Chapter 287 I Know What This Means
Next, Xu You measured other properties of this material.
Through measurements, Xu You discovered that when this material is used as the positive electrode material, the reversible cycle capacity is very high, about 50% higher than that of traditional lithium battery positive electrode materials.
This can improve the battery's overall energy density and enhance its battery life.
For batteries of the same size, using this material as the positive electrode will give the battery a higher capacity.
At the same time, if you focus on the lightness and thinness of the phone, you can also reduce the size of the battery while still making its battery life very good.
After confirming the excellent performance of this material, Xu You found Cui Ying to study the issue of applying for a patent.
According to the plan, Xu You will hand over the right to use this technology to Luo Wenkun's Fulun Technology, and according to the procedure, a patent application must be made.
In fact, in terms of the degree of publicity, patents are not as confidential as trade secrets.
However, the legal protection of trade secrets is very weak. In comparison, patents are protected by the state and have a stronger legal status.
Considering the cooperation mode between Xu You and Luo Wenkun, applying for a patent is still a better choice.
"Teacher Cui, patent writing is still very difficult to handle. It requires both expressing the necessary information and keeping the core technology confidential."
"Okay, Mr. Xu, I will handle . I will show it to you after I finish writing it."
After arranging this work, Xu You did not work on other projects, but continued to study this material.
There is still room for improvement in the material preparation process.
During the first successful preparation process, the growth rate of the material grains was a bit slow.
If we want to achieve a mature processing technology, the growth rate of the material grains must be as fast as possible.
After Xu You and several teachers set a time, they gathered again in the materials laboratory and began to experiment with the optimization plan for material preparation.
"This time, we added parallel substrates to the reaction chamber, which can theoretically increase the growth rate of grains. At the same time, the requirements for the environment are more stringent this time, and we must control various environmental parameters more precisely."
Parameters including but not limited to deposition temperature, deposition pressure, reactant concentration ratio, reaction gas and carrier gas concentration, flow ratio, flow rate, etc. must be strictly controlled.
This is still very difficult for an experiment in the exploratory stage.
Sure enough, this experiment did not go as smoothly as the last one.
After the first day, they were unable to control the environmental conditions well and failed to generate the ideal grains.
However, after summarizing their experience, everyone finally found a better way to control 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 material preparation more efficient.
These harsh environmental factors will not be a big problem once the preparation process is mastered.
Overall, this is definitely a better cathode material for lithium batteries.
After completing the writing of the patent, Cui Ying gave the first draft to Xu You for review.
Cui Ying's patent was very well written. It not only met all the requirements of the patent, but also retained the core secrets of this technology to the greatest extent.
"Okay, no big problem, just apply . Also, please help me contact Luo Wenkun so I can talk to him about the use of the patent."
"Okay, Mr. Xu."
In the evening, Luo Wenkun came to Xu You's office.
"Xu You, has there been any breakthrough in the research?" Luo Wenkun asked excitedly.
"Well, this material is indeed very suitable for use as the positive electrode of lithium batteries. According to experimental test data, it can increase the overall energy density of the battery by 50%."
Hearing this news, Luo Wenkun became even more excited.
As the boss of Fulun Technology and a technology enthusiast, Luo Wenkun naturally knew what this meant.
"Great! For the next generation of Fulong mobile phone, I plan to make a thin and light version. This should be a very good selling point."
Currently, the battery capacity of mobile phones on the market is mostly around 4000mAh.
This amount of power is basically sufficient for daily use.
But such mobile phones often weigh more than 200g, or even half a pound.
There are some inconveniences in use and carrying.
Especially when playing with mobile phone while lying down, if you don’t hold it firmly, it may cause serious injuries to your face.
This is a common pain point in current mobile phones.
However, if you sacrifice the battery life of the phone to make it thin and light, you will face the problem of battery life and it will need to be charged frequently.
Therefore, improving the comprehensive energy density of the battery is the best option.
"Then why don't you consider making a longer-range version? With the same quality, the range will be 50% longer than before. I believe it will be favored by many users."
As mobile phone power becomes higher and higher, an increase in mobile phone battery level does not necessarily increase the screen-on time.
Having a mobile phone with a long battery life can greatly save you the trouble of frequent charging.
"Personally, I prefer thin and light models... well, I mean mobile phones. However, models with long battery life are also worth considering. We can do a vote on the Xueba community to see what everyone thinks. If the voting rates in both directions are 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 moment why Luo Wenkun had to explain specifically behind the thin and light version, but seeing that Luo Wenkun hadn't finished speaking, Xu You didn't rush to ask.
"Xu You, have you applied for this patent?"
"We are going through the application process. The core technology has been kept confidential. No one knows about it except me and a few teachers in the laboratory. The confidentiality agreement has been signed. Normally there won't be any problems."
To be on the safe side, Xu You did not communicate with anyone about some details of material preparation.
Even if those teachers were asked to repeat the experiments they prepared, it would be difficult to reproduce them.
"I am absolutely confident in your work. Once the patent application is approved, we can talk about cooperation. In order to ensure that the next generation of Fulong mobile phones can use this technology, we must speed up the research."
The positive electrode material of lithium batteries is the most critical technology of lithium batteries.
But that’s not all there is to lithium-ion batteries.
Several parts, including negative electrode materials, separators, and electrolytes, also need to be studied.
In addition to these, battery safety issues should never be ignored.
