Arms Tycoon: Started by cheating on tens of billions of dollars in orders

"What? Dr. Zhao, you said that a super battery full of blood from the laboratory was sent to the Imperial Capital Testing Institution! ?"

In the research room of Feng Yi Technology, Lin Yi asked in surprise

"Yes!"Zhao Xuebin is also helpless.

You must know that under normal circumstances, lithium battery identification requires a third-party testing agency or certification agency with relevant qualifications, such as a laboratory accredited by the General Administration of Quality Supervision, Inspection and Quarantine or a CMA laboratory.

However, today This battery was taken by mistake by a researcher in the laboratory.

A cobalt-removed super battery from the laboratory was sent for testing, and the performance of this battery was that of the battery from the Magic City Sports Center last time. Nearly three times.

However, it was precisely because the performance was too advanced that Lin Yi and Zhao Xuebin decided to reduce its performance for release. However

, no one expected that the laboratory accidentally leaked this battery.

Ji Yi couldn't do anything. He could only say that there was something wrong with the company's laboratory management.

Fortunately

, it was just a battery. However, he did n't think so.

I don’t know.

In a confidential research institute, the unit responsible for national electromagnetic technology research is currently testing a battery very formally.

Standing next to it are several experts from the institute, one of whom is a famous figure in Long Country. Chen Quan, a battery expert and academician of the Academy of Engineering, and Yang Yusheng, an 80-year-old academician of the Academy of Engineering, both came to the institute after hearing the report.

"Xiao Zhang, are you sure this battery has the performance you said on the phone? Considering the technology of lithium batteries, it is incredible!"

Academician Yang Yusheng said

"Mr. Yang, I came here just after I heard about it!"

Director Zhang Weibing, head of electromagnetic technology research at the institute, said.

Hearing this, academicians Chen Quan and Yang Yusheng fell silent, waiting for the laboratory test.

However, as the test ended.

Everyone present took a breath. Angry.

It can be said that they were all shocked by this battery technology.

Academician Yang Yusheng’s eyes widened and he hurriedly asked:

"Which military research institute is this product? This performance is really incredible...."

In Mr. Yang's view, the company that can develop batteries with this kind of performance must be the country's cutting-edge military research institute.

However, researcher Wang Qiming, who was the first to discover the performance of this battery, had a weird look on his face.

Until his boss, Director Zhang Weibing, came over and Wang Qiming immediately explained the origin of the battery.

He got the commissioned testing project from a CMA laboratory.

As far as he knew, the certification party for this battery was a private company called Fengyi Technology in Shanghai.

"Private~?"Academician Yang Yusheng looked in disbelief.

Not to mention him, all the electromagnetic experts from Longguo present could not believe this fact.

Such a good battery did not come from a domestic cutting-edge research institute, but from a private company.

When did private technology become so powerful?

However, these experts thought about it.

It is not too unusual for private enterprises to surpass the national formal research institutes in some aspects.

For example, in the past two years, Longguo's first ship was launched. After undergoing a series of modifications and tests, the aircraft carrier was officially delivered to the Navy.

However, the aircraft carrier at that time faced a serious problem: the lack of aircraft carrier arresting cables, which plays a vital role in aircraft takeoff and landing. , but Longguo did not have ready-made supply channels at the time, and after seeing Longguo's embarrassment in this regard, foreign countries actually offered an astronomical price of 1.5 million US dollars for one piece.

However, at this time, a company named Julisuo. Private enterprises in the industry have become a key force.

This company specializes in manufacturing various types of slings and rigging.

At first, they did not consider getting involved in the field of aircraft carrier arresting ropes because the requirements in this field are extremely high and the order volume is not large.

However, an order came from. The U.S. military's intention order changed everything.

The U.S. military has been looking for cheaper suppliers of aircraft carrier arresting ropes, because the price of aircraft carrier arresting ropes is extremely high and its service life is limited, which has led to layers of subcontracting by suppliers. In the end, the price was reduced to only half, and Juli Rigging emerged during this period. Their rigging was cheap and of reliable quality.

Therefore, the Chouguo blocking rope supplier reached a cooperation agreement with Juli Rigging. The latter OEM manufactured a batch of special elastic slings.

During the production process, Juli Rigging obtained key information about the arresting ropes, including performance parameters and manufacturing processes.

This cooperation once made Juli Rigging doubt whether they could. It has been manufacturing aircraft carrier arresting ropes for the Ugly Kingdom's military (to read Baoshuang novels, go to Feilu Novel Network!)

Later, the problem of the lack of arresting cables for the Dragon Kingdom's first aircraft carrier became a key force to help Long. The country independently developed its own blocking rope.

This can be said to be a rectification of the reputation of private enterprises.

Later, Longguo conducted an industrial survey and discovered the cutting-edge technology of many private enterprises, which showed their flexibility in the industry. Deep research[]

Since then, industrial probing has become a national norm.

Obviously, this is also the case with Fengyi Technology.

This time the battery was tested and the peak energy density was as high as 1178Wh/kg.

This energy density is 10 times that of traditional lithium iron phosphate batteries and 5 times that of ordinary ternary lithium batteries on the market.

The most exciting thing is that this super battery uses a cobalt-free positive electrode, a solid electrolyte and a carbon-silicon negative electrode, and the entire battery core adopts a heterogeneous structure.

This is a cutting-edge technology for lithium batteries.

The advantage of this structure is that its charging and discharging speed is faster, taking only 30 seconds. Under high voltage conditions, a 200KW battery can be fully charged in an instant.

Other than that, it's very small.

Compared with lithium batteries of the same quality, the volume is only one-third of the other.

This means that this battery serves as a power reserve battery for laser weapons.

Or it can be used as the energy supply for electromagnetic ejection on aircraft carriers.

The so-called aircraft carrier electromagnetic ejection is a device that accurately controls ejection acceleration through a control system to allow aircraft to take off quickly from an aircraft carrier.

The catapult sounds very simple, it is just a linear motor, but it can accelerate a 30 to 40 ton fighter jet to the 240 kilometers per hour required for takeoff in 2 to 3 seconds.

The energy required during this period How big is it? Here is a simple calculation:

Assume that a 35-ton heavy fighter accelerates to a take-off speed of 240 kilometers per hour in 3 seconds.

Its kinetic energy is approximately: 7.76223e+8J.

This kinetic energy is approximately: 215 kilowatt-hours.

The power is approximately It is: 258.741KW. The general ejection interval is about 50 seconds, so the charging system must fully charge this lost power within 50 seconds.

Therefore, the power of the charging system is approximately: 15.524.46KW.

Calculated based on the catapult efficiency of 50%, charging Calculated with an efficiency of 80%, the charging power will increase to: 38.811KW; if calculated based on the three catapults of the aircraft carrier, it will require 116.433KW.

If it is staggered a little, such as changing the simultaneous ejection of three catapults to three ejections in 100 seconds, the power can be reduced to 77.622KW.

From here, we calculate the 215 kilowatt-hours required for an ejection, and the other is the charging power of approximately 16.433KW.

If we follow these two data, this 215 kilowatt-hours (for Haonuo) must be converted into ampere-hours, with a DC voltage of 3000V. It is about 3000V/72AH and needs to be discharged within 3 seconds. The required current is about 86.400A and the discharge speed is about 1200C.

What is the concept of C? In fact, it is the discharge speed of the battery. For example, a commonly used 18650 lithium battery, assuming its capacity is 6000mAh and discharged at 5C, the maximum current is 30A, and the discharge at 10C is 60A.

The higher this indicator is, the better the high-speed discharge performance of this battery is.

Now on the market, the discharge speed of better lithium batteries is around 75C.

But Fengyi Technology’s cobalt-free lithium battery has a maximum discharge rate of about 310C.

This means that only four batteries need to be connected in parallel to achieve the 1200C discharge effect required for aircraft carrier ejection.

It can be said that this new battery was accidentally discovered, which undoubtedly solved the problem of aircraft carrier electromagnetic missiles hitting the battery pack, and can also provide energy for the research of domestic laser weapons.

Its significance is naturally extraordinary
