Chapter 642: Chapter 642: Nickel-Hydrogen Batteries and Lithium Batteries
Jiang Changhai generously waved his hand, “What’s this? All the money I earn is going to be yours in the future, my girl. How about it? Isn’t the gold lock beautiful? I took quite a while to pick it out.”
“It’s beautiful, I really love it!” Jiang Mianmian nodded like pounding garlic, delightedly putting it around her neck.
“As long as you like it.”
Jiang Changhai smiled as well, patting her little head, “When you were born, we were poor and had nothing. Now that you’ve grown up, we didn’t even have a silver bracelet for you. I always thought about compensating you, making up for everything you missed out on tenfold, a hundredfold.”
“Dad, I think it’s great just for us to be together as a family. I’ve never felt like we missed out on anything.” Jiang Mianmian ran over from the bed to where her dad was sitting, flung herself onto him, and said with a giggle.
“Yes, it is great for us to be together as a family.” Jiang Changhai stood up, carrying his daughter on his back and wandering around the room, making Jiang Mianmian burst into laughter.
Su Wanyu let the father and daughter make a ruckus for a while before saying, “Alright, alright, stop fooling around, you two. Come to sleep quickly. We’ve got to work and go to school tomorrow.”
“My girl, your mom has spoken. Let’s go to sleep obediently.” Jiang Changhai put his daughter back in bed and waited until his wife and daughter were both lying down before he went to turn off the light.
As soon as Jiang Mianmian lay down, she entered the system space, leaving her external body to fall into a deep sleep state.
She intended to research how to increase the capacity of nickel-hydrogen batteries, after all, only by doing so could she reduce the cost of making cakes.
Once Jiang Mianmian entered the system, she excitedly said, “System, quickly help me find the materials about the production principle of nickel-hydrogen batteries. I need to see how to expand the capacity.”
Upon hearing this, the system brought out all the books related to nickel-hydrogen batteries.
System: “Host, I actually think you shouldn’t waste time researching nickel-hydrogen batteries. I suggest you directly make lithium batteries that are more sophisticated and durable than nickel-hydrogen batteries. Abroad, they’ve already got the technology to make lithium batteries. I’ll find you the books about lithium batteries from abroad, and you can see for yourself how to choose.”
After the system finished speaking, several thick files appeared in front of Jiang Mianmian.
Jiang Mianmian trusted the system, and since it recommended that she make lithium batteries, there must be good reason. She simply started reading through the information in the system right away.
The more she read, the more she realized that lithium batteries were better than nickel-hydrogen batteries.
Because lithium batteries have a longer cycle life than nickel-hydrogen batteries, which means under the same conditions, lithium batteries last longer than nickel-hydrogen batteries. They hold more electric energy per unit volume.
They are also lighter than nickel-hydrogen batteries, which makes them more convenient to carry.
The most important point is that the manufacturing and use of lithium batteries are more environmentally friendly, with no pollution, making them green environmental protection products, which gives them more advantages in development.
“So I’ll just make lithium batteries, increase the capacity a bit, and make them rechargeable. This way, the cost of making cakes will be greatly reduced,” Jiang Mianmian declared confidently.
Ever since Jiang Mianmian’s intelligence value reached the standards of a genius, she had become much more confident than before, especially since she relied on herself to research and develop the technology for color televisions, which gave her even more confidence.
Seeing her so enthusiastic, the system quickly encouraged her, “Host, you’re making the right decision. I believe you can definitely do it. Here, I’ll open the laboratory for you right now.”
After the system finished speaking, it directly deducted 1 intelligence point.
