Not long after the harsh words left my office, I actually went directly to the Patent Office to get notarization.
Principal Zhou actually doesn¡¯t care much about things that affect him. For myself, it is certain that I will hold the position of principal until retirement.
¡°But this Huang Shaowen, Teacher Huang, is so impulsive, you should really talk to him carefully.
But unfortunately, Huang Shaowen stopped paying attention to Principal Zhou¡¯s interview. In view of Principal Zhou's attitude last time, Huang Shaowen had reason to believe that Principal Zhou's butt was sitting crooked.
Huang Shaowen even made it clear to the assistant who came to call him and asked him to go back, saying that he would not have any more conversations or contact with Principal Zhou.
The Patent Office told myself that the notarization still required some preliminary investigations, some procedures, and inviting relevant professionals, so Huang Shaowen was asked to wait for the time being.
Huang Shaowen had not done any notarization, or intellectual property notarization, and didn¡¯t know exactly what to do, so the patent office asked him to wait, and Huang Shaowen really waited first.
Principal Zhou was a little angry when he saw Huang Shaowen ignoring him. No matter what, he is still the principal of this school. Huang Shaowen is also an ordinary associate professor in this school.
Treating yourself like this is an act of disrespect for yourself.
"Since you have to wait for notarization, then just wait. It depends on how long you wait."
After waiting for a few days, Lin Yuqing sent over the foreign certificates and the contract between Star Airlines and the school. Huang Shaowen still didn't wait until when the notarization time was.
At this time, Huang Shaowen suddenly felt as if he had been tricked by someone from the patent office. Because Huang Shaowen was so familiar with this routine of asking others to wait slowly.
When I was the editor-in-chief of financial news, I often asked contributors to wait slowly. They thought they were really asking them to wait and would give them a result.
In fact, I just gave a casual and habitual answer, and if I waited, I would forget about them.
In the past two days, Huang Shaowen was so upset that he almost lost his mood to attend class. Fortunately, I can still control my emotions and understand that my own affairs should not affect the students.
While staying in the office on Friday, Huang Shaowen finally couldn't help complaining and wanted to go directly to the people at the patent office to ask them about their work efficiency and what their intentions were.
"Made, these people must be lying to me. I suspect that Principal Zhou's character has seriously deteriorated and he is suppressing me!" Generally speaking, Huang Shaowen would not make such unfounded speculations easily.
But now, based on his feeling, that¡¯s what he thinks.
"Don't hear this, Principal Zhou probably won't do such a thing. Maybe the process will take a while, and it should be fine next Monday." Li Jiahe comforted him.
I don¡¯t know if it¡¯s useful. Huang Shaowen indeed stopped talking after hearing this, but the expression on his face did not change for the better at all.
Just when he didn¡¯t know what to say, Liu Yiyang suddenly rushed in and said, ¡°Sony is here!¡±
Um? !
Huang Shaowen's vigilance was at its highest level. Why is Sony coming to our school at this time?
"I was in the cafeteria just now, guess who I met?" Liu Yiyang said suddenly and mysteriously.
Seeing that Huang Shaowen and Li Jiahe were not fighting, Liu Yiyang suddenly lost interest and curled his lips and said: "Shaowen, it has a lot to do with you. If you don't want to hear it, forget it."
"What is Sony here for? Come to buy my patent?" Huang Shaowen has probably already guessed a few things. After all, when I thought of making this battery, it was also because of Sony.
When Xiao Si wanted to buy a Walkman, Huang Shaowen thought about the battery.
When I decided to do this research, roughly counting the time, Sony also began to research new lithium-ion batteries. After all, their electronic products are now developing rapidly, and one of the biggest limitations is the battery.
The vast majority of ordinary people in this world don¡¯t really understand the quality of electronic products. What they want isn't really that good.
More importantly, the simplest one is whether this thing can be used and how long it can be used.
Compared with the lithium-ion battery successfully developed by Sony two or three years later, Huang Shaowen borrowed their graphite material and then replaced lithium cobalt oxide with lithium iron phosphate. It can be said that the battery performance is absolutely beyond this era.
When Huang Shaowen asked Lin Yuqing to register this patent in Japan, he told him to pay great attention to this point. Try your best and apply for this patent as quickly as possible.
Fortunately, the battery is not a particularly sophisticated thing yet. Therefore, it has not yet reached the level of close attention at the national level.
Although Sony is a big company, it is indeed paying attention to this development. But more of them are paying attention to international big names. Such as Mr. Goodenough. In contrast, they don't care so much about the Chinese people around them, and it's a patent document applied for by a foreign country in Japan.
Until, as usual, I found Japan¡¯s newly approved patent application for batteries. One of them is a new combined battery with lithium iron phosphate as the positive electrode and graphite as the negative electrode.
The aluminum foil is connected to the positive electrode of the battery, and the copper foil is connected to the negative electrode of the battery. A polymer separator is used in the middle to separate the positive electrode from the negative electrode, so that lithium ions can pass through the separator, but electrons cannot pass through the separator. The inside is filled with electrolyte, and the outside is sealed with a metal shell.
When the battery is charging, lithium ions migrate from the lithium iron phosphate crystal to the crystal surface. Under the action of the electric field force, they enter the electrolyte, then pass through the separator, and then migrate to the surface of the graphite crystal through the electrolyte, and then are embedded in the graphite lattice.
At the same time, electrons flow to the aluminum foil collector of the positive electrode through the conductor, flow to the copper foil collector of the negative electrode of the battery through the tab, battery positive post, external circuit, negative post, and negative tab, and then flow to the graphite negative electrode through the conductor. , so that the charge on the negative electrode reaches balance. After the lithium ions are deintercalated from the lithium iron phosphate, the lithium iron phosphate is converted into iron phosphate.
When the battery is discharged, lithium ions are deintercalated from the graphite crystal, enter the electrolyte, then pass through the separator, migrate to the surface of the lithium iron phosphate crystal through the electrolyte, and then re-embedded into the lithium iron phosphate lattice.
At the same time, electrons flow to the copper foil collector of the negative electrode through the conductor, flow to the aluminum foil collector of the positive electrode of the battery through the tab, negative pole of the battery, external circuit, positive pole, and tab, and then flow to the iron phosphate through the conductor. Lithium positive electrode balances the charge of the positive electrode. After lithium ions are embedded in the iron phosphate crystal, the iron phosphate is converted into lithium iron phosphate.
The service life of charge and discharge cycles generally reaches more than 2,000 times, or even more than 3,500 times. Far higher than the 300 times of ordinary lead-acid batteries.
Moreover, the electrochemical performance of the cathode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charge and discharge platform. Therefore, the structure of the battery will not change during the charge and discharge process, and it will not burn or explode, and even in short circuit, It is still very safe under special conditions such as overcharging, extrusion, and acupuncture.
