera's shutter sounding, and the flash flashed violently.

Under the dazzling flash light, the beautiful spokeswoman still showed everyone unhurriedly, and said: "This is a handheld mobile phone developed by Dongxing Company after 3 years of research, and everyone has seen that its actual size is not as large as my palm, both in volume and in quality, it is very light!" I can even operate it with one hand, it's much easier to use than a mobile phone on the market, and we can even put it in our pocket! ”

She demonstrated it and literally put the phone in her jacket pocket!

"Wow!" There was a sound of amazement from the press gallery.

"Can this phone really make calls?" A reporter immediately asked curiously, and his question was exactly what many reporters wanted to know.

The beautiful spokeswoman smiled charmingly and said, "Then we might as well show its call function on the spot!" ”

She opened the lower flip cover, and the reporters saw that the keyboard was actually exposed under the flip cover, and the camera captured her every movement.

In the curious and puzzled eyes of everyone, the beautiful spokesperson pressed several numbers to dial an internal phone number of the company.

"Hello, this is Tarona and I'm at the press conference!" The beautiful spokeswoman said into the phone, and then she moved the earpiece closer to the microphone.

The scene immediately fell silent, all flashing lights stopped, and the reporters listened intently.

"Hi Tarona, I'm Johnson Lin! What happened? Lin Qiangsheng's voice suddenly came from the loudspeaker at the scene, and the scene immediately shocked off his glasses and pencils (to be continued......
