Apart from the redox of graphene, in this document, Xu Chuan keenly noticed another detail

In the reduction process of graphene oxide, because of the use of electrochemical reduction means.

The lithium in the lithium iron phosphate battery is reduced, and in the whole process, it combines with other substances produced by the reduction to form a lithium salt.

It was an unexpected achievement, but quite useful.

Aside from the reduction of graphene oxide, this achievement alone is enough to apply for a patent for the treatment of lithium phosphate batteries.

In fact, lithium battery recycling has always been a great problem.

Recycled batteries must be pretreated first, including discharging, dismantling, crushing, and sorting.

Although the disassembled plastic and metal casings can be recycled, there are many dangers involved in this process, not to mention the more troublesome waste liquid disposal in lithium batteries.

According to the current technical level, waste liquid treatment alone is enough to eat up the poor income of metal recycling.

Some people do U-turn business, but no one does loss-making business. It can be said that under the current technical conditions, few companies will take the initiative to invest in the lithium battery recycling industry.

The lithium battery recycling that can be seen on the market is basically derived from the policies of various countries. It can be said that if there is no subsidy or policy, the final destination of lithium batteries may only be the garbage dump.

Of course, if it's just like this, it can only be said that this is an extra surprise, and it hasn't been able to attract his attention.

What caught Xu Chuan's attention was that during the entire process, through the calculation of the experimental data of the material model, he noticed that the waste liquid of the lithium iron phosphate battery was first disassembled during the entire synthesis process, and then these mixtures produced The reaction produces carbon dioxide.

But in the whole electrochemical reduction process, carbon dioxide is not redundant, it participates in the reduction process of graphene oxide and lithium salt.

This is what really caught Xu Chuan's attention.

After spending some time, Xu Chuan read the entire document twice.

He didn't get up, and didn't speak, he thought about the office chair he was leaning against.

In the office, Master Xiong Fanpengyue, who had just boiled water and served tea, did not disturb him when he saw this, and sat quietly waiting.

The brewed tea was cold before Xu Chuan recovered from his contemplation.

On the opposite side, Fan Pengyue asked curiously: "What were you thinking just now? The tea is cold."

Hearing this, Xu Chuan said directly: "I wonder if there is any possibility of realizing a new technology."

Although this meeting has ended his thinking, he is still a little dazed, and all the remaining ideas in his mind have not dissipated.

"What new technology?"

Hearing this question, Xu Chuan finally came to his senses, smiled and said, "A technology that uses carbon dioxide to synthesize carbon compound materials."

Hearing this answer, Fan Pengyue was taken aback for a moment, and asked, "Why did you think of this?"

Reaching out to take the teacup from the table, Xu Chuan smiled and said, "I thought of it from the information I just read."

Hearing this, Fan Pengyue was stunned again: "Where?"

Taking a sip of the cooled tea, Xu Chuan continued: "During the electrochemical synthesis of graphene oxide and the reduction of graphene in the lithium iron phosphate battery, the oxygen in the lithium iron phosphate and the graphite in the negative electrode are separated by the current and the electrolyte. combined to form carbon dioxide."

"Theoretically, this carbon dioxide is not redundant, it may be involved in the reduction of graphene oxide or lithium salt."

"It got me thinking about repurposing carbon dioxide, and photosynthesis."

After a slight pause, he continued: "It is well known that plants and algae can synthesize carbon dioxide and water into energy-rich organic matter and release oxygen during photosynthesis."

"It mainly includes two stages of light reaction and dark reaction, involving important reaction steps such as light absorption, electron transfer, photophosphorylation, and carbon assimilation."

"Theoretically, this process can be completely replicated through experimental chemistry."

"And in this new electrochemical graphene preparation, I've seen at least two processes using carbon dioxide to synthesize relatively precious materials."

"So I was just thinking about whether the carbon dioxide in the air or other places can be collected and used again, and various carbon compounds and oxygen can be resynthesized."

"Carbon is the element that forms the most types of compounds. For example, gasoline, starch, glucose, silicon carbide, hydrocarbon, graphene, etc. are all carbon compounds or carbon materials. In theory, they can all be realized through technical means."

"If this method can be done, it may be able to solve various problems such as the greenhouse effect, the food crisis, and the shortage of raw materials."

After listening to Xu Chuan's explanation, Fan Pengyue was almost dumbfounded, and stared at him strangely.

He really couldn't figure out how the little junior in front of him could think of so many things.

Although graphene is indeed a carbon material, how can it be linked to the collection and reuse of carbon dioxide?

From graphene to the recycling of carbon dioxide

To be honest, he really wanted to open this little junior's brain to see what was inside.

Why does this structure feel different from ordinary people?

Xu Chuan didn't care about Fan Pengyue's weird eyes. After drinking a sip of tea, he asked, "Speaking of which, who thought of the method of reducing graphene oxide by electrochemistry?"

When he came back to his senses, Fan Pengyue said: "It's not someone who thought of it, but something calculated by the computational material model."

Hearing this answer, Xu Chuan was a little surprised, and asked curiously: "What is calculated by the computational material model?"

As for the models he made with his own hands, he is very clear about his abilities.

Unless the underlying logic and mathematics formulas are modified, it is impossible to do this step in a targeted manner.

The reason is simple, because he did not set up such a system in the underlying logic and mathematics formula.

Using the properties and mechanisms of materials to infer the possible chemical combinations of materials has gone beyond the framework he preset in the early years.

Fan Pengyue nodded and said: "Well, the graphene module originally didn't have this function, and your elementary school sister later calculated it after making changes."

"That's why I want to ask her for help to see if I can optimize other modules."

Hearing this, Xu Chuan stood up and said, "It's easy to talk about optimization, first take me to see the modified graphene module code and the underlying logic formula."

After confirming that this change was caused by the change of the calculation material model, he was a little curious about what the senior sister had changed.
