Polymer batteries, also known as lithium polymer batteries, are safer and have a higher energy density than ordinary lithium batteries.

You can do as much as you want, Ding Sheng was so poor that he had to rely on Chen Xu to help him with a cup of milk tea, and he thought about the cost of everything.

Now that I have money in my hand, the solution of "zero-cost solution to the instability of polymer batteries in high and low temperature environments" that has not been designed will be put on hold for the time being, and the finished product will be spent first, and then improved step by step.

Everything has a step-by-step process, and Super Serum 2.0 has also gone through dozens of revisions to have the effect that it will not produce side effects when taken in moderation after dilution.

Since the cost can be properly released, the problem is easy to solve, Ding Sheng independently designed a set of small thermostats, built into the polymer battery, and the job is done.

Of course, this is only temporary.

One problem is solved, and another problem comes out.

After the built-in thermostat, the internal space of the originally designed battery was very cramped, and a large part of the polymer materials needed in the main structure had no place to put it, and the original power was not enough, and now the situation has worsened.

What about increasing the size of the battery?

The first draft of Ding Sheng's design has reserved the battery volume to the maximum, and if it is enlarged, it is simply a pot on his chest, which is too ugly. Even if you engage in copycats, you can't not pay attention to the aesthetic effect at all.

What's more, in this world, he is a pioneer.

Fortunately, the mountain people have their own clever plans, and Ding Sheng changed the first draft as soon as he moved.

The original steel armor had the only power source built into the chest, and Ding Sheng added four small batteries to the four thrusters on his arms and legs.

In this way, the steel armor with the blessing of one large, four and five small batteries should be long enough.

The new design draft was quickly drawn, and just as he heard that the small mold factory in the industrial park outside the neighboring state was about to go out of business, Ding Sheng rushed to deliver charcoal in the snow.

"I can't do it. The owner of the mold factory shook his head when he looked at the drawings, "It's too fine, there are too many accessories and too miscellaneous, not only can we not do it, but with my experience in the industry for so many years, I can't do it anywhere." ”

Ding Sheng has actually omitted many details, just because he was worried that the mold factory would not be able to do it, but the reality still gave him a blow to the head.

Of course, he can also make his own equipment 1:1 imitation steel armor.

But at present, there is no such advanced equipment in the world, and if you want to get equipment, you have to get another set of equipment to build equipment.

And so on, in the end, eighty percent still found a mold factory to customize molds.

Let's talk about the cost, let's go down this set and smash 100 million first.

"What about this set?"

Ding Sheng had already prepared, according to the different precisions, he designed a total of many sets of drawings, and the one he came up with just now was the most precise set, and if it was rejected, he took out the second precise set.

"I can't do it. The boss took one look and continued to shake his head.

"What about this one?" Ding Sheng continued to concede.

"Little brother, you're a Transformer, you've seen too much, you can take the simplest set and I'll take a look. ”

The movie version of Iron Man is very marketable among young people in China, but for middle-aged people like the owner of the mold factory, maybe Transformers is their feelings.

Yes, Ding Sheng had no choice but to hand over a set of drawings with the lowest precision, this set can be said to be his bottom limit, basically all large steel plates, without many details.

"These places, these places, and these places can be adjusted, and you can do it. The boss pointed to several places with his fingers, not to mention that this person's eyes are really poisonous, and they are all critical.

"Boss, you're kidding. ”

After all, he still didn't understand the current level of industry, and he never thought that the worst set of designs would be considered too complicated. If you really change it according to the boss, then this set of steel armor will be almost the same as the model of a movie theater.

"I'm the only one left in this factory, I can only live on the county subsidy, I have to drink the northwest wind if there is no order this month, I still have the heart to joke with you?"

That's the big truth.

"Boss, I'm going to wear it on my body, these details are gone, and I don't want to wear it. Ding Sheng voiced his concerns.

"You can add a cotton pad. The boss replied casually.

Cotton?

Brother, you let me add cotton in the summer?

Ding Sheng shook his head directly, it seems that the plan is going to be shelved for the time being, and when there is time after the college entrance examination, go to the coastal areas to find a better foundry.

The boss is a human spirit, and he roughly guessed Ding Sheng's thoughts, "Little brother, the craftsmanship in the coastal areas is indeed better than that in the mainland, but they won't even let you in the factory gate for your set of orders." ”

After hearing this, Ding Sheng actually made a lot of sense.

"Actually, I can do your last set of drawings, but only one set, and I don't make money by doing it. In this way, if you place an order for five sets, I will help you do it, ......otherwise, "I still have a wife and children to support at home, it is a little difficult, and the boss is also very willing to put this list next."

Needless to say, Ding Sheng also knew what the boss said later, even if it was five sets, no one would pay attention to him when he went to the coast.

"You pay for the raw materials, use brand steel, how much is the five sets of assemblies?" There are banknotes in the bag, Ding Sheng is still very willing to use good materials, after all, he wears it himself. However, he suddenly increased the cost by five times, and he had no bottom in his heart.

"It's the most delicate job I've ever done...... The minimum is 12,000, one set. "The owner said a price.

Is it expensive?

It's not expensive, Iron Man's suit of armor is measured in billions.

Is it cheap?

It's not cheap, Ding Sheng used to think about building a battle armor with pocket money or something, but he really did it step by step, and he couldn't do it at all without money.

"How long can it be done?" This thing, the sooner the finished product, the better, the time drags on, maybe the second generation will come out.

"I'll do the first set as a model first, ten days. Four sets in the back, twenty days. "For the sake of life, the boss has nothing to fear.

"Okay, that's it. ”

After ten days, the college entrance examination is almost over, which is acceptable.

......

For students in the third year of high school, in June, it is the season of the college entrance examination, and the air is full of the smell of exams.

Ding Sheng has not been to the Internet café recently, except for the usual class time, he tries to soak in the laboratory to debug batteries, thrusters and induction devices.

Yes, there is no laser installation.

This thing Ding Sheng didn't consider installing it on the first-generation armor for the time being, mainly because it was too destructive, after all, it wasn't Marvel, and the power consumption was also high, and the three batteries he designed were estimated to last half a second?

In short, keep a low profile, and you shouldn't face an extreme situation where you need a laser device to save your life for a while.

June 4th.

"Ding Sheng, do you have something to do tomorrow?" Before school ended, Meng Xiao suddenly asked.

Two days later, the annual college entrance examination will be held, and the school will have a two-day holiday at this time, so that students can relax and rush to the examination room with the most relaxed attitude.

"Probably...... You okay. Ding Sheng originally planned to go to the mold factory tomorrow to take a look at the progress of the battle armor, but he couldn't talk to death, in case Meng Xiao needed help.

"We're going to the big Buddha temple in the south of the city to worship the Buddha, I heard that the new Buddha statue has just been painted with a golden body, and it is very big and effective, so you can come with it." Meng Xiao invited.

Every year before the college entrance examination, many students go there to seek Buddhism, which is not so much superstition as it is already a tradition.

"Good. ”

Ding Sheng vouched that he definitely agreed because of superstition, not because Meng Xiao was good-looking.
