Chapter 112 My Parents Are the Villains 24
"Mom, don't be afraid, it's a good thing!"
Xiao Xiao nestled on her mother's shoulder and whispered comforting words in her ear.
Ge Shihui felt a little relieved, but she still felt inexplicably nervous.
As soon as the group entered the factory manager's office, the talking inside immediately stopped, and the atmosphere changed.
"Sir, the person has been safely delivered."
After the two soldiers saluted a soldier inside the room, they closed the door and left.
Everyone in the room turned their attention to the little bean sprout in Ge Shihui's arms.
Ge Shihui froze instantly, looking at the room full of high-ranking officials, standing there somewhat at a loss.
Xiao Xiao patted her mother's shoulder, signaling her to put her down.
After Xiaoxiao landed, Factory Director Nie walked up with a smile, pointed at her, and introduced her to everyone:
"Professor Chen, leaders, this is our factory's little prodigy, Comrade Feng Xiaoxiao."
Professor Chen excitedly sat up from the sofa, walked over to Xiao Xiao, and looked her up and down with surprise.
This little girl is so tiny!
She's three years old! Wow! Such a big face, truly striking features.
His eyes were dark and bright, sparkling with light and full of spirit.
He looks like a smart kid.
He bent down, touched the little head, and smiled kindly.
"Child, tell your uncle, how did you come up with the idea of using lithium cobalt oxide and graphite as the cathode and anode of the battery?"
"Uncle, I made a remote-controlled paper airplane, but it can't fly far because the battery is not powerful enough."
I wanted to improve the current nickel-cadmium batteries, so I consulted a lot of information and books.
I found that the resistivity of nickel is 15.7 x 10⁻⁶ W·m, while that of cadmium is around 7.8 x 10⁻⁶ W·m.
The higher the resistivity, the greater the battery loss during charging and discharging.
而锂的电阻率只有约为10.8x10??w·m，石墨的电阻率约为(8～13)x10??w·m
Using them as battery electrodes can reduce the battery's internal resistance and improve charging and discharging efficiency.
Professor Chen smiled and nodded; these were familiar to him. He took the child's hand and sat down beside him on the sofa, then continued to ask:
"But graphite's resistivity isn't superior to cadmium's, is it?"
Xiao Xiao found it difficult to sit on the sofa and talk to the old man with her head tilted to the side, so she simply slid off.
The little girl leaned against the tea table and explained to the old man in a childish voice:
"But graphite has a different structure; it has a layered structure."
It provides a good conduction channel for lithium-ion insertion and extraction, ensuring the battery's charge and discharge performance.
Professor Chen's eyes widened; he knew that graphite and lithium compounds had a layered structure.
This was the first time he had ever heard of the idea that this structure could be linked to the oxidation reaction mechanism of a battery.
He pressed on with a look of surprise and uncertainty:
"I've looked at the chemical reaction formulas you wrote; just from that perspective..."
Its mechanism for converting electrical energy into chemical energy is the same as that of the redox reaction produced during the charging and discharging of nickel-cadmium batteries.
This is far from the energy density you mentioned.
"No, they are different. Lithium-ion batteries use the process of lithium ions being inserted and extracted into the positive and negative electrode materials to carry out redox reactions."
Nickel-cadmium batteries achieve energy conversion through the redox reaction between cadmium and nickel hydroxide.
The electrode materials and reaction processes of the two types of batteries are different.
"Does it make any difference?"
"Yes, the chemical reaction mechanisms are different... In short, this kind of intercalation and deintercalation reaction..."
It can store more energy with the same volume and mass.
This is why its energy density is five times that of a nickel-cadmium battery.
My mouth is dry and I'm a little tired from writing this short story.
She picked up her teacup and drank it in large gulps, seemingly oblivious to everyone else.
The meeting room was quiet except for the soft gurgling sound of someone drinking water.
Professor Chen took notes and pondered as he held a pen and paper.
The young man next to them was also writing furiously, quickly recording the content of their conversation.
He had a premonition that a major scientific achievement was about to be made.
He is both a witness and a participant in the future.
This excited him so much that his hand trembled as he wrote.
Ge Shihui and Feng Yimin stood in the corner, watching their child chatter away with the elderly man across from them, who wore glasses and had gray hair, exchanging questions and answers.
The daughter was just as good as the boy, and even had the upper hand from beginning to end.
At first, the old man was full of doubts, but the more he listened, the more shocked his expression became.
In the end, I simply started taking notes of my daughter's words like a primary school student.
This reminded Ge Shihui of the Little Sunflower Classroom in the evenings; she was always like this when class started.
The couple were deeply shocked, a feeling that defies description.
The two of them didn't dare to breathe.
Not only them, but everyone else also held their breath and stood still.
I watched the two of them, one big and one small, talking and interacting the whole time.
Xiao Xiao would pick up her teacup and drink whenever she was thirsty, and someone would proactively refill her teacup after she finished.
Feng Yimin glanced at the leader pouring tea; this person seemed to be Director Han from the city's Revolutionary Committee.
His heart skipped a beat. Good heavens, his daughter is really...
The daughter, however, didn't even glance at him, oblivious to everyone around her, her little mouth still chattering away.
When she got hungry, she took out a White Rabbit candy from her pocket, tore open the wrapper, and took a bite.
He answered the old man's questions while chewing on a milk candy and spitting out saliva.
Surrounded by a group of high-ranking officials, he looked extremely comfortable.
He took the opportunity to turn his head and exchange a glance with his wife, and they both saw the shock in each other's eyes.
From beginning to end, the couple couldn't understand what their daughter and the old man were saying.
Listening to it is like listening to gibberish.
But that doesn't stop the couple from feeling proud and honored.
Look! A child prodigy, my daughter, the one I gave birth to.
The awkwardness and tension they felt when they entered completely vanished by now.
Two hours passed, and it was completely dark outside. Little Xiao's stomach started growling.
The old man heard this, suddenly realized what was happening, and looked at Xiao Xiao with embarrassment, saying:
"Oh dear, it's all the old man's fault for starving our little prodigy."
As he spoke, he looked up at Director Luo, who had accompanied him from the provincial capital.
Director Luo smiled, but before he could speak, Factory Director Nie hurriedly said with a smile:
"Professor Chen and all the leaders, please try the food from our machinery factory tonight. I've already had it prepared. Please enjoy!"
Everyone laughed and stood up. Professor Chen tried to pull Xiao Xiao along, but Xiao Xiao turned and ran towards Ge Shihui at the back of the crowd.
"mom!"
Ge Shihui immediately picked up her daughter, disregarding the presence of so many people, and kissed her daughter's big face twice.
Little Xiao giggled and hugged Ge Shihui's neck, whispering in her ear:
"Mom, aren't I amazing?!"
"Amazing, amazing, my daughter is the best."
