Reborn in Hong Kong: The Tycoon Grows Up

In order to meet the needs of modern field operations, the U.S. military requires vehicles to be equipped with micro-generators. And it has strong power storage capacity without any power. It can satisfy one light bulb for 72 hours of lighting; that is, it must reserve more than 36 degrees of electricity.

This is definitely a challenge. Once the research and development is successful, the safety will be greatly improved when performing tasks in the wild. The technology of small generators is relatively simple. After all, humans have been using electricity for more than a hundred years and can be said to be very handy.

The difficulty lies in storing electrical energy, and traditional liquid batteries meet the requirements. But the weight and size are really appalling, so it’s okay if you’re traveling by car.

Nowadays, American soldiers drive them out to fight and install liquid batteries, which are no different from living targets. GM and Ford know that it is difficult to do so with existing technology. Putting forward these requirements is more to make manufacturers, including Heiyun Automobile, retreat in the face of difficulties, and then they can take the opportunity to propose lower technical requirements to the US Department of Defense, but Bao Zixuan does not think so.

Traditional liquid batteries cannot do this, so Heiyun Group, which is unique in lithium battery technology, can take on this task. It can even be customized for Heiyun Motors. After all, in terms of lithium batteries, even Japanese manufacturers cannot match the technology of Heiyun Group.

The U.S. military, and of course the two automakers General Motors and Ford, are destined to shoot themselves in the foot.

Bao Zixuan has been prepared for a long time. Heiyun mobile phone lithium battery department has been seconded to the automobile factory and needs them to work here for a period of time.

Heiyun mobile phone's algorithm application of lithium batteries is more reasonable, even better than that of the notebook computer department. It's all the credit of Yoel Engel; this great figure from Bell Labs is exerting his brilliance in the Black Cloud Group.

In order to reflect the importance attached to this military vehicle order, Oblak, the actual head of the mobile phone department, personally led the team. Its purpose is self-evident, which is to prove its seriousness.

Bao Zixuan: "Dr. Oblak, these people are all good at developing cars. But when it comes to batteries, especially in the field of lithium batteries, they are blind. You are an expert in this field, let me introduce it to everyone."

Oblak was fully aware of the teacher's painstaking efforts in arranging for him to come here. It stands to reason that an ordinary engineer could complete it. But why did the teacher send him here? Of course it was to communicate with Bao Zixuan and let the boss know more about him.

The Heiyun mobile phone department was handed over to him, but he was too young, so this was not the most important thing. There was too little time to communicate and meet with Bao Zixuan, so even if he had talent, he was not fully discovered. Taking advantage of this opportunity shows that Yoel Engel also has good intentions.

Engineers, especially top engineers. They are just not good at research. If they are dedicated to being humane and sophisticated, no one in the world can compare with them.

Another point is that real gold is not afraid of fire, and Yoel Engel has absolute confidence in his protégé. Working with Bao Zixuan will definitely allow the boss to fully see Oblak's technical, organizational and coordination abilities.

Oblak stood up and said: "You are all seniors, and you are the absolute authority in the field of car manufacturing. However, this time the US military has requirements for power supply equipment, and our mobile phone company happened to have conducted in-depth research on lithium batteries. We think we can achieve it Technical requirements, please correct me if there is anything wrong.”

This is more of a polite statement. No one will take the initiative to challenge other people's authority. Heiyun Mobile is definitely the most profitable company in the group, and it can even be said that there is no other company. Not only does it have the highest market share, it is also the most expensive.

In this era, mobile phones are considered luxury goods, and customers do not pay particular attention to price when purchasing them. Paying more attention to product performance and the services provided, Heiyun has made great efforts in this aspect. We also asked fashion designers to design the appearance, which is definitely beyond the times.

Oblak: "According to the technical requirements put forward by the U.S. military, traditional liquid batteries simply cannot meet the technical requirements. Because that would require an increase of at least one ton of weight, and the combat performance will be greatly reduced."

"The group has conducted in-depth research and development of lithium batteries three years ago and has now achieved revolutionary breakthroughs."

"Based on the ternary lithium battery used in mobile phones, a lithium iron phosphate battery was developed."

"Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. The rated voltage of the cell is 3.2V and the charging cut-off voltage is 3.6V~3.65V."

"During the charging process, some lithium ions in the lithium iron phosphate are released, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material; at the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of the chemical reaction. During the discharge process, lithium The ions escape from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy to the outside world.”

"Lithium iron phosphate batteries have the advantages of high operating voltage, high energy density, long cycle life, good safety performance, low self-discharge rate, and no memory effect."

"If you use a traditional liquid battery, it will weigh one ton to meet the technical requirements of the U.S. military. Using lithium iron phosphate batteries, the weight will not exceed 50 kilograms."

Hearing this, everyone showed incredible expressions. This sentiment has directly pushed battery technology forward for 20 years or more.

David Bruce, the person in charge of the assembly and an alumnus of Bao Zixuan's MIT, asked: "Dr. Oblak, with such a small size and such a high energy density, how can safety be ensured? If he is hit by a bullet, Or direct firing of artillery shells, will it bring catastrophic consequences? By then, the parachute incident during World War II may be the black cloud's turn."

This concern is normal, after all, they provide military products. Moreover, if the products are supplied to the United States, their safety performance cannot be guaranteed, which will inevitably lead to endless troubles.

Such a large capacity density if the battery explodes. The explosion of the same mortar bomb is almost the same. Wouldn't it be very dangerous for the US military sitting on it? Because there is a problem with the product itself, the entire company, including the group's top managers, will be severely sanctioned.

Moreover, the parachute story is real, and the U.S. military’s requirements for military equipment can be said to be extremely picky.

This is a true story that took place in the middle of World War II between the U.S. Air Force and parachute manufacturers. At that time, the safety of parachutes was not perfect, and the pass rate was only about 60%. Through the efforts of manufacturers to improve, the yield rate of parachutes produced by parachute manufacturers has reached 99.9%. It should be said that this yield rate is difficult for many companies to achieve even now.

However, the U.S. Air Force said no to this company, and they required that the yield rate of the parachutes delivered must reach 100%. So the general manager of the parachute manufacturer went to the flight brigade to discuss the matter to see if the level could be lowered? Because the manufacturer believes that it is close to perfection if it can reach this level, and there is no need to change it. Of course, the U.S. Air Force refused because there was no discount on quality. Later, the military requested changes in the method of inspecting quality. That is to randomly select one of the parachutes delivered by the manufacturer the week before, and let the person in charge of the manufacturer equip it behind his back and personally jump off the fuselage in flight. After this method was implemented, the defective rate immediately became zero.

David Bruce previously worked for Jeep and developed and improved weapons for the U.S. military during the Vietnam War. It can be said that I have a good understanding of the US military. Putting product performance aside, safety is definitely the first priority. It's normal to raise questions. It's not directed at anyone, it's just a normal work discussion.

Oblak: "You can rest assured about safety; the electrochemical performance of the cathode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process. , will not burn or explode, and is still very safe even under special conditions such as short circuit, overcharge, extrusion, acupuncture, etc.”

"Not only that, we will also wrap a layer of metal alloy outside the battery casing. Unless it is directly attacked by artillery with a caliber of 100 mm or more, there will be no safety problems. Even anti-tank mines will not be fatal to it. harm."

"Although it will increase a certain amount of weight, the overall weight will be controlled within 80 kilograms. With various auxiliary equipment, the overall weight of the power system will not exceed 100 kilograms, which will definitely meet the requirements; it will not hold back the entire project."

Oblak holds doctorate degrees in physics and chemistry, and is a well-known teacher. He has very high technical requirements and his guarantee is very important. Not to mention it represents authority, but at least it can still be convincing. If there are any other doubts, they can only be verified through actual testing.
