The time quickly entered the beginning of June, and with the help of Li Guocheng, who knew the general direction, the material group achieved phased results.

One day, the horse worker knocked on Li Guocheng's laboratory.

"The good news, based on your last experiment, we found a stable ratio of lithium-ion anode materials, and the energy density of the battery exceeds 100Wh/kg when mixed with this ratio of phosphorus and cobalt.

Charge and discharge have now been tested on 10 samples 500 times, with a maximum performance drop of 15%."

Excitedly, the horseman said the above conclusion in a trembling voice, and handed over the ratio data sheet.

"Great, prepare 100 sets of battery packs with such a ratio, 10AH each, no problem, right?"

Although the energy density of the battery cannot be compared with later generations, after all, this is an epoch-making initiative, and with it, Li Guocheng can do a lot of things.

Ma Gong hesitated for a moment, thinking that it was better to intervene less in the boss's affairs, "Okay, chairman, be ready within a week."

"Chen Yuhe, you call Mr. Chen over."

A few minutes later, Chen Li came to Li Guocheng's laboratory, and he instructed Chen Li in front of the horse workers.

"Mr. Chen, when they verify that the parameters of the lithium-ion battery meet the requirements, they will be rewarded according to the specifications of the semiconductor team. At the same time, a patent group will be arranged to apply for patents".

After hearing Li Guocheng's words, Ma Gong's face turned red, money is very important, but being able to get the company's attention makes them even more excited to engage in research.

Instead, he was a little embarrassed, "Chairman, this is not good, after all, it was really improved on the basis of your experiment."

"Don't be embarrassed, real innovation is based on the research results of predecessors. And I also learned on the basis of your research."

"You don't have to be humble, just add the name of the chairman when the patent is signed."

This is Chen Li, who knows what Li Guocheng needs.

"Okay, I see," the horseman suddenly realized and left the laboratory happily.

Two days later, Li Guocheng, who had obtained stable experimental data, affirmed their achievements. Immediately before noon, most of the employees of Longhua Technology Company knew that the great achievements of the materials laboratory also knew that they had been rewarded with a comparable level to the semiconductor group.

From this day on, Li Guocheng temporarily put down the research on batteries, and asked Ma Gong to consider product application design. He switched to designing small high-temperature furnaces himself.

Based on his previous experience, the high-temperature furnace designed by Li Guocheng is not only compact, but also the heating and heat preservation efficiency is obviously maximized, and the internal space is guaranteed to fit 4-inch wafers.

According to the possible needs of the future, a small chip packaging equipment was redesigned.

The design principle is to do it manually if he can do it manually, because he trusts his hands more.

These things, with sufficient resources, were designed and produced in a week.

The Secret Realm Test Bench is now lined with high-temperature furnaces and packaging equipment that shimmer with a primal metallic luster, and from now on, the Secret Realm Laboratory will finally be activated.

Because there was no electricity in the secret realm, when I was in the rolling mill, I thought about designing a high-performance diesel generator, and later the rolling mill laboratory was established, and a lot of work was put on the table, so I gave up the research and development of diesel generators.

Now that it has run to Xiangjiang, some high-tech products cannot and dare not appear in Longhua Technology. I once thought about placing it in the basement of the villa, but in the end I chose the secret place due to the confidentiality and security.

Materials Research chose to develop batteries because there is an urgent need. With the blessing of the banknote ability, it is now finally possible to use the secret realm laboratory.

Looking at the equipment on the test bench, Li Guo was overjoyed.

Sitting in front of the test bench, he is holding a 3-inch wafer in his hand, on which is his hand-carved micro-processed KT32F102M. A full 108 pieces, which is twice as dense as the finished product of the latest lithography technology in China.

This is the micro-carving skill under the blessing of telekinesis, which does not require a mask, lithography machine, etching machine, and directly micro-engraving a 3-layer structure.

Now the wafer is already available, and only the Dongfeng battery pack is owed.

The current battery pack is simply connected with wires, and there is no control chip and circuit, so the unbalanced work of the battery is very easy to damage.

For safety, Li Guocheng protected each group of batteries with a double-layer steel plate box, and the two layers were sealed with fine sand. Even if spontaneous combustion occurs, it does not threaten surrounding items.

I don't know when, Li Guocheng's practice room, added a piano, compared with the surrounding equipment, it looks nondescript.

His reason is that his own space, no matter how you fiddle with it, is not embarrassing.

Today, I was really anxious to wait for the battery pack, so I ran here and played the etude "To Alice".

When playing the piano, the fingertips of both hands touch the keys lightly, beating to the melody. The notes swayed in the air, intertwined like an invisible picture, making Li Guocheng feel as if he was in it for the first time.

At this moment, he felt his heart being touched gently, and a pleasant emotion flowed through his heart. The whole process is a quiet and beautiful enjoyment, intoxicating, as if to confide in someone.

At the end of the song, the door was pushed open, and it was Ah Rong, Su Junrou and Chen Li who walked in.

"Aaron, didn't you put on the record just now, it's impossible! You are a big man with your feet, how can you fiddle with the piano", Ah Rong finished speaking, and looked around in a funny way.

Su Junrou patted her hands lightly, and her eyes softened, "Yes, I originally wanted to remind you that it's time to practice, but I didn't expect that you would practice here in private." And after listening to your playing, I can already become a teacher, and the only thing that is lacking now is a lot of practice."

"Haha, to celebrate your graduation, let's have a drink together in the evening", Ah Rong said happily.

The beautiful teacher did not refuse this time, Li Guocheng hesitated a little in his heart, and called Chen Li.

In an old Italian restaurant in Central, 4 people sat together, today's main meal Li Guocheng ordered Florentine Tin bone steak, Chen Li and the beautiful teacher ordered pasta, and Ah Rong chose Italian tripe buns.

Several people whispered music and ate their own food.

At this time, Chen Li was a little restrained, and Li Guocheng, who was more upscale than this, also took her to eat, but today she was obviously sluggish, taciturn, not good at talking, just bowing her head to eat.

Li Guocheng smiled, and regardless of etiquette, he cut a small piece of steak and put it on her plate, and put a chopstick noodle in his mouth.

Chen Li paused for a moment, looked up at him in surprise, and a hint of a smile broke out of the corner of her eyes for a moment, then her face turned crimson, and she lowered her head to eat.

The people opposite and next to him were obviously stunned, Ah Rong was helpless, and Su Junrou's face seemed to be even colder.

It's not that Li Guocheng didn't have any ideas. After all, a big beauty has been together for so long, from the beginning of the routine, to acceptance, to the current appreciation.

When the two were alone, they slowly cultivated some tacit understanding, and with one gesture from her, Li Guocheng was able to play the effect she wanted, and every encouraging smile made him a little intoxicated.

As they got along for a long time, he slowly learned that their daily routine was the result that Uncle Ah Rong and her parents were willing to see.

Ah Rong even spread the word that as long as he gave up his previous marriage, they would facilitate this marriage. For Li Guocheng, this is completely unacceptable.

Because his heart is in the north, where there is his lover and lovely daughter.

And she also has a platonic view of love, pursuing spiritual communication and rational spiritual purity of love. These made Li Guocheng dare not approach.

Isn't it fragrant to engage in scientific research? Women only affect the speed at which he conducts research.

After the meal, Su Junrou dropped the sentence 'You have graduated', and then turned around and left the restaurant.

Ah Rong said hello with a smile and hurriedly chased after him.

"Don't you regret it!" , Chen Li stood beside him and asked quietly.

"It's enough for me to have you", Li Guocheng took her shoulders and left the restaurant.

Looking at her sweet expression, Li Guocheng wondered if she understood them as them (mother and son), not them (and them in the north).

Li Guocheng didn't break it either, anyway, she already knew that there was his family in the north.

Now he has made no secret of such a chaotic relationship, and has become at ease, is this a manifestation of a man who becomes bad when he is rich.

Phew, scumbag.

A week later, Li Guocheng got 200 sets of batteries, because he felt that it might not be enough, so he asked for another 100 sets.

Each battery pack is the size of a lunch box. In fact, the battery does not occupy one-third of the volume, and the rest is a protective shell.

Li Guocheng used a wooden rack to assemble all the batteries and connected them to a high-temperature furnace.

Through the test, once fully charged, the high-temperature furnace can work continuously for 4 hours, which is enough.

Li Guocheng couldn't wait to put the elements that needed to be doped into various positions of the wafer, and after checking that they were correct, he carefully put the wafer into the high-temperature box.

Half an hour later, he took out the entire wafer and did not use any instruments, and his subtle telekinesis was the best inspection tool.

After another 1 hour passed, only one edge of the chip, poorly doped, became a defective product, and the other 107 tablets were all qualified.

The next step is to bind and encapsulate very simply, with the only drawback being that it is time-consuming.

A week later, all 107 microcontrollers KT32F102M appeared on the shelves of the Uncharted Lab.

By mid-July 1973, there were enough samples of all the required ADCs, DACs, high-speed op amps, and small and high-power IGBTs.

The circuit board is hand-engraved copper plated by Li Guocheng, and the 4-layer board is hot-pressed electroplating.

In order to make circuit boards, Li Guocheng redesigned a small hot pressing equipment and an electroplating machine.

Looking at the special control circuit board of the battery pack, Li Guocheng is full of achievements. Replace the damaged battery pack and connect a dedicated control circuit board, all of which are interconnected via 485.

The whole set of control system can monitor the working status of the entire battery pack, balance the current, limit the maximum value, alarm at any time, and automatically cut off the isolation and other operations.

If this control system appears in reality, it will definitely cause a sensation. No matter how powerful Li Guocheng is, he will not be able to avoid being locked up for research and slicing.

July 19, 1973 was a great day for Li Guocheng. Chen Li is pregnant.

Li Guocheng also found that perhaps because of the practice, Li Guocheng's desire to make a woman pregnant is very difficult than ordinary people, which has been verified by all three women.

He didn't know the specific reason, but he would not give up the exercises because of the benefits. For so many years, as long as there are no special circumstances, he has been practicing diligently in the morning class every day.

On the same day, he received a call from Ah Rong, and Su Junrou flew to Sam's Country to participate in the exchange and training between schools.

Li Guocheng, who was in a complicated mood, came to the practice room, played the piano, and sang his favorite "The Love of My Life".

The next day, Li Guocheng threw the patent draft of the IGBT to the patent team.

Now a mechanical equipment laboratory has been added, which is proposed by the semiconductor laboratory.

Now the 4 laboratories have increased to 50 people, and the materials group has the largest number of 20 people; The semiconductor group was increased to 10 people; The mechanical group is now 5 people; The game group was increased to 15 people.

With the help of Li Guocheng, the tasks of each group rarely took detours. When he encounters a problem, he can find a solution under normal circumstances.

Therefore, Li Guocheng arranged the tasks, and they were all carried out smoothly.

Finally, at the end of August, when Li Guocheng completed the secret experiment, he heard the news he wanted to hear the most: semiconductor monocrystalline silicon broke through the 4-inch process.

In mid-December of the same year, the news came that the production line had been successfully imitated. In fact, it is no longer necessary to say that it is imitated.

The current production line is a 4-inch process, and the lithography accuracy has been improved from 100um to 20um, which is not an exaggeration to say that it is a new generation line.

When he applied to the Department of Science and Technology to establish a second production line, he attracted the attention of Director Butler, and his first reaction was that Longhua Technology plagiarized, and he originally came to Longhua Technology with anger and disappointment.

However, when I saw that the new production line was completely different from the original production line, I was deeply shocked.

When I learned about the specific parameters, I had already determined from my heart that this was Longhua Technology's own product.

When he sent the information back to Robin Hood, it was all skepticism at first. After several rounds of bickering, the arrogant Robin Hood issued an order requiring Longhua Technology to submit a full set of drawings and materials, and temporarily banned the manufacture and sale.

When receiving the notice from Director Butler, all the senior management of Longhua Technology were extremely angry, and everyone expressed their resolute refusal.

"Everyone is quiet, this is the end of today's meeting, what to do, I will deal with the next things."

Li Guocheng had to suspend the meeting because everyone was swayed by emotions and could not come up with a solution.

At the same time, an order was issued to the entire company that some of the company's new technologies should not be disclosed before obtaining patent approval.

Then he found Jingjiang Law Firm for the first time.

When lawyer Miller heard all the news, he was excited on the spot, and he knew this was an opportunity to make a name for himself.

"Mr. Cheng, don't worry, this time we are reasonable, and their request is illegal. I'll give you a satisfying answer."
