Technology company, I will become the light of China!

Chapter 279 "China" chip project established!

"Sulfide all-solid-state battery?"

Chen Xing repeated it.

In the WeChat message in the morning, Gu Ren did mention all-solid-state batteries. If nothing else, he should be talking about the so-called "sulfide all-solid-state battery."

"Yes."

Lingchuan nodded.

Although he did not bring the scientific research materials of "Sulfide Solid-State Battery" with him, he already knew the content of the research by heart.

"As I just said, if there is no substantial breakthrough in the field of heat dissipation, you may be able to wait for the release of our sulfide all-solid-state battery, because the thermal stability of sulfide is much higher than that of polymers."

"Chief Ling, I'm a little confused." During the pause of Lingchuan, Liu Ziheng, the chief of the cooling laboratory, immediately asked: "Just now we knew about solid-liquid hybrid lithium batteries, and now you propose this sulfide solid-state battery, what do we know about it?" How many research directions are there?”

"Three."

Lingchuan responded without hesitation.

The final sulfide solid-state battery is not perfect. It is prone to chemical reactions in humid environments. If this cannot be solved, it is impossible to tell users not to drive on rainy days, right?

"Since there is still some distance before the commercial use of solid-state batteries, let's not rush for the moment and use solid-liquid hybrid lithium batteries to make battery packs."

Star Flash fast charging is only 300W?

Chen Xing roughly understood.

As for the oxide solid-state battery, its conductivity and thermal stability are excellent, but it has a relatively fatal shortcoming, that is, the particles are rigid and prone to poor contact and sudden short circuits.

but!

Of course.

After listening to Lingchuan's explanation, Chen Xing also had a preliminary understanding of his own solid-state battery and asked: "How soon will this sulfide solid-state battery be commercially available?"

"I see."

Because there is no resistance, there is no power loss. Without this power loss, the battery will not heat up, and fast charging technology will officially reach its peak.

This is why some people say that if room-temperature superconducting materials come out, the first field of reform will be the battery energy field.

It can be used to improve lithium batteries.

60kWh is 60 kilowatt-hours of electricity. Neither Lingchuan nor Gu Ren felt any pressure. They even felt that this number could be doubled.

"Half a year."

"Understood." Yang Bochao also nodded, his eyes filled with fighting spirit.

"understood."

“Although the thermal stability is inferior to that of oxide batteries, oxide batteries have the problems of large particle rigidity and poor contact. They can only be sintered into blocks at high temperatures to eliminate the grain impedance.

"Sulfide particles are soft and can exhibit high ionic conductivity by simply cold pressing the powder."

Chen Xing made the decision directly.

In the past, it was limited to 300W because the mobile phone was the size of a box and there was no way to install liquid cooling inside.

Polymer solid-state batteries are the least difficult to develop. Their electrical conductivity and thermal stability cannot meet the requirements of solid-state batteries, and their performance is mediocre in all aspects.

Because lithium batteries have a temperature critical value, for example, the temperature of the electrolyte is 200 degrees, while the temperature of the traditional separator is 40-60 degrees. Once the input power is too large, the heat energy converted by the resistance exceeds this temperature, and the lithium battery will detonate.

"Ok."

But building a car is different. It has a large operating space. As Chen Xing also said just now, the battery pack is equipped with liquid cooling. This method can completely cool down the battery temperature quickly.

"Because the sulfide solid-state battery not only has high electronic and ionic conductivity, but also has a higher lithium ion migration coefficient than the other two, and its thermal stability is also higher than that of polymer solid-state batteries."

There has been no substantial progress in room temperature superconducting materials so far.

"Oxides, polymers and sulfides have different advantages and disadvantages in batteries in these three directions, but sulfide is the most suitable."

"Well, there is still an unresolved moisture problem." Lingchuan nodded slightly and continued to explain: "Most sulfides can react with humid air and have poor chemical stability, but we have also found a solution."

"So long for half a year?"

The newly developed solid-liquid hybrid lithium battery uses polyvinylidene fluoride-based polymer as the separator of the battery, bringing its heat resistance to a new level.

Currently, our company's solid-state batteries have three research directions, namely oxide solid-state batteries, polymer solid-state batteries, and sulfide solid-state batteries.

In one sentence, 300W is not the upper limit of fast charging technology, but the upper limit of heat dissipation technology. Without considering heat dissipation, the power can be infinite.

After thinking about it, solid-liquid hybrid lithium batteries are more reliable. At least the manufacturing process of lithium batteries is very mature. If you want to use solid-state batteries, you still need to solve the existing defects first and ensure that they are foolproof before using them.

Can exhibit higher ionic conductivity. "

Immediately afterwards, he glanced at Gu Ren, Ling Chuan, Liu Ziheng and Yang Bochao respectively, and assigned the task: "Battery energy, fast charging technology, and cooling technology, your three laboratories, make a usable battery pack as soon as possible."

"Which three?" Liu Ziheng continued to ask.

These are all things for later.

Just imagine, if Chen Xing uses oxide solid-state batteries to make a new energy battery pack, once the vehicle has a short circuit while driving, the consequences will be disastrous.

Without considering battery overheating, the charging power of fast charging technology is unlimited.

"For the first battery pack, I hope it will have a battery capacity of 60kWh under the premise of safety, with no upper limit. I will send you the specific vehicle design drawings later."

Do not!

This is definitely not the limit value of fast charging.

……

After listening to Chen Xing's arrangement, Liu Ziheng, chief of cooling technology, was also full of confidence and responded: "We have forward-looking technology in terms of batteries. It should be relatively easy to develop battery packs. It depends on the subsequent vehicle assembly."

"I have a question."

At this time, Gao Zhengqian suddenly spoke.

Everyone focused on him, and Chen Xing also looked at Gao Zhengqian and said, "Do you have any questions, Chief Gao?"

"Cars all have main control chips. President, if you want to build new energy vehicles and design energy management chips, our chip laboratory should work with them."

Gao Zhengqian didn't know why Chen Xing wanted to build a car, but since he said he was going to build a car, he would definitely support it unconditionally.

"That's the truth."

Chen Xing nodded slightly, but changed the subject and said, "But you already have a memory chip task, and I plan to delegate it to someone else to develop this new energy chip."

Obviously, he wanted to say that he would temporarily recruit chip talents and set up a new energy vehicle chip design laboratory.

In Chen Xing's business landscape, he wants them all, whether it is high-capacity memory chips or new energy vehicle owner chips!

Needless to say, memory chips above 128G will be weakened again as long as they are developed.

New energy vehicles are the key. They are the future trend and the direction of Longguo's future development.

Like the current fuel vehicles, many people in Dragon Country may not know that the patent wall built by internal combustion engines has not been broken through by Dragon Country car companies even ten years later.

It is no exaggeration to say that the field of fuel vehicles has been completely closed down by the West, and there is basically no possibility of overtaking it.

But new energy vehicles are different!

This is completely new territory.

Its composition is also very simple, with core technologies in four aspects: battery, motor, electronic control and differential reduction system. In the field of batteries, it is no exaggeration to say that Longxing Technology is far ahead.

As for the other three, Chen Xing has the system's talent market in hand, and he doesn't believe that he won't be able to develop them.

Once Longxing Technology masters the field of new energy vehicles, it will be closer and closer to building a complete product ecological chain.

The most important thing is that new energy vehicles are a potential trillion-dollar market, and he does not want to let Masik's Tesla family dominate.

Moreover, the visit of Masik on behalf of the Angsa Military-Industrial Complex also reminded Chen Xing that he should not only focus on one field, but must make substantial industrial upgrades.

……

After listening to Chen Xing's explanation, Gao Zhengqian shook his head and said: "The memory chip with 300-layer stacking technology has been completed and will be ready for trial production within ten days. My team will do their part in the new energy vehicle chip!"

His tone was firm and left no room for error.

Every time Longxing Technology has technological innovations, Gao Zhengqian’s team has not fallen behind, and they will not fall behind this time.

"Is it the simulation verification stage?" Chen Xing felt happy and asked quickly.

After being exposed to it for so long, he also roughly knows the various steps of chip design.

If it can be said that trial production can be completed within ten days, then the memory chip must have entered the EDA software simulation verification stage.

Once verified through simulation and confirmed that the internal circuit can operate, the chip can be used to make a photomask.

After the photomask is completed and the internal circuit of the chip is confirmed to be correct, the chip can be officially produced.

"Well, we're here."

Gao Zhengqian nodded.

After receiving the confirmation, Chen Xing also had an idea in his heart and delegated the task: "Since Chief Gao and your team are going to take on the task of designing new energy vehicle chips, let's immediately set up a project to develop 7-nanometer chips."

"7 nanometers?"

Gao Zhengqian was a little unsure.

7nm?

Do they have production equipment?

The design alone is definitely no problem, but Gao Zhengqian considered the production issue. Do they have EUV lithography machines?

The other chiefs were also shocked.

"7-nanometer chip, did I hear you correctly?"

"Hiss! Is it possible that we already have the production conditions for 7-nanometer chips? This is a nanometer level that no one in the world has conquered!"

"The commercial application has not been conquered, but the military application is hard to say."

"To design 7-nanometer chips, is it possible that we already have photolithography machines?"

The chiefs discussed among themselves.

On the other side of the conference room, Gu Ren was a little confused now.

When he joined Longxing Technology, 28-nanometer chips were still mainstream. A year later, various manufacturers have moved to 14-nanometer chips, directly surpassing 20-nanometer chips.

But now!

7nm chip? ? ?

This speed can no longer be described as fast, but as fast!

Because they are all members of his own family, Chen Xing did not hide anything and told what happened in Tooguling: "I know you have many questions, but what I can tell you clearly is that the lithography factory that replaces the lithography machine has already It was built and trial production completed.”

"hiss!!!"

The chiefs took a breath.

Replace the photolithography machine!

There is actually a machine that can replace the photolithography machine!

Gao Zhengqian also flashed a hint of surprise and hurriedly asked: "In other words, this photolithography factory has extreme ultraviolet light with a wavelength of 13.5 nanometers?"

"No!"

陈星摇了摇头，全盘托出道：“它不仅有13.5纳米波长的极紫外光，它还有3纳米、7纳米、10纳米、20纳米、28纳米，甚至连48纳米的深紫外光都有。”

Gao Zhengqian: "..."

Gu Ren: "..."

Chiefs: "..."

They were completely bewildered.

What on earth is this photolithography factory that can emit so many light sources? They have never heard of it.

Chen Xing looked at their surprised expressions, poured cold water on them and said: "We only tested extreme ultraviolet light with a wavelength of 13.5 nanometers, and other light sources were not tested. Moreover, there are still energy problems in the lithography factory, so we should be conservative and design 7 nanometers." Chips are the most reliable.”

In his view, even if other light sources cannot be used, as long as 13.5 nanometer extreme ultraviolet light can be used.

Because of the multiple exposure technology, the theoretical photolithography limit of extreme ultraviolet light with a wavelength of 13.5 nanometers is a 3-nanometer chip.

However, photolithography of 3-nanometer chips requires the cooperation of four photomasks. The photolithography steps and costs are too large. 7-nanometer chips only need one time, and the cost performance is the highest in all aspects.

however.

Gao Zhengqian didn't think so.

He put his hands on the table and said with a serious expression: "Since the 13.5-nanometer extreme ultraviolet light has been successfully verified, the 7-nanometer, 5-nanometer, and even 3-nanometer extreme ultraviolet light must be similar. I suggest either Go to 5 nanometers, or it will be full at 3 nanometers."

"This is a werewolf."

Gu Ren murmured to himself.

Other chief executives were also shocked by these words. The words "3 nanometers" are too scary. This is already challenging the limits of transistors.

Because the smaller the nanoscale, the smaller the gate will be. Once the gate is too small, leakage will be found.

The calculation of the chip is actually 0 and 1. Once a gate leakage error occurs, the calculated data will be different.

According to the content of the journal published by the World Semiconductor Alliance, they believe that the minimum nanometer of a transistor is 3 nanometers. Once it exceeds 3 nanometers, that is, below 3 nanometers, tunneling effects may occur, leading to leakage.

"Are you sure?"

Chen Xing respects Gao Zhengqian's choice.

He also believes that Lin Tian's photolithography factory can manufacture 3-nanometer chips, because these two people have never let him down.

"100%!"

Gao Zhengqian responded with a smile.

Just after finishing speaking, he recounted: "According to my research, the limit of transistors may be 2 nanometers, or it may be 1 nanometer, but it will never be 3 nanometers. I am 3% confident that I can complete the design of 100 nanometer chips." .”

"it is good!"

Chen Xing nodded heavily and delegated the task: "In that case, Chief Gao and our team are responsible for the research and development of 3-nanometer chips. The project is code-named Huaxia. Within six months, I need to see the circuit design diagram of the chip."

He originally wanted to seek stability, but since Gao Zhengqian said so, he was willing to take risks that might occur in the future.

Even if the 3-nanometer extreme ultraviolet light in the photolithography factory cannot be used, it still has multiple exposure technology, and 3-nanometer chips can definitely be produced. It is just a question of the cost.

"Six months is enough." Gao Zhengqian responded lightly, with that iconic smile still hanging on his lips.
