Motorola's lithium water battery was originally intended to be integrated into a mobile phone, and it is forbidden to take out the lithium battery to charge it separately, so naturally there is no problem of misuse. The protection circuit itself also has a check circuit, if there is a problem with the protection circuit, you can stop the battery power supply.

However, how did Spacey say this to the people in the audience: The protection circuit plus the monitoring circuit and the voltage stabilization circuit can be used by the big brother who costs 3,000 dollars and weighs a kilogram.

If Spacey dares to tell the truth, the technology of this lithium battery will be exposed.

In other words, in the hands of Motorola, only they can use this thing, and other companies will definitely not pay for a technology that is not yet mature.

"Well, Motorola has a completely reliable solution to avoid misuse or circuit failure......"

Ling Xiao chased after Mao Qingzhu at Mao Qingzhu's signal: "What is the plan? Professor Spacey won't say what kind of trade secrets it is, right?"

"Of course not, as long as we wait for our products to be launched, everyone will know about them when the time comes. ”

"I guess the participants here won't be satisfied with such an answer, right?"

"I'm sorry sir, I don't want to answer your question anymore!"

Spacey has become angry, because he really has no good way to fundamentally solve the safety problem of water lithium battery. Being questioned by Ling Xiao like this, he had already begun to feel weak.

Ling Xiao pressed step by step: "May I ask if you don't want to answer, or can't you answer?"

"I don't ......" Spacey gritted his teeth and said with difficulty, "I don't want to answer your question!"

"Well, I'll answer that question myself. ”

Ling Xiao was surprised, he has been thinking about how to solve the safety problem of this battery after learning about the water lithium battery technology. However, I want to break my head. He couldn't think of a foolproof solution.

However, right now, Mao Qingzhu beside him actually asked him to say such a thing. Could it be that this little-known Xinke Battery Research Institute really has a military background? In fact, which advanced research institute of the domestic military industrial system? However, looking at the domestic and foreign style of the Xinke Battery Research Institute, no matter how you think about it, you can't link it with the state unit.

If nothing else, the foreign affairs department will never agree to this kind of insolent style of slapping the face in public. Even the research institutes of the military-industrial system. You also have to join a group when you go abroad.

Looking at Mao Qingzhu's performance, there is no trace of domestic leadership, and he is an individual nouveau riche.

But no matter how Ling Xiao turned the river and the sea in his heart, he still translated the content of Mao Qingzhu's prompt at the bottom.

"The problem is very simple, the safety hazard of water lithium battery comes from the electrolysis of water. Water expands in volume after electrolysis to produce hydrogen and oxygen, so as long as the battery is brittle...... encapsulated

Not only the scientists present, but even Ling Xiao himself showed an expression of sudden realization.

Water splits hydrogen and oxygen volume expansion, at this time if a brittle package is used in the inner layer of the battery. Naturally brittle materials will break when stressed. The battery package is broken, and the lithium cathode metal is out of contact with the battery sheath, and there is no danger of electrolysis if the circuit cannot be formed.

The brittle packaging technology is originally a secure packaging process used on high-power IGBT chips in the future, mainly referring to the ceramic packaging process, which is the preferred process for high-reliability packaging. Later, after Fudan University developed a new water lithium battery technology, it also considered using this method to package water lithium battery products, focusing on its safety.

So. The biggest water electrolysis safety problem of water lithium battery is solved. Correspondingly, Motorola has a stable circuit and a monitoring circuit. Not to mention the significant increase in cost, reliability is also very problematic.

And it is very unconscionable to say that brittle packaging will greatly increase the loss rate of water lithium battery batteries.

Capitalists never sell things that can be used for a hundred years, otherwise how to renew them, how to make people keep paying money, is it not a hammer deal?

So the most popular with capital. On the contrary, it is easy to break the product, and it is better to break it immediately after the warranty period! In this way, the businessmen can make the most profits.

This is exactly the case with brittle encapsulated lithium batteries, using inferior product chargers? No problem! Charging without following the instructions for use? No problem! Wrong operation during use? No problem!

Anyway, it's your user's own misoperation that causes damage, and it's time to replace it with a new one!

All you need is a businessman with a little brain. They all said that they were already laughing and crying in their hearts!

This kind of bad use or the user's own responsibility, rechargeable batteries into consumables good idea, this TM Chinese came up with ah!

Many people are already thinking in their hearts, whether it is time to sell genuine chargers more expensive, so that inferior chargers on the market are rampant, just to promote the consumption of lithium water!

……

Mao Qingzhu didn't know how Hu always thought of this "loss" idea, thanks to this is because most Chinese can't afford to use lithium battery rechargeable batteries, otherwise-

He didn't know that I was the last bastion of capitalism, and there would be many such things with no lower limit in the future. Hu Wenhai's little cleverness is just the wisdom of the Chinese people.

It's just that twenty years earlier, the people of the United States imperialism were invited to eat bread.

"The water lithium battery produced by Motorola uses this technology!"

No one thought that Spacey would brazenly shout such a sentence.

"This is Motorola's trade secret, how do you know? I want to call the police, you Chinese must have stolen Motorola's trade secrets!"

There was silence in the venue, and everyone looked at Spacey, who had gone crazy, in amazement, and could not imagine that he would dare to do it to such an extent.

"Oh, yes? But how does Professor Spacey explain that we have a patent for the brittle packaging technology of lithium water?"

"It's a conspiracy, it's a crime! I'm going to go to court to invalidate your patent!" Spacey was already gritting his teeth.

"Since Professor Spacey thinks that we stole Motorola's research, it means that you must know more about water lithium battery technology than us Chinese?"

Spacey kept his mouth shut, unaware of this, and instead instructed Martha, who was sitting in the front row, to go outside and call the police.

"If Professor Spacey doesn't say it, then I'll say it. In addition to lithium manganese oxide, we have also found another anode material, which can increase the energy density of lithium water battery at least three times at this stage. ”

As soon as Ling Xiao's words came out, the entire venue almost immediately burst into flames.

On the basis of the mainstream performance of the water lithium battery that is not inferior to the secondary rechargeable battery in the market, it will be improved by three times, then this is not an ordinary product upgrading, but a revolutionary progress of the secondary rechargeable battery.

Ling Xiao is not wrong in what he said, although he himself does not know, but in the future, the high-voltage version of the lithium water battery developed by Fudan University is claimed to have a level of 10000Wh/kg, which is better than the nickel-metal hydride battery. Of course, the moisture in this is estimated to be squeezed well to be believed.

But in any case, because the new water lithium battery in the future uses sodium ions and potassium ions as migration ions, it is absolutely no problem to conservatively estimate three times.

"If there is such material, then you name it. As long as I say it, I believe that you Chinese did not steal Motorola's technology, but developed it at the same time as us. ”

Spacey's eyes lit up, and he looked at Ling Xiao greedily, waiting for his mouth to spit out the mysterious and priceless negative electrode material.

However,

"Hehe, does Professor Spacey think I'll tell you this material again?" Ling Xiao smiled and shook his head: "In addition to improving the energy density of lithium water, we have also preliminarily mastered the way to increase the voltage of lithium water. ”

Spacey and all the people present secretly swallowed their saliva, and the water lithium battery, which greatly improves the energy density, solves the voltage problem again, which is really going to completely end the rhythm of the secondary rechargeable battery market.

"But in order to prove that what I said is true, I can generously tell you that a kind of anode material that can increase the energy density of lithium water battery by 20% is a by-product of our experiment. ”

"LiFeCoPO4, also known as lithium iron phosphate. It has better performance than lithium manganese oxide, but there are still some technical details that need to be worked out before it can be put into use. Ling Xiao's mouth spat out this word, if it weren't for the chemical formula, he wouldn't even know what it was.

Hearing Ling Xiao's words, everyone present smiled with satisfaction. The 20% increase in performance is already a good selling point. However, there was only one man with a dead face, and that was Spacey.

Because he knows that Motorola's desire to put into production of water lithium batteries may be in vain.

The reason is very simple, even if you infringe on the lithium iron phosphate battery, who knows when the Chinese will come up with the product that improves by 300%?

Even if you test the materials that increase by 300%, what should the Chinese do when they come up with water lithium batteries to solve the voltage problem? The experiment of these materials must require a large amount of scientific research investment, and the greater the investment, the greater the risk. Who dares to say that the Chinese must be bluffing, or maybe they have no fear? Judging from the material they generously provided lithium iron phosphate, I am afraid that the latter may be even greater.

I'm afraid Motorola wouldn't dare to take this risk. Once the product is put into production, the product with more advanced performance is put on the market, and the result is self-evident, and it will definitely be a disgrace and a big loss for Motorola.

Martha ran back from outside and whispered in Spacey's ear: "It has been found that the patent owner of the brittle packaging technology of liquid batteries belongs to a Chinese woman named yeqinxiao!"

"Yeqin Xiao, who is she, and why isn't she the previously found patent trap holder Wenhaihu?" (to be continued......)
