When Ding Sheng designed the first version of the polymer battery, because the capacity was too small to move a complete set of battle armor, he didn't even make a semi-finished product, so he gave up directly.

But there is a good saying, the honey of A, the arsenic of B, now change the angle, bring out this set of plans to drive 3578-inch LCD screen mobile phones......

Oops, that's amazing.

"The third downward adjustment of the mobile phone battery for the transformation of the original polymer battery solution shows that the mainstream high-end mobile phones equipped with the battery solution can watch high-definition videos for 280 hours, the talk time is about 36 days, and the pure standby time is about one year... It is recommended to continue to reduce the battery capacity. ”

Although Ding Sheng was restrained enough to remove a part of the polymer material in the polymer battery, he did not expect the battery capacity to still be foul.

"Recording the fourth downward revision..."

On the test bench, he once again made a drastic transformation of the polymer battery in his hand.

Soon, a new polymer material polymer battery mobile version with moderate capacity, both safety and portability was officially released, according to Guan Ju's substitution into the fruit 4th generation simulation, and finally came to a charge can be 120 hours of video calls and standby for four months.

Polymer batteries are not a new concept, and the reason why they have not been widely used in the market is that there are indeed technical difficulties such as "electrolyte is difficult to purify" and "overcharge and overdischarge seriously affect battery life" that have not been overcome, and second, the problems that any new technology will face and the cost is high.

First of all, technology is not much of a problem for Ding Sheng.

As for cost savings......

If you want to make a product extremely good, then Ding Sheng is still on the road of transformation and climbing, but if you want to make a product worse, then he says second, and no parallel universe dares to say first.

No bragging.

Really too experienced.

The revised battery in Ding Sheng's hand is applied to the mobile phone, and the cost of a piece is about 500 yuan, of course, it is certainly not low, but if it can be mass-produced, the cost can be reduced by half.

Is it expensive to get two hundred and fifty dollars for a battery of this level?

Expensive!

It seems that I have vaguely heard someone say that it is expensive, so it is good to replace the limited polymer material in the battery with "polyvinylidene fluoride for homopolymer", and the cost can continue to fall.

All in all, Ding Sheng's battery is an insurmountable mountain for the current and even the next ten years of the mobile phone battery market, both in terms of technology and price.

"What companies are developing polymer batteries for mobile phones around the world?"

Knowing oneself and knowing one's opponent, Ding Sheng's products are very good, but after all, they are "civilians" who came out of a small workshop, and if they want to compete with the "gate valve" in the market, there is a long way to go, and they need more strategies.

He has a deep understanding of this at Marvel.

"Nook Kee, Fruit, and Samsang have all set up relevant R&D departments, but none of them have any practical effect. At present, the deepest progress is Sony, leaving only two difficulties in cost and volume control. Of course, even if we conquer it, the capacity is not the same as our product. ”

Guan Ju went around the network, and the firewalls of most technology companies are useless to it, and as for the remaining part, there is indeed something, not to mention for the time being.

"Then, do you need to apply for a visa to go abroad next?" Guan Ju asked very humanely.

It is true that most of the companies that need this kind of black technology battery are concentrated abroad, and Ding Sheng inevitably has to make a trip in person, but he doesn't want to move.

"Write two product introductions of the new polymer material polymer battery and send them to the CEO mailbox of Nokian and Fruit Company respectively, and then wait for the news. ”

Selling things, in principle, of course, is the one with the highest price, but Ding Sheng doesn't want his products to fall into the hands of some unscrupulous companies, so he still has to give full play to the Chinese tradition, release a little news to prove that he is a "Wolong", and then wait for people to "look at the thatched house" is the best policy.

It's just that this strategy has a hard flaw, and it will be embarrassing if no one shows up for a long time.

"What about Sansang? Their company also has the strength to bid. Guan Ju asked.

"No, the universe is theirs, presumably they already have the power gem, and they won't need this kind of small-capacity battery. Ding Sheng replied casually.

“... This meme is funny. ”

Backed by a global network, there is no joke that Guan Ju can't understand.

"That's right....."

When an elderly man wearing a T-shirt and jeans checked his mailbox, he found an all-Chinese email, the Chinese characters were too complicated for him to read, but the picture was easy to identify, and it seemed to be related to the battery, so he called the assistant, "Does the company have employees who are proficient in Chinese?"

"Yes, I'll arrange it right away. ”

Three hours later.

"Is it theoretically possible to implement the technology mentioned in this email?" asked the T-shirt man.

Theoretically?

The surrounding technicians fell into deep thought, and the leading technical director had to bite the bullet and say, "Yes, but with Huaxia's technical reserves, it is impossible to develop such a level of battery so many years ahead." ”

"Could it be that they copied Sony? Huaxia's copycat ability is super powerful. "A technician who doesn't know the ball is just talking.

"Sony is indeed the leader in the field of polymer batteries at the moment, but their products are nowhere near as exaggerated, and this email, while self-justifying, avoids all important technical issues, and I'm sure it's a prank. "They all eat this bowl of rice, and the technical director even dares to guarantee the job.

This time the man in the T-shirt fell into deep thought.

He is a perfectionist, and the fruit 4 released the other day can be said to be his brainchild, which is excellent, but not perfect.

The most direct heart problem is the battery capacity, compared with the standby time of more than ten days in the previous feature phones, the fruit 4 has to be charged almost every day.

If there is such a battery, a wave must be considered.

"Cook, what do you think?" the man in the T-shirt turned to look at another man who was five years younger than himself, and when he left, he would lead the company forward.

It's good to be young.

"First of all, battery technology is a global shortcoming, and our fruit 4 is good enough to worry about it. However, because of this, if the technology is real, it is not good for other companies to get it. So I think whether it's true or not, you can take a trip to this... LinZhou。 ”

Cook is different from his old leader, he is a businessman in the true sense of the word, in business, mercenary, technology is not updated is not important, as long as competitors are not updated.

"Okay, I'll take a trip. "The T-shirt man clapped.

"Your body is not suitable for long journeys, so let me go this time. Cook stood up.

"It's fine. ”

"That's right......"

When the CEO checked his mailbox, he also found an all-Chinese email, the Chinese characters were too complicated, he couldn't read it, but the picture was easy to identify, it seemed to be related to the battery, so he stopped the assistant, "Does the company have employees who are proficient in Chinese?"

"Nope. ”

"Okay, it's okay, you go down. ”

I clicked delete casually, turned off the phone and got off work, Mr. Nuo Kee stretched his waist, and it was another busy day.
