Spacey stood on the podium and looked around the room, a satisfied smile on his face. Sure enough, as he expected, there was no uniform array of suits of the members of the Fang group 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 lithium water battery is undoubtedly a major positive for the market of secondary rechargeable batteries, and provides a clear and feasible direction for lithium-ion charging technology.

As the "American inventor" of this technology

Spacey did receive countless applause and flowers.

The American Dream has never emphasized fairness, hard work, and hard work, but rather the idea of seizing opportunities, and elements like the legendary lucky boy 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 is now rich and has a new real room invested by large companies, so no one will question his approach, and there will be no mainstream criticism.

Therefore, now Spacey is standing on the podium of the opening ceremony of IBA - "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. And our water lithium battery products will be a revolutionary technology. It perfectly solves the safety hazards of lithium metal batteries, and the energy density is quite higher than that of nickel-metal hydride nickel-cadmium batteries, and it is foreseeable that water lithium batteries will be widely used in all mobile electronic devices in the future. ”

"Motorola's mobile phones are already working to improve their battery systems, preparing to use a large number of aqueous lithium-ion batteries, which will greatly increase the service time of its 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 no choice.

Who let him take the money of the capitalists, the festival of scientists or something.

I had to throw it on 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 requires scientists who dare to stand on the podium to have a strong confidence in their 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.

The theoretical basis of lithium-ion secondary batteries can form the peripheral technology of products, Spacey is like a student who copied the answer to the exam, and hurriedly memorized the problem-solving process in order to cope with his parents after the exam.

But behind this problem-solving process.

What is the idea behind 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.

So, how dare he really let the scientists below ask random questions?

It's as if the Chinese liars have a "trust"

In the same way, Americans are not White Lotus, and who wouldn't 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.

Nevertheless.

But the performance of lithium water battery is obviously really 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 of the scientists in the room were also beginning to be visibly dissatisfied.

Because the level of these questions is relatively limited, it is completely unable 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 it!"

Mao Qingzhu slapped his palm.

Nodding and saying, "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 heavily 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's eyes swept over the audience, and then he pointed to Ling Xiao: "This Chinese gentleman, please ask a question." ”

“hatf――！”

Spacey swallowed the expletives back into his stomach and stood up with a shuffle.

What the hell is this!

Why are there Chinese in the venue?

Didn't the Chinese group of members be blocked out of the venue by him?

It's 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.

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—"

It is impossible for Spacey to lie on this issue, otherwise he will not be the only one who will be bankrupt when the product is launched, and he will 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 flash of genius for more than a decade or so could not be raised in a hurry.

Therefore, it is conceivable that the design scheme of Motorola's water lithium battery products is based on existing technologies and the use of various "stupid methods"

to solve.

For example, when it comes to limiting voltage, Motorola uses the only way it can think of, which is to control the charging and discharging voltage through the guò circuit not exceeding 1.5V.

However, "So let me ask you a question, what if the lithium water battery is misused, or if 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. ”
