In addition to these relatively large problems, there are some relatively small problems, because it is the first time to make batteries, obviously not so easy to succeed, so during this time, except for occasional school classes, he basically devoted his time to research, and the lights in the laboratory were bright all night.

In this way, I was busy for about a week!

Anfeng City, Chengdong Community, Star Laboratory.

"Bang!"

A slight explosion suddenly sounded, and a thick plume of black smoke quickly rose from the laboratory.

Xie Dong sat on the sofa with a tired face, stretched out his hand and rubbed his face, feeling a little unwilling.

As a result of the explosion just now, his hair was like a chicken nest, messy, his arms were also covered with carbon black, and he was covered in filth, and the white coat on his body was even more black and white, as if he were a beggar, embarrassed.

"The data monitoring is complete, the lithium ion loses its activity, and it fails!" Vicky's voice rang out.

"It's already the thirty-fifth defeat!"

"Got it, good record!"

"Okay!"

After speaking, Xie Dong seemed to be paralyzed, lying on the sofa in the laboratory, reaching out and rubbing his forehead vigorously, his face full of pain.

Just when the battery exploded, he was shocked, and a plastic bottle flew up and hit his forehead, making him feel a little pain.

If it weren't for the fact that his body was different from ordinary people, I am afraid that he would have been smashed just now.

The so-called graphene battery, in the final analysis, is a new energy battery developed by using the characteristics of lithium ions to quickly and massively shuttle between the graphene surface and the electrode.

Although this kind of battery has a relatively high technology content, in the final analysis, it is also inseparable from the characteristics of some ordinary batteries, such as electrolyte, lithium-ion, large single crystal ternary electrode, etc.

Due to the high requirements at the beginning, it is inevitable that various hazards will be encountered during the manufacturing process, such as sudden explosions during charging.

Although the degree of the explosion is not very high, if it comes suddenly, it is actually quite painful.

The most important thing is that having tried thirty-five consecutive failed attempts, the direction I chose at the beginning, it seems that there is some kind of deviation.

It seems that some corrections need to be made.

"Failed again?" At this moment, the door of the laboratory was suddenly pushed open, and a shadow hurriedly walked in.

It is estimated that she has just finished school, and she is still carrying her schoolbag, looking a little nervous, probably hearing the explosion just now.

"yes!" Xie Dong glanced at her helplessly, picked up the kettle and poured a glass of water to drink, planning to try another direction again later.

Seeing that he was in a state of embarrassment, Mu Lingshan hurriedly walked over with a worried face and asked, "How did you become like this?" Brother Dongzi, are you okay? ”

Xie Dong looked up at her and said with a relaxed smile: "It's okay for the time being, it's just that it's stained with some filth, and the necessary failure is not negligible!" ”

Mu Lingshan saw that his forehead was a little red and swollen, and said with a distressed face: "My forehead is swollen, and I said it's okay, I'll go get the potion and come over to help you wipe it!" ”

As he spoke, he hurried towards the cabinet.

Xie Dong looked at her and smiled slightly: "Dabai has already checked it for me just now, it's really fine, it's just a wipe!" ”

Mu Lingshan took out the potion and rubbed it for him, while sighing faintly: "Alas, I knew that this battery must be difficult." I've been busy for so long, and I still don't have a clue, and I don't know how much time it will take. When Dongzige developed smart terminals, he didn't spend so much energy. ”

Xie Dong raised his hand and gently tapped her head and said: "The smart terminals are all ready-made, and they are also in the field I am good at, so naturally there is no problem, but the battery, I am doing it for the first time, and I don't know anything before, and it is completely black." Failure is a matter of course! ”

Mu Lingshan gently rubbed his forehead, blew on the aroma, and sighed: "In short, during this time, Brother Dongzi has always made people a little uneasy, I didn't expect this battery to explode, it's too dangerous." ”

"It's overheating!" Xie Dong emphasized.

Mu Lingshan immediately raised her head, and said with a resentful expression: "I don't care if it's too hot or too cold, in short, it's just not at ease!" ”

This girl, with a puffed appearance, is like a deep resentful woman, full of complaints.

Since Xie Dong did research behind closed doors during this period of time and did not continue to go to class with her, she was quite unhappy.

Xie Dong smiled speechlessly, didn't mess with her, and asked, "Speaking of which, I'm a little hungry, did you bring something?" ”

Mu Lingshan nodded and said, "I brought it, but your hand-" She sighed faintly and continued: "You wait a while, I'll go and bring a basin of water to help you wash it, this is all a beggar." ”

Xie Dong looked at his hands and said with a smile: "No need, I think it's good." ”

"Wash your face!"

Mu Lingshan glared, seeing that he was embarrassed, he felt uncomfortable, and he didn't care about him, he quickly walked towards the bathroom, and it didn't take long for him to come back with a basin of water.

Xie Dong looked at her and couldn't help but feel a little speechless, he didn't expect this girl to become gentle.

You know, she used to be heartless.

"How long will it take to be busy this time?" Mu Lingshan asked as she washed her hands.

Xie Dong thought for a while, sighed and said, "I don't know yet, this road doesn't work, and I may need to try another way." The biggest advantage of doing so many experiments is that at least some of the failed methods are eliminated, and the rest is much simpler. ”

Mu Lingshan frowned and asked, "Isn't Vicky able to simulate it too?" ”

Xie Dong shook his head: "It's a bit difficult, because it's brand new, and her database lacks this information." ”

Mu Lingshan was silent for a moment, then sighed faintly, wrung out the towel, wiped his cheeks, and said, "Brother Dongzi, I think I'm more like your nanny now!" ”

"Oh? How so? Xie Dong was surprised.

Mu Lingshan looked at him and suddenly smiled slightly: "Look, I'll wipe your face again, wipe your hands again, and bring you delicious food, all-round protection, what is not a nanny?" I feel like I'm just a babysitter. ”

Xie Dong was choked by her strange thought, and immediately laughed: "Hehe, if you don't like it, you can not do it, and no one forces you!" ”

Mu Lingshan smiled slightly: "But, I like it!" ”

"Huh!" Xie Dong was stunned for a moment.

"Well, I just like it!" She added, Ying Ying smiled, picked up a towel and wiped it lightly on his face, blushing and a little shy: "I've been liking it for more than ten years." ”

Xie Dong was choked again, thought about it, and said with a smile: "Your confession is a bit different, it's quite creative!" Who did you learn from? ”

Mu Lingshan glanced at him with an unhappy face and said, "Don't be cheap, and be good!" Today I discussed it with Nian Lei, and they said that your situation belongs to one of the scumbags. And the very, very scum kind! They told me to stay away from you, or I would suffer sooner or later! ”

Xie Dong was stunned: "Scumbag? ”

"Hmmm! Scumbag! Mu Lingshan nodded and smiled, blinked a little mischievously, suddenly came over, kissed him lightly on the lips, and then said with a smile in his eyes: "Because until now, you haven't recognized me as your girlfriend!" (To be continued.) )
