Hearing this roar, Wang Hao immediately frowned. Pen & Fun & Pavilion www.biquge.info

What's the situation? Wasn't Wade already gone? What is this guy here for?

"Check it out." Wang Hao asked Li Xingyuan to push himself out of the laboratory, and soon saw the three guys in the room.

Among these three people, Wang Hao can be sure that he has never seen them, and for a while he is a little unclear about what these three guys are going to do.

"You are Wang Hao?" The man at the head circled around Wang Hao twice, and then said viciously: "It's because of you that we have lost more than 20 people?" Damn it! "This man has a beard, a big face and a thick neck, and his clothes are full of bullets, and the whole person looks very rough.

Seeing that he was about to start beating people as he spoke, Li Xingyuan hurriedly shouted on the side: "Wells, if you have something to say!" Mr. Wang Hao is now in a state of serious injury, you can't do it! ”

"I can't do it?!" Wells roared, "We've killed more than twenty of us to catch him, and you told me I couldn't even touch him?" ”

"You really can't do it," Wang Hao smiled and looked at Wells's eyes, and said: "My arms are now comminuted fractures, if you really can't recover me and can't write drawings by then, Wade is afraid that he won't be able to spare you." ”

"Stinky boy," Wells gasped for breath, then sat down on a tattered chair beside him, "Okay, then I'll spare you today." But I didn't come here for nothing today, you kid killed so many of us, I have to see if you have the ability! If not, Lao Tzu can collapse you now! ”

Kindness? This guy wants to see what we can do? What does that mean?

Wang Hao asked curiously: "I can't move my arms, what do you want to see if I have the ability?" ”

"That's simple," Wells snorted coldly, "I can't move my hand, isn't your mouth still there?" Today's request is very simple, you can't get high-end things now, low-end ones will always be there, right? From now on, you say what you need, these two brothers of mine can meet all your requirements, you can make me a Nanfu battery now! ”

Wang Hao: "......"

Damn, what did you just say? Nanfu battery?!

"You're talking about alkaline batteries, right?" Wang Hao suddenly laughed: "You mean that I said with my mouth, you are responsible for doing it, and then make an alkaline battery?" ”

"Yes, that's right!" Wells nodded fiercely: "Such a small question can't bother you, right?" He clapped his hands, and immediately someone brought in a soldering iron from outside, Wells looked hideous, and said, "I'll only give you two hours, if you can't get it, I'll burn you in one more minute!" Hehe, don't worry, Lao Tzu promises not to touch your arm! ”

It turned out that I just wanted to test us, this is simple.

Brother came into contact with this when he was tackling graphene high-energy lithium batteries in the laboratory, and if you want to stump us, it is absolutely impossible!

"Cheng, this is simple," Wang Hao nodded immediately, and said with a smile: "The reaction equation of alkaline batteries is Zn + MnO2 + H2O→ Mn(OH)2 + ZnO, and the electrolyte is potassium hydroxide. You just do that. ”

To say that what Wang Hao said was already very simple, but he didn't want the three of Wells to be confused, and he didn't understand what Wang Hao said at all.

"What are you doing in a daze?" Wang Hao said curiously: "Sitting here and deliberately wasting time?" ”

"The ......" Wells scratched his hair embarrassedly, smiled wryly, and said, "I don't quite understand, what is electrolyte?" ”

Wang Hao: "......"

Nima, you came here to test me, but you can't do it yourself?

"The electrolyte is the medium used by chemical batteries, providing ions for their proper operation and ensuring that the chemical reactions that occur during their operation are reversible." Wang Hao could only helplessly explain to them: "To put it simply, the alkaline battery can't work without an electrolyte, you understand this time, right?" ”

Wells continued to scratch his hair: "Still don't understand......"

"I don't understand this, you're going to take a?!" Wang Hao couldn't wait to kick his Ding Ding: "Then let me tell you a simple one, you know potassium hydroxide, right?" ”

Wells continued to scratch his head: "What's that?" ”

"Get out! Get out of here! Wang Hao's saliva sprayed on Wells's face: "You don't understand the electrolyte, and you don't know the potassium hydroxide, so how can TM tell me to make a battery for you?!" Roll as far as you want, change to a more understandable one! ”

"I ...... I ......" Wells was speechless by Wang Hao's scolding, ran out, and after a while, pulled another person in, and said, "He, he has learned something about this!" ”

"My name is Marko, please Mr. Wang Hao," Marco sat opposite Wang Hao and said, "You can tell me what you need, and I can guarantee that all your requirements and instructions will be met." ”

"Wouldn't this be the end of the long time ago," Wang Hao snorted and said, "Alkaline batteries use manganese dioxide as the positive electrode, zinc as the negative electrode, and potassium hydroxide as the electrolyte. Its characteristics are superior to those of carbon batteries, and the electric capacity is large. The chemical formula is: Zn+MnO2+H2O→Mn(OH)2+ZnO structure, understand? ”

"Well, I know all the ingredients," Marco nodded and said, "And then?" ”

"Then there is the electrode reaction formula," Wang Hao began to talk to Marko: "Positive cathode reaction: MnO2 + H2O + e-= MnO(OH) + OH-, MnO (OH) has a certain solubility in alkaline solution, MnO (OH) + H2O + OH-= Mn(OH) 4-, Mn(OH) 4-+e-=Mn(OH) 42-"

Marco began to sweat......

Wang Hao continued: "The negative electrode anode reaction: Zn+2OH-=Zn(OH)2+2e-, Zn(OH)2+2OH-=Zn(OH)42-, the total cell reaction is: Zn+MnO2+2H2O+4OH-=Mn(OH)42-+Zn(OH)42-, understand? ”

Marco Waterfall Khan thought for a long time, then shook his head and said, "No...... Didn't get ......"

"I don't understand how you're here to do it?!" Wang Hao squirted again: "Get out!" You two get out of here right now! Roll as far as you want! It's uncomfortable to look at you, you won't even run a fart, what kind of garlic do I have here?! ”

Wells and Marco ran out in the midst of Wang Hao's scolding, and the two of them didn't dare to stay at all because they had dragged 250,000 or 80,000 before......
