Next, Xu You measured other properties of this material.

Through measurements, Xu You found that when this material is used as the positive electrode material, the reversible cycle capacity is very high, which is about 50% higher than that of the traditional lithium battery positive electrode material.

This can improve the overall energy density of the battery and increase the endurance of the battery.

For a battery of the same size, if this material is used as the positive electrode, the battery will have a higher capacity.

At the same time, if you focus on the thinness of the mobile phone, you can also reduce the battery size, so that its battery life is still very good.

After confirming the excellent performance of this material, Xu You approached Cui Ying to study the issue of patent application.

According to the plan, Xu You will hand over the right to use this technology to Luo Wenkun's Fulong Technology, and according to the procedure, he must apply for a patent.

In fact, in terms of disclosure, patents are not as confidential as technical secrets.

However, the degree of legal protection of technical secrets is very weak. In contrast, patents are protected by the state and have a stronger legal status.

Due to the cooperation between Xu You and Luo Wenkun, it is still a better choice to apply for a patent.

"Mr. Cui, it is still difficult to handle patent writing. It is necessary to show the necessary information and keep the core technology secret."

"Okay, Mr. Xu, I will take it seriously. After I finish writing, I will show you."

After arranging this work, Xu You did not do other subjects, but continued to study this material.

There is still room for improvement in the material preparation process.

During the first successful preparation, the grain growth rate of the material was somewhat slow.

If a mature processing technology is to be achieved, the growth rate of material grains must be as fast as possible.

Xu You and several teachers got together again in the material laboratory after setting a time, and began to experiment on the optimization scheme of material preparation.

"This time, we added parallel substrates in the reaction chamber, which can theoretically increase the growth rate of grains. At the same time, this time the requirements for the environment are more stringent, and we must control various environmental parameters more finely. "

Including but not limited to deposition temperature, deposition pressure, reactant concentration ratio, reaction gas and carrier gas concentration, flow ratio, flow rate and other parameters must be strictly controlled.

This is still very difficult for an experiment in the exploratory stage.

Sure enough, this time the experiment did not go as smoothly as the last time.

The first day passed, and for a whole day, they were unable to control the environmental conditions well, and the ideal grains were not formed.

However, after summing up the experience, everyone finally found a better way to control the environmental parameters, and successfully prepared this material again.

After the process gradually matures, this optimized solution can indeed make the grains grow faster and make the preparation of materials more efficient.

And these harsh environmental factors will not be a big problem after the preparation process is proficient.

Overall, this is definitely a better cathode material for lithium batteries.

After Cui Ying finished writing the patent, she handed over the first draft to Xu You for review.

Cui Ying's patent is very well written, not only meeting the requirements of the patent, but also retaining the core secrets of this technology to the greatest extent.

"Okay, there is no big problem, just apply according to this version. Also, please contact Luo Wenkun for me, and I will talk to him about the use of the patent."

"Okay, Teacher Xu."

In the evening, Luo Wenkun came to Xu You's office.

"Xu You, has there been a breakthrough in research?" Luo Wenkun excitedly asked.

"Well, this material is indeed very suitable for the positive electrode of lithium batteries. According to the experimental test data, the overall energy density of the battery can be increased by 50%."

Hearing this news, Luo Wenkun became even more excited.

As the boss of Fulong Technology and a technology enthusiast, Luo Wenkun naturally knows what this means.

"Great! The next generation of Fulong mobile phone, I plan to make a thin and light model, this should be a very good selling point."

At present, the battery power of mobile phones on the market is mostly around 4000mAh.

Such power is basically sufficient for daily use.

But such a mobile phone often weighs more than 200g, or even half a catty.

There are some inconveniences in use and carrying.

Especially when lying down and playing with a mobile phone, if it is not held firmly, it may cause severe damage to the face.

This is a common pain point of mobile phones at present.

And if the power of the mobile phone is sacrificed to make the mobile phone thin and light, it will face battery life problems and require frequent charging.

Therefore, it is the best choice to improve the overall energy density of the battery.

"Why don't you consider making a strong battery life version? With the same quality, the battery life is 50% higher than before. I believe it will be favored by many users."

As the power of the mobile phone is getting higher and higher, the increase in the power of the mobile phone does not bring about an increase in the screen time of the mobile phone.

A mobile phone with a long battery life can greatly save the trouble of frequent charging.

"Personally, I still prefer thin and light models... Well, I mean mobile phones. However, models with super battery life can also be considered. When we go back, we can make a poll on the Xueba community to see what everyone is like Idea. If the turnout rate in both directions is similar, we can also directly make two versions, one Fulong 2, which focuses on thinness, and one Fulong 2pro, which focuses on battery life.”

Xu You didn't understand for a while, why Luo Wenkun wanted to explain behind the frivolous money, but seeing that Luo Wenkun hadn't finished speaking, Xu You didn't rush to ask.

"Xu You, have you applied for this patent yet?"

"We are going through the application process. The core technology has been kept secret, and no one knows except me and a few teachers in the laboratory. The non-disclosure agreement has been signed, and normally there will be no problems."

To be on the safe side, Xu You did not communicate with anyone about the details of material preparation.

Even if those teachers were asked to repeat the experiments they had prepared, it would be difficult to reproduce them.

"I'm sure you'll be very assured of what you're doing. Let's talk about cooperation after the patent application is approved. In order to ensure that the next generation of Fulong mobile phones can use this technology, we have to carry out research as soon as possible."

The positive electrode material of lithium battery is the most critical technology of lithium battery.

But not all lithium batteries are made of.

Including anode materials, separators, and electrolytes, these parts also need to be studied.

In addition to these, battery safety issues must not be ignored.
