Spacey stood on the podium and looked around the room, a satisfied smile on his face. Sure enough, as he expected, there was no neat array of suits for the Chinese members in the venue.

If the technology of lithium water battery is not complicated, a positive electrode composed of lithium manganese oxide is placed in a neutral mixed solution of lithium nitrate and lithium sulfate, which can store electricity.

But the problem is that the electrolyte uses an aqueous solution, so this thing is slightly dangerous when charging and discharging. If the voltage is a little higher, the aqueous solution is electrolyzed into hydrogen and oxygen, and then ignited by a short circuit - I am afraid that everyone who uses a mobile phone does not want this to happen to themselves, right?

There is a premise for the safety of lithium battery, that is, the voltage must be limited to about 1.5V, and it will be dangerous if it exceeds 1.8V. And because the voltage cannot be high, its energy density and its cost performance are not qualitatively improved compared with similar products in the world.

However, in any case, the emergence of water lithium battery is undoubtedly a major positive for the market of secondary rechargeable batteries, and provides a clear feasible direction for lithium-ion charging technology.

As the "American inventor" of this technology, Spacey did receive countless applause and flowers. The American Dream of the United States has never emphasized such things as justice, hard work, and hard work, but rather the elements of seizing opportunities, legends, and lucky boys are more popular.

Spacey was the first to realize the prospect of water lithium battery technology, and the first to register a patent for water lithium battery in the United States, which is the American dream.

The important thing is that Spacey is now a successful person, and the important thing is that Spacey now has the money and the new labs that big companies have invested in. So no one will question his approach. There will be no mainstream criticism either.

So. Now Spacey is on the podium of the IBA's opening ceremony -

"As we all know, the safety problem of lithium metal batteries is relatively large, but lithium, as the metal with the greatest energy storage potential, has never been abandoned by the secondary rechargeable battery market. Our lithium battery products will be a revolutionary technology, which perfectly solves the safety hazards of lithium metal batteries, and the energy density is quite higher than that of nickel-metal hydride and nickel-cadmium batteries, and it is foreseeable that in the future, lithium water batteries will be widely used in all mobile electronic equipment. ”

"Motorola's mobile phones are already working to improve their own battery systems. Prepare a large number of aqueous lithium-ion batteries, which will greatly increase the service life of their mobile phones and reduce considerable weight, which will inevitably lay a solid foundation and decisive role for the success of Motorola's products in the market!"

Spacey's speech ended with an advertisement for Motorola, which was also helpless, who let him take the money of the capitalists, the discipline of the scientists, or something, had to be thrown to the ground first.

However, the scientists present did not let him go, and soon some people began to raise their hands to ask questions.

The Q&A session after the speech is the standard configuration of academic conferences, and if anyone dares to cancel the Q&A session after the speech, I am afraid that they will not be able to mix in the scientific research community in a minute.

This also requires scientists who dare to stand on the podium. You must have a strong confidence in your own technology.

But the crux of the matter is that the water lithium battery technology is not Spacey's own technology.

Although he has made quite in-depth research on lithium water, he is only in the process of understanding at most. Theoretical basis of lithium-ion rechargeable batteries. The peripheral technology that can form the product, Spacey is like a student who copied the answer to the exam, and after the exam, in order to cope with the parents, he hurriedly memorized the problem-solving process.

But behind this problem-solving process, what is the idea of this process? How is its theorem proved? Is there a more convenient way to solve the problem besides this approach?

He didn't know anything.

Therefore, how dare he really let the scientists below ask questions casually? Just as the Chinese liars have a "trust", and the Americans are not white lotuses, who would not be able to cheat.

With the face of Motorola, the following people have already been arranged to ask questions.

The first two questions can be chosen by Spacey, and he rightly points to two predetermined relationships, and sure enough, the other party asks two relatively simple and touting questions.

Despite this, the performance of lithium water battery is obviously very good, and it has also won him a little applause.

And the next question is not chosen by Spacey himself, but assigned by the host.

But it doesn't matter, the host has actually been bought by Motorola a long time ago.

Ling Xiao raised his hand several times in a row, but unfortunately the result was completely ignored by the host. Some scientists in the venue also began to be obviously dissatisfied, because the level of these questions was relatively limited, and it was completely impossible to meet everyone's expectations and understanding of water lithium battery.

"Hey, Professor Ling, how is your English?" Mao Qingzhu suddenly touched Ling Xiao's arm and asked in a low voice.

"I'm good at English, my father studied in the United States and taught me English since I was a child. ”

"That's fine!" Mao Qingzhu clapped his palms and nodded: "Raise your hand for the next question, can you help me translate the question I asked in Chinese into English?"

"Okay, no problem. However, it seems that the host ......"

"That's the next one, not me. Mao Qingzhu smiled, and it happened that at this time Spacey finished the last question, and the host began to ask everyone to raise their hands to ask questions.

"Raise your hand!" Mao Qingzhu put his hand on Ling Xiao's elbow and raised his hand high.

At the same time, his gaze met that of the host and nodded slightly.

"The next questioner—" The host swept his eyes around the room, and then pointed at Ling Xiao: "This Chinese gentleman, please ask a question." ”

“whatf――！”

Spacey swallowed the dirty words back into his stomach and watched Ling Xiao stand up.

What the hell is this! Why are there still Chinese in the venue? Wasn't the Chinese group blocked out of the venue by him? This is not scientific!

Speaking of which, although IBA wants to sell Motorola face, the credibility of being an intermediary is very important, and even if it does, it can't be sold to Spacey so cheaply, right?

Organizing such an academic conference is a little bit more than a few hundred thousand dollars, and Motorola's face is that Spacey arranges an opening speech, and cheating to ask questions is going to make money. But unless Motorola can barely make up for the brand loss and long-term losses caused by IBA for a few million, how can it completely fall to Motorola?

If you really want to do this, then it is better for Motorola to hold an academic conference on its own.

What's more, Spacey is standing behind Motorola, but behind Mao Qingzhu there is Grumman Aerospace, how can this be compared!

"I have a question about the safety of lithium water battery, I would like to ask Professor Spacey, if the battery charging and discharging voltage exceeds 1.8V, how to ensure that the aqueous solution is not electrolyzed in this state?"

Mao Qingzhu's question echoed in the venue through Ling Xiao's translation.

Many scientists sat up straight and realized that the meal had finally begun. The electrolysis problem of lithium water battery is indeed the biggest problem hindering its application.

"Well, Motorola's water lithium battery is designed with sufficient safety measures, so there is no need to worry about the possibility of water electrolysis. ”

"What are the security measures?"

"I'm sorry, it's a trade secret. ”

"After Motorola's lithium battery products are put on the market, will they also use trade secrets to answer the user's right to know?"

Spacey had no choice but to bite the bullet and say, "Motorola's products will provide protection circuits to stop the possibility of voltage increases. ”

However, in the previous life, on the polymer lithium-ion battery, which was used under relatively less harsh conditions, it was extremely difficult for Hu Wenhai to design a protection circuit, not to mention the low voltage of only 1.5V water lithium battery.

No matter how great Motorola's ability is, it is impossible to come up with a sufficiently complete protection circuit in two months.

"Is your company's protection circuit in a mobile phone, or is it integrated into a water lithium battery?"

"This-" Spacey couldn't have lied on this issue, otherwise he would not be the only one who would have gone bankrupt when the product was launched, but he would have to pay Motorola.

"Our protection circuitry is made on mobile phones, but it's still safe......"

"That means we can't take the battery out there to charge it, and we can't use a charger made by a company other than Motorola to charge it?"

"Motorola's lithium water battery products are safe, and we have enough technical capabilities to ......"

Spacey is a chemist who studies rechargeable batteries, and Hu Wenhai's paper only introduces the water lithium battery technology itself, and he has never come up with his own complete product design plan.

Without this thing, if Motorola wants to put its products on the market, it can only design and explore it completely. Sometimes, however, a problem that was solved by an occasional genius in a decade or decades cannot be raised in a hurry.

Therefore, it is conceivable that the design scheme of Motorola's water lithium battery product is based on existing technology and the use of various "stupid methods" to solve it.

For example, Motorola used the only way it could think of the limiting voltage, which was to control the charging and discharging voltage through the circuit not to exceed 1.5V.

However,

"So let me ask a question, what if the water lithium battery is misused, or the protection circuit fails?"

Mao Qingzhu's eyes were a little blurry, and the scene of Hu Wenhai explaining water lithium battery technology to him appeared in front of him.

"You know, there's something in this world that's just a layer of window paper. Problems that are difficult to solve in one area may have mature solutions in another area. (To be continued......)
